By the way, since bees are pests that may cause harm to humans, it is desired to further improve the bee catching effect by the bee catcher. In this regard, in Patent Documents 1 and 2, since the attractant is contained in the container, it is considered that the bees can be attracted and it is difficult for the bees to escape to the outside once they have entered the introduction hole. However, according to the study by the inventors of the present application, among the bees attracted by the attractants of Patent Documents 1 and 2, although they fly around the bee trap, they cannot find an introduction hole and give up the invasion and fly. It became clear that some bees would leave. In such a case, it is desired to improve the bee catching effect not only by the attracting effect of the attractant but also by the structure of the bee catcher itself. Bees that do not try to invade the introduction hole may pass over the trap as it is and cannot be captured.

On the other hand, since the insect trap of Cited Document 3 is provided with a Yakura plate above the introduction hole, a bee that has flown horizontally above the introduction hole is made to collide with the Yakura plate and is captured by dropping it. Becomes possible. However, in Cited Document 3, an attractant container is provided on the Yakura board, and the insects are guided to the Yakura board by the attracting effect of this attractant. Therefore, the bees that stay in the attractant container without colliding with the Yakura board Cannot be captured. In this way, it is probable that some bees cannot be captured even though they have been attracted by the attractant. It should be noted that Cited Document 3 does not have the idea of accommodating the attractant in the insect trap container, and it is unclear whether or not the Yakura board is effective even if the attractant is contained in the insect trap container.

The present invention has been made in view of this point, and an object of the present invention is to improve the catching effect of an insect catcher, and in particular, a bee that has been attracted by an attractant and has approached the catcher. The purpose is to improve the capture effect.

In order to achieve the above object, in the present invention, a collision plate is provided above the container, and by providing a difference between the color of the collision plate and the color of the upper part of the container, not only the attraction effect of the attractant but also the attraction effect is provided. A high attraction effect due to the difference in color can also be obtained.

In the first invention, an insect introduction hole is formed in the upper part, a trap container containing an insect attractant inside, and a collision plate provided above the introduction hole so as to extend in the vertical direction. The insect catcher provided with the above is characterized in that the visible light transmittance of the upper part of the catching container is set lower than the visible light transmittance of the collision plate.

According to this configuration, the attractant contained inside the capture container attracts insects around the capture container and enters the capture container through the introduction hole to be captured, and the insects flying around the capture container collide with each other. When it collides with a plate and falls, it enters the capture container through the introduction hole and is captured. By lowering the visible light transmittance of the upper part of the capture container, it becomes easier for insects attracted by the attractant to find the introduction hole, and the number of insects that invade the container through the introduction hole can be increased. Further, even when the insect attracted by the attractant cannot find the introduction hole, in the present invention, the visible light transmittance at the upper part of the capture container is made lower than the visible light transmittance of the collision plate. The collision plate looks relatively brighter than the upper part of the capture container, and the insects are more likely to fly toward the brighter side, that is, toward the collision plate. This makes it easier for insects to collide with the collision plate, and the insects that have collided with the collision plate and fallen enter the capture container through the introduction hole and are captured. Furthermore, even insects that are flying around regardless of the attracting effect of the attractant can easily fly toward the collision plate in the same manner as above, so that they collide with the collision plate and fall, and then fall from the introduction hole. It is captured in a capture container. In this way, the attracting effect of the attracting agent and the attracting effect of the color difference between the collision plate and the upper part of the container also occur, and the capturing effect is improved.

In the second invention, the capture container has a transparent container body with an open upper portion and a visible light transmittance lower than the visible light transmittance of the collision plate, which is attached to the upper part of the container body. It is characterized in that the lid is provided and the introduction hole is formed in the lid.

According to this configuration, since the container body is translucent, the insects caught in the container try to escape to the bright side (outward), but the lid with low visible light transmittance is used. I don't go to. As a result, it is possible to reduce the possibility that the insects once captured in the container escape from the introduction hole formed in the lid. In addition, since the container body is translucent, it is possible to confirm the presence or absence of an attractant and the captured insects from the outside. Since the lid is separate from the container body, it is easy to change the color of the lid from the color of the container body to have a visible light transmittance lower than the visible light transmittance of the collision plate. Can be done.

The third invention is characterized in that the color of the lid is any of black, brown, blue, dark blue, and green.

According to this configuration, the visible light transmittance of the lid is lowered, and the difference in brightness from the collision plate becomes clearer, so that insects flying around the capture container easily collide with the collision plate.

The fourth invention is characterized in that the collision plate has a translucency that allows natural light to pass through.

According to this configuration, the visible light transmittance of the collision plate is increased, so that the difference in brightness from the upper part of the capture container becomes clearer, and insects flying around the capture container are more likely to collide with the collision plate. ..

The fifth invention is characterized in that the color of the upper part of the trapping container is black and the collision plate is colorless and transparent.

According to this configuration, the color difference and the brightness difference between the upper part of the capture container and the collision plate become clearer, and the insects flying around the capture container easily collide with the collision plate.

A sixth aspect of the present invention is characterized in that the collision plates include a first collision plate and a second collision plate that intersect each other.

According to this configuration, since the first collision plate and the second collision plate face different directions, the probability that insects flying from different directions collide with the collision plate can be increased.

According to the seventh invention, a cover member that covers the collision plate from above is provided so as to be located above the introduction hole, and the cover member is one of black, brown, blue, dark blue, and green. It is a feature.

According to this configuration, since the cover member is arranged above the introduction hole, the cover member functions as a roof, and for example, rain and the like are less likely to enter the inside of the capture container.

In the eighth aspect of the invention, the capture container is provided with an edge portion protruding outward, and an engaging portion that engages with the edge portion of the capture container is provided at the lower portion of the collision plate. The cover member is in contact with the upper part of the collision plate.

According to this configuration, the collision plate can be attached to the capture container by engaging the engaging portion of the collision plate with the capture container. In this state, since the cover member is in contact with the upper part of the collision plate, the collision plate is less likely to fall due to the influence of wind or the like.

According to the first invention, a collision plate is provided above the introduction hole of the capture container containing the insect attractant, and the visible light transmittance of the upper part of the capture container is made lower than the visible light transmittance of the collision plate. Therefore, not only the attracting effect of the attractant but also the high attracting effect of the color can be obtained, and the insect catching effect can be improved.

According to the second invention, since the container body and the lid are separated, the color of the lid can be freely set while giving the container body translucency, and the color of the lid can be changed to that of the collision plate. A color having a visible light transmittance lower than the visible light transmittance can be obtained.

According to the third invention, the difference in brightness between the lid and the collision plate becomes clearer, so that the effect of catching insects is further improved.

According to the fourth invention, since the collision plate has translucency, the difference in brightness between the lid and the collision plate becomes clearer, and the effect of catching insects is further improved.

According to the fifth invention, by making the color of the upper part of the capture container black and the collision plate colorless and transparent, the difference in color and the difference in brightness between the lid and the collision plate becomes clearer. The capture effect of is further improved.

Since the sixth invention includes a first collision plate and a second collision plate that intersect each other, the probability of colliding with the insect collision plate can be increased.

According to the seventh invention, when a cover member for preventing rain or the like from entering the inside of the capture container is provided, the collision of insects with the collision plate can be prevented from being hindered, and a decrease in the capture effect can be avoided. it can.

In the eighth invention, since the cover member can suppress the collision plate from falling over, the desired capture effect can be obtained for a long period of time.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the following description of the preferred embodiment is essentially merely an example and is not intended to limit the present invention, its application or its use.

FIG. 1 is a perspective view showing a bee trap 1 according to an embodiment of the insect trap of the present invention. The bee catcher 1 includes a catching container 10, a first collision plate 20, a second collision plate 30, and a cover member 40. The bee trap 1 is for capturing and exterminating bees in the capture container 10, and can be used, for example, by hanging it on a tree or a rod, or by placing it on a table or the like. It is configured in. The first collision plate 20 and the second collision plate 30 are members for improving the catch rate of bees as described later, and in the present embodiment, the collision plate includes the first collision plate 20 and the second collision plate 30. However, the present invention is not limited to this, and only one of the collision plates may be included. The cover member 40 is a member that covers the capture container 10, is not essential, and may be omitted.

In the description of this embodiment, as shown in each figure, the left and right sides of the bee catcher 1 are defined, and the front side and the back side are defined, but this is for convenience of explanation only and is actually used. It does not limit the usage condition, manufacturing, assembly, packing, and storage orientation of the product. Either side of the bee trap 1 may be on the right or left. Further, the front side of the bee trap 1 may be referred to as the front side, and the back side may be referred to as the rear side.

(Structure of capture container 10)
As shown in FIGS. 5 and 6, the capture container 10 includes a cup-shaped container body 11 opened upward and a lid 12 attached to the upper part of the container body 11, and the upper part of the capture container 10 is a lid. It is composed of twelve. The container body 11 and the lid 12 are made of, for example, an elastically deformable resin material. Examples of this resin material include polyethylene terephthalate, polypropylene, polyethylene, polystyrene, polycarbonate and the like. The container body 11 and the lid 12 are obtained by vacuum forming a resin sheet material. The thickness of the resin sheet material is, for example, preferably in the range of 0.2 mm or more and 1.2 mm or less, more preferably 0.3 mm or more and 0.8 mm or less. The container body 11 and the lid 12 may be obtained by hot press molding the resin sheet, or the container body 11 and the lid 12 may be obtained by injection molding the resin material. The container body 11 and the lid 12 are preferably made of resin in consideration of weather resistance and economy, but the present invention is not limited to this, and the container body 11 and the lid 12 may be formed by using a material other than resin.

The visible light transmittance of the resin material constituting the container body 11 is set higher than the visible light transmittance of the resin material constituting the lid 12. The visible light transmittance can be measured by a conventionally known method, for example, by a method compliant with JIS K7375 or the like. Further, the visible light transmittance can be set to the ratio at which light having a wavelength of about 400 nm to about 700 nm is transmitted under outdoor scattered light, and can be measured using, for example, a spectrophotometer. By using a value measured with light having a wavelength of about 500 nm, an average visible light transmittance can be obtained. Regardless of which of the above measuring methods is used, the visible light transmittance of the resin material constituting the container body 11 can be set to, for example, 30% or more, and the visible light transmittance of the resin material constituting the lid 12 can be set. The rate can be set to 20% or less. The visible light transmittance of the resin material constituting the lid 12 is more preferably 10% or less.

In this embodiment, the resin material constituting the container body 11 is, for example, lightly colored and translucent, and it is possible to distinguish the liquid level height of the internal attractant 13 and the presence or absence of bees under sunlight. ing. That is, the resin material constituting the container body 11 has a property of transmitting natural light. Further, the resin material constituting the container body 11 may be lightly colored and transparent, or may be colorless and transparent. The resin material constituting the container body 11 and the resin material constituting the lid 12 may have the same color.

The resin material constituting the lid 12 is colored, for example, black so that the inside of the container body 11 cannot be visually recognized through the lid 12. By making the lid 12 black, the color of the upper part of the capture container 10 becomes black. The resin material constituting the lid 12 may be colored brown, blue, dark blue, or green in addition to black. The lid 12 may be a single color or may be painted in a plurality of colors.

The bottom wall portion 11b of the container body 11 has a substantially circular shape. The peripheral wall portion 11c of the container body 11 extends upward from the peripheral edge portion of the bottom wall portion 11b. The entire upper end of the peripheral wall portion 11b is opened in a substantially circular shape. The horizontal cross section of the peripheral wall portion 11c has a substantially circular shape, and the inner diameter thereof is set to be larger toward the upper part, that is, smaller toward the lower part. The volume of the capture container 10 is not particularly limited, but for example, a volume capable of accommodating 10 or more giant hornets is preferable, and for example, a volume of 300 ml or more and 500 ml or more can be used.

The size of the capture container 10 is set in consideration of ease of installation and portability. For example, the outer diameter can be set to 100 mm or less and the height can be set to 200 mm or less. At the upper end of the peripheral wall portion 11c of the container body 11, a ridge portion 11a that projects outward in the radial direction and continuously extends in the circumferential direction is formed. The ridge portion 11a is an edge portion of the container body 11 that projects outward in the radial direction. A bee attractant 13 is housed inside the capture container 10. The attractant 13 is a liquid, which will be described later. The liquid level of the attractant 13 can be set above the central portion or the central portion in the vertical direction of the container body 11. However, the insect trap of the present invention can also be used to capture insects other than bees, and the diameter of the introduction hole 12a can be appropriately set according to the target insect. Similarly, the volume and diameter of the capture container 10 can be set according to the target insect.

The lid 12 is a member for closing the opening at the upper end of the container body 11, and has a substantially circular shape in a plan view. An introduction hole 12a for introducing a bee into the inside of the capture container 10 is formed in the central portion of the lid 12. Since the lid 12 is located above the capture container 10, the introduction hole 12a is also located above the capture container 10. The shape of the introduction hole 12a can be, for example, circular, but is not limited to this, and may be, for example, an elliptical shape or a polygonal shape. The number of introduction holes 12a is one in this embodiment, but may be two or more. When two or more introduction holes 12a are provided, the introduction holes 12a can be provided apart from each other, and can be formed in a portion other than the central portion of the capture container 10.

The diameter of the introduction hole 12a can be set to 20 mm or more and 35 mm or less. If the diameter of the introduction hole 12a is less than 20 mm, it becomes difficult for a large bee such as a giant hornet to enter the introduction hole 12a, and the capture rate decreases. On the other hand, if the diameter of the introduction hole 12a is larger than 35 mm, there is a high possibility that butterflies, moths, and beetles other than bees invade, so the diameter of the introduction hole 12a is preferably 35 mm or less. Therefore, by setting the diameter of the introduction hole 12a to 20 mm or more and 35 mm or less, the capture rate of large bees can be increased. It is more preferable that the diameter of the introduction hole 12a is set to 30 mm or less.

An annular portion 12d protruding downward is formed on the peripheral edge of the introduction hole 12a. The vertical dimension of the annular portion 12d is set longer than the thickness dimension of the plate material constituting the lid 12. The vertical dimension of the annular portion 12d can be set to, for example, 1 mm or more, and the upper limit can be set to 20 mm. The annular portion 12d may be omitted.

The peripheral edge of the introduction hole 12a and the liquid level of the attractant 13 are separated by a predetermined dimension or more. This predetermined dimension is set so that, for example, when the giant hornet is captured and floats on the liquid surface of the attractant 13, the hands and legs of the giant hornet are difficult to reach the peripheral edge of the introduction hole 12a, for example, at 30 mm or more. is there. The predetermined dimension can be set to 40 mm or more.

An inclined surface 12b is formed around the introduction hole 12a in the lid 12. The inclined surface 12b has the lowest peripheral edge of the introduction hole 12a, is inclined so as to be positioned upward as the distance from the introduction hole 12a is outward in the radial direction, and is continuous in the circumferential direction of the introduction hole 12a. The inclined surface 12b is a surface for guiding a bee on the inclined surface 12b to the introduction hole 12a. The inclination angle of the inclined surface 12b is set so that the bees on the inclined surface 12b can easily slide down toward the introduction hole 12b, and can be set to, for example, 20 degrees or more, more preferably 30 degrees or more. Is. A horizontal surface may be provided without providing the inclined surface 12b.

The peripheral edge of the lid 12 is formed so as to project in the horizontal direction, and an annular plate portion 12c extending so as to surround the ridge portion 11a of the container main body 11 is formed on the peripheral edge portion. The annular plate portion 12c is formed so as to fit on the outside of the ridge portion 11a of the container body 11. By fitting the annular plate portion 12c to the ridge portion 11a of the container body 11, the lid 12 is detachably attached to the container body 11.

(Structure of 1st collision plate 20 and 2nd collision plate 30)
As shown in FIG. 10 and the like, the first collision plate 20 and the second collision plate 30 are provided so as to extend in the vertical direction above the introduction hole 12a of the capture container 10, and mainly for bees flying in the horizontal direction. It is a member for colliding. Both sides of the first collision plate 20 and both sides of the second collision plate 30 are bee collision surfaces. Both the first collision plate 20 and the second collision plate 30 are made of a resin material, and the material can be the same as that of the capture container 10. The thickness of the first collision plate 20 and the second collision plate 30 is set to be thicker than the thickness of the resin sheet constituting the container body 11 and the lid 12, whereby the first collision plate 20 and the second collision plate 20 and the second collision plate 30 are set to be thicker. No. 30 has higher rigidity than the resin sheet and is less likely to be deformed, but has flexibility that can be curved when it is housed in the box 100 described later. The first collision plate 20 and the second collision plate 30 have elasticity of being curved when they are housed in the box 100 and then being taken out of the box 100 and restored to be substantially flat when an external force is removed. The materials of the first collision plate 20 and the second collision plate 30 may be the same material or different materials.

The visible light transmittance of the upper part (lid 12) of the capture container 10 is set lower than the visible light transmittance of the first collision plate 20 and the second collision plate 30. Specifically, the color of the resin material constituting the lid 12 is a color that hardly transmits visible light, while the resin material constituting the first collision plate 20 and the second collision plate 30 is translucent to transmit natural light. have. The first collision plate 20 and the second collision plate 30 are colorless and transparent, but may be lightly colored with, for example, yellow. The first collision plate 20 and the second collision plate 30 have visibility so that the other side can be visually recognized. The first collision plate 20 and the second collision plate 30 may be lightly colored translucent or milky white.

The first collision plate 20 extends from the front side to the back side of the capture container 10, and the central portion of the first collision plate 20 is the highest, and becomes lower toward the front side and the back side. It is formed in a mountain shape. The longitudinal direction of the first collision plate 20 is a direction from the front side to the back side. As shown in FIG. 7, a first slit 21 is formed in the central portion of the first collision plate 20 in the longitudinal direction. The upper portion of the first slit 21 is open at the upper edge portion of the first collision plate 20, and the first slit 21 extends downward from the upper edge portion of the first collision plate 20. Although the first slit 21 has a wavy shape, it may have a shape extending linearly. The lower portion of the first slit 21 is located near the central portion in the vertical direction of the first collision plate 20.

First hook portions (engagement portions) 22 and 22 projecting downward are formed on the front side and the back side of the lower portion of the first collision plate 20, respectively. The first hook portions 22 and 22 are formed so as to open upward, and are portions that engage with the ridge portion 11a of the container body 11 which is the edge portion of the capture container 10 so as to be caught from below. ..

For example, as shown in FIG. 10, the second collision plate 30 extends from the right side to the left side of the capture container 10. Therefore, the first collision plate 20 and the second collision plate 30 are arranged so as to intersect each other. In this embodiment, the first collision plate 20 and the second collision plate 30 are orthogonal to each other, but the angle formed by the first collision plate 20 and the second collision plate 30 is 70 in a plan view. It may be about 80 degrees.

The second collision plate 30 is formed in a mountain shape so that the central portion in the left-right direction is the highest and the second collision plate 30 becomes lower toward the right side and toward the left side. The longitudinal direction of the second collision plate 30 is the left-right direction. As shown in FIG. 8, a second slit 31 is formed in the central portion of the second collision plate 30 in the left-right direction. The lower part of the third slit 31 is opened at the lower edge portion of the second collision plate 30, and the second slit 31 extends upward from the lower edge portion of the second collision plate 30. Although the second slit 31 has a wavy shape, it may have a shape extending linearly. The upper portion of the second slit 31 is located near the central portion in the vertical direction of the second collision plate 30.

Second hook portions (engagement portions) 32 and 32 projecting downward are formed on the right side and the left side of the lower portion of the second collision plate 30, respectively. The second hook portions 32, 32 are formed so as to open upward, and are portions that engage with the ridge portion 11a of the container body 11, which is the edge portion of the capture container 10, so as to be hooked from below. ..

Since the first collision plate 20 and the second collision plate 30 have flexibility as described above, when the hook portion 22 or the hook portion 32 is engaged with the ridge portion 11a of the container body 11, the first collision plate 20 and the second collision plate 30 have the flexibility. It can be engaged by appropriately elastically deforming the collision plate and hooking the hook portion on the ridge portion 11a.

In the present embodiment, the collision plates 20 and 30 are configured to be engaged with the container body 11 so as to be caught from below, but the collision plates 20 and 30 are fixed so as not to move relative to the container body 11. It does not have to be engaged with the container body 11 itself. For example, the collision plates 20 and 30 can be configured to engage the upper part of the lid 12.

A hanging plate portion 33 is provided on the upper portion of the second collision plate 30 so as to project upward at a central portion in the left-right direction. A through hole 33a is formed in the hanging plate portion 33. Although not shown, a string or thread can be passed through the through hole 33a, and the bee catcher 1 is hung from a member such as a tree branch or a rod by the string or thread. Can be done. In this way, since the hanging plate portion 33 is provided on the second collision plate 30 to support the weight of the capture container 10, the cover member 40 described later has a structure in which the weight of the capture container 10 is not applied. Instead of this, a hanging plate portion may be provided on the top of the cover member 40, and the cover member 40 may support the weight of the capture container 10. However, since the cover member 40 of the present embodiment is made of a flexible sheet, if the weight of the capture container 10 is applied to the cover member 40, the cover member 40 may be distorted so as to be stretched vertically. There is. In this respect, as described above, in the present embodiment, the cover member 40 is not subjected to the weight of the capture container 10, so that the cover member 40 is not distorted by the weight of the capture container 10.

The first collision plate 20 and the second collision plate 30 are combined and integrated. That is, the portion where the second slit 31 of the second collision plate 30 is formed is inserted into the first slit 21 of the first collision plate 20 from above, and the second slit 31 of the second collision plate 30 is inserted from below. 1 Insert the portion of the collision plate 20 in which the first slit 21 is formed. Then, the portion above the second slit 31 in the second collision plate 30 is inserted into the first slit 21, and the portion below the first slit 21 in the first collision plate 20 is inserted into the second slit 21. Is plugged in. As a result, as shown in FIG. 10, the first collision plate 20 and the second collision plate 30 are integrated in a state of intersecting each other.

The lower part of the first collision plate 20 and the lower part of the second collision plate 30 are in contact with the upper surface of the lid 12. As a result, the first collision plate 20 and the second collision plate 30 are positioned in the vertical direction with respect to the capture container 10. The upper portions of the first collision plate 20 and the second collision plate 30 are separated from the lid 12 of the capture container 10 by 80 mm or more. By ensuring a vertical separation distance of 80 mm or more between the upper parts of the first collision plate 20 and the second collision plate 30 and the lid 12, the vertical dimensions of the first collision plate 20 and the second collision plate 30 are sufficient. It can be secured and the collision rate of bees can be increased. The vertical separation distance between the upper portions of the first collision plate 20 and the second collision plate 30 and the lid 12 is more preferably 100 mm or more, for example. In this embodiment, the upper part of the first collision plate 20 and the upper part of the second collision plate 30 have the same height, but the heights may be different.

Further, the maximum dimension in the width direction of the first collision plate 20 (the maximum dimension from the front end to the back end) is set longer than the outer diameter of the capture container 10. Similarly, the maximum dimension in the width direction of the second collision plate 30 (maximum dimension from the right end to the left end) is set longer than the outer diameter of the capture container 10. In this embodiment, the maximum dimension in the width direction of the first collision plate 20 and the maximum dimension in the width direction of the second collision plate 30 are the same, but the present invention is not limited to this, and may be different. When the first collision plate 20 and the second collision plate 30 are attached to the capture container 10, the first hook portion 22 and the second hook portion 32 are only engaged with the capture container 10, so that the first collision plate 20 The second collision plate 30 is removable from the capture container 10.

(Structure of cover member 40)
The cover member 40 is a member that covers the first collision plate 20 and the second collision plate 30 from above. The cover member 40 is provided so as to be located above the introduction hole 12a formed in the lid 12, and also covers the introduction hole 12a from above. As a result, it is possible to prevent rain or the like from entering the capture container 10 through the introduction hole 12a. The cover member 40 is made of a resin material, and the material can be the same as that of the first collision plate 20 and the second collision plate 30. The color of the resin material constituting the cover member 40 can be the same as that of the lid 12, and can be, for example, black, brown, blue, dark blue, or green. The cover member 40 may be colorless and transparent.

As shown in FIG. 1 and the like, the cover member 40 is attached to the capture container 10 in a state of being curved in an annular shape. On the other hand, as shown in the developed view of FIG. 9, it can be developed into a flat sheet shape. A container insertion hole 41 into which the container body 11 is inserted from below is formed in the central portion of the cover member 40 in the longitudinal direction. The shape of the container insertion hole 41 is formed so as to substantially match the outer shape of the vertical intermediate portion of the container body 11, and is circular in this embodiment. For example, as shown in FIGS. 5 and 10, the shape of the container insertion hole 41 so that the upper part of the container body 11 is located above the container insertion hole 41 when the container body 11 is inserted into the container insertion hole 41. And the inner diameter is set.

As shown in FIG. 9, openings 42 are formed on both sides of the container insertion hole 41 in the cover member 40, respectively. Further, the insertion pieces 43, 43 are formed in the vicinity of one end in the longitudinal direction of the cover member 40, while the engagement holes 44 into which the insertion pieces 43, 43 are inserted are formed in the vicinity of the other end in the longitudinal direction of the cover member 40. , 44 are formed. Further, in the vicinity of one end portion in the longitudinal direction of the cover member 40, an insertion hole 45 through which the hanging plate portion 33 of the second collision plate 30 is inserted is formed between the insertion pieces 43 and 43.

The cover member 40 is attached to the capture container 10 as shown in FIG. 1 and the like. That is, after the container body 11 is inserted into the container insertion hole 41 of the cover member 40 (shown in FIG. 10), both sides of the cover member 40 in the longitudinal direction are curved upward, and the hanging plate portion 33 of the second collision plate 30 is formed. Is inserted into the insertion hole 45. Then, when the insertion pieces 43, 43 are inserted into the engagement holes 44, 44, the insertion pieces 43, 43 engage with the peripheral edges of the engagement holes 44, 44, and the cover member 40 becomes annular. In this state, the openings 42 and 42 of the cover member 40 are located on the front side and the back side of the bee catcher 1, respectively. The second collision plate 30 can be visually recognized through the openings 42 and 42. The size of the openings 42, 42 is a large opening so that most of the second collision plate 30 can be visually recognized.

Further, on the left side and the right side of the cover member 40 attached to the capture container 10, side openings 4 and 4 are formed by the edges of the cover member 40, respectively. The first collision plate 20 can be visually recognized through the side openings 4 and 4. The size of the side openings 4 and 4 is a large opening so that most of the first collision plate 20 can be visually recognized.

Further, the cover member 40 is in contact with the upper part of the first collision plate 20 and the upper part of the second collision plate 30 in a state of being attached to the capture container 10 and forming an annular shape.

Since the large opening 42 and the side opening 4 are provided in this way, the odor diffusivity of the attractant 13 is good even though the introduction hole 12a is covered with the cover member 40, and the bee can be removed. It can be attracted efficiently. Then, by lowering the visible light transmittance of the cover member 40 and the lid 12 and increasing the visible light transmittance of the first collision plate 20 and the second collision plate 30, the visible light transmittance is increased through the opening 42 or the side opening 4. To the bee looking into the inside of the cover member 40, the space between the cover member 40 and the lid 12 feels like a tunnel through which the cover member 40 can pass, and the other side of the space looks bright. Therefore, it is considered that the bees easily fly toward the collision plates 20 and 30, and as a result, easily collide with the collision plates 20 or 30. The bees that collide with the collision plate 20 or 30 fall, slide down the inclined surface 12b, fall to the water surface of the attractant 13 in the capture container 10 through the introduction hole 12b, and are captured.

(Accommodation method of bee trap 1)
The bee catcher 1 is transported to a retail store in a state of being housed in a box 100 as shown in FIGS. 11 and 12 and displayed at the store. The box 100 is a paper box such as cardboard. The width W of the box 100 is set to be slightly wider than the outer diameter of the lid 12 of the capture container 10. The box 100 can be formed so that all four sides when viewed from above have the same dimensions, but may have sides of different lengths, and is rectangular when viewed from above. May be good.

As shown in FIG. 11, the bee catcher 1 is disassembled into a catching container 10, a first collision plate 20, a second collision plate 30, and a cover member 40 before being housed in the box 100. When the capture container 10 is housed in the box 100, the first collision plate 20 and the second collision plate 30 are curved between the capture container 10 and the box 100 and housed in the box 100, and the cover member 40 is also captured. It is curved between the container 10 and the box 100 and housed in the box 100.

Specifically, the cover member 40 is curved so as to surround the capture container 10 until it has a shape close to a cylinder, and the outer diameter when curved is substantially equal to or larger than the width W of the box 100. Make it a little smaller. The first collision plate 20 and the second collision plate 30 are arranged inside the curved cover member 40. At this time, the first collision plate 20 and the second collision plate 30 are curved in an arc shape so as to surround the capture container 10. When one of the first collision plate 20 and the second collision plate 30 is omitted, only the other collision plate may be housed in the box 100. When the cover member 40 is omitted, the first collision plate 20 and the second collision plate 30 may be housed in the box 100.

When the cover member 40 is housed in the box 100, the cover member 40 expands in diameter until it comes into contact with the inner surface of the box 100 due to the restoring force. Further, since the first collision plate 20 and the second collision plate 30 also try to be flattened by the restoring force, they come into contact with the cover member 40 or the outer surface of the capture container 10. Therefore, the cover member 40, the first collision plate 20, and the second collision plate 30 are housed inside the box 100 without rattling.

In this embodiment, the longitudinal dimension of the first collision plate 20 is less than half of the longitudinal dimension of the cover member 40, and the longitudinal dimension of the second collision plate 30 is also the longitudinal dimension of the cover member 40. It is said to be less than half the dimension in the direction. As a result, the curved first collision plate 20 and the second collision plate 30 can be housed in the box 100 in a state of being spaced apart from each other in the circumferential direction of the capture container 10, so that the first collision plate 20 and the second collision plate 20 can be accommodated. It is not necessary to stack the collision plates 30 in the thickness direction. Although not shown, the first collision plate 20 and the second collision plate 30 may be overlapped and curved in the thickness direction and housed in the box 100.

Further, the first collision plate 20 and the second collision plate 30 are housed below the lid 12. As a result, the space formed between the outer surface of the container body 11 and the box 100 can be effectively utilized as a storage space for the first collision plate 20 and the second collision plate 30. Further, the first collision plate 20, the second collision plate 30, and the cover member 40 are overlapped and curved in the thickness direction and housed in the box 100. The first collision plate 20 and the second collision plate 30 may be accommodated between the cover member 40 and the inner surface of the box 100.

The order in which the capture container 10, the first collision plate 20, the second collision plate 30, and the cover member 40 are housed in the box 100 is not particularly limited. For example, the cover member 40 is curved to form the box 100. The first collision plate 20 and the second collision plate 30 may be curved and accommodated in the box 100, and then the capture container 10 may be accommodated. Further, even if the capture container 10 is housed in the box 100, the cover member 40 is curved and housed in the box 100, and then the first collision plate 20 and the second collision plate 30 are curved and housed in the box 100. Good. Further, after the capture container 10 is housed in the box 100, the first collision plate 20 and the second collision plate 30 may be curved and housed in the box 100, and then the cover member 40 may be curved and housed in the box 100. Good. Further, even if the first collision plate 20 and the second collision plate 30 are curved and housed in the box 100, the cover member 40 is curved and housed in the box 100, and then the capture container 10 is housed in the box 100. Good. Further, the first collision plate 20 and the second collision plate 30 may be curved and housed in the box 100, the capture container 10 may be housed in the box 100, and then the cover member 40 may be housed in the box 100.

Further, the capture container 10, the first collision plate 20, the second collision plate 30, and the cover member 40 may be integrated outside the box 100 and then housed together in the box 100. The attractant 13 can be put inside the container body 11 in a state of being housed in a sealed bag or the like, and the bee catcher 1 should be put into the container body 11 from the bag before the start of use. Just do it.

The first collision plate 20, the second collision plate 30, and all or a part of the cover member 40 may be housed inside the capture container 10.

(Structure of attractant 13)
The attractant 13 is a liquid agent having an action of attracting bees, and since it is a liquid agent for catching bees, it can also be called a bee catching liquid. In particular, the attractant 13 of the present embodiment artificially reproduces the fermented odor of sap that attracts bees in the natural world, and can also be called artificial sap. The attractant 13 contains sugar, yeast, alcohol, and water as components of the artificial sap. Further, the attractant 13 of the present embodiment contains a food additive-based surfactant (nonionic surfactant) as an escape prevention component.

Examples of the sugar include fructose-glucose liquid sugar. The content of fructose-glucose liquid sugar can be, for example, 1 w / v% or more and 75 w / v% or less. Examples of yeast include dry yeast. The yeast content can be, for example, 0.001% by mass or more and 5% by mass or less. By adding yeast, sugar is alcohol-fermented by yeast to generate alcohol and carbon dioxide.

As the alcohol, at least one of ethanol, butane-2,3-diol and glycerin can be used, and any plurality of these can be mixed and used. The alcohol content can be, for example, 0.01 w / v% or more and 15 w / v% or less. Alcohol is produced by fermentation of yeast and can be omitted, but if alcohol is added, the attractiveness can be satisfactorily exhibited even in the initial stage of fermentation.

The attractant 13 may contain acetic acid. The content of acetic acid can be, for example, 0.005 w / v% or more and 0.5 w / v% or less. In addition, the attractant 13 may contain lactic acid. The content of lactic acid can be, for example, 0.005 w / v% or more and 5 w / v% or less. Since acetic acid and lactic acid form an ester with alcohol, if they are mixed at the same time, the composition may change due to long-term storage. Therefore, from the viewpoint of long-term storage stability, it is preferable to omit at least one of acetic acid and lactic acid, or alcohol.

In addition, the attractant 13 may contain sodium propionate. The content of sodium propionate can be, for example, 0.005 w / v% or more and 0.5 w / v% or less.

The surfactant added to the artificial sap as an escape-preventing component is preferably a nonionic surfactant in that it does not adversely affect yeast, and in particular, a food additive-based surfactant as in the present embodiment is preferable. As the food additive surfactant, at least one of polyoxyethylene sorbitan monolaurate and polyoxyethylene sorbitan monooleart can be used, and any plurality of these may be mixed and used. You can also. The content of the food additive-based surfactant can be, for example, 0.001 w / v% or more and 1.0 w / v% or less. Since the surfactant is a food additive type, it does not have an adverse effect on yeast fermentation, and it is possible to quickly start fermentation by yeast at the start of use, and a high attraction effect is obtained over a long period of time. Be done. As the food additive-based surfactant, for example, Tween 20 and Tween 80 manufactured by Tokyo Chemical Industry Co., Ltd. can be used.

(Fermentability of attractant 13)
Since the attractant 13 contains dry yeast as yeast, it is fermented by the action of yeast. The odor generated by fermentation can enhance the bee attraction effect. The attractant formulations 1 and 2 are shown in Tables 1 and 2.

The attractant 13 is obtained by first dissolving fructose and glucose in water, and then adding ethanol, acetic acid, lactic acid, a food additive surfactant, and dry yeast. The attractant formulation 1 shown in Table 1 and the attractant formulation 2 shown in Table 2 are different in dry yeast. The dry yeast of the attractant formulation 1 contains 3 g of Kyoritsu Foods Value Dry Yeast (called Kyoritsu Dry Yeast), and the dry yeast of the attractant formulation 2 contains 3 g of Nissin Foods Nissin Super Camellia Vacuum Pouch (Nissin). It is called dry yeast).

The fermentation confirmation test method of the attractant 13 will be described. 100 mg of dry yeast is added to 20 g of the test agent to obtain an attractant 13, and then immediately placed in a 10.2 L container. The time measurement is started immediately after the attractant 13 is placed in the container. The container is a sealed state in which the top and bottom of a glass cylinder having an inner diameter of 20 cm × 30 cm is covered with a glass plate. The ambient temperature at the time of the test was 24.5 ° C. and the humidity was 47%. After a certain period of time, the oxygen dioxide concentration in the container was measured. The measuring device was manufactured by GM70 VAISALA, and was used after 15 minutes or more had passed after the start-up. The carbon dioxide concentration in the blank air was about 220 to 300 ppm.

Table 3 shows the carbon dioxide concentration of the attractant formulation 1, the carbon dioxide concentration of the attractant formulation 1 when Tween 20 is not contained, the carbon dioxide concentration of the attractant formulation 2, and the carbon dioxide of the formulation not containing Tween 20 in the attractant formulation 2. The results of measuring the concentrations after 1 hour, 24 hours, and 48 hours, respectively, are shown. As is clear from Table 3, it was confirmed that fermentation proceeded in both the attractant formulation 1 containing Kyoritsu dry yeast and the attractant formulation 2 containing Nisshin dry yeast. Further, it can be seen that the fermentation proceeds regardless of the presence or absence of Tween 20, and that Tween 20 does not inhibit the fermentation by dry yeast. Similar results can be obtained with Tween 80.

The attractant formulations 3 and 4 are shown in Table 4. The method of obtaining the attractant prescriptions 3 and 4 is the same as the method of obtaining the attractant prescription 1. The same applies hereinafter.

The attractant prescription 3 is a glucose-free prescription, and the attractant prescription 4 is an alcohol-free prescription. Table 5 shows the measurement results of the carbon dioxide concentration of the attractant formulations 3 and 4.

Both the attractant formulations 3 and 4 have a high carbon dioxide concentration after 1 hour, and fermentation is promoted from the initial stage. In addition, it can be seen that the carbon dioxide concentration after 48 hours has passed in both the attractant formulations 3 and 4 and the fermentation lasts for a long time.

The attractant formulation 5 is shown in Table 6. The attractant formulation 5 is a formulation that does not contain alcohol, lactic acid, or acetic acid.

The attractant formulation 6 is shown in Table 7. The attractant formulation 6 is a formulation that does not contain alcohol and lactic acid and has an acetic acid concentration of 0.01%.

The attractant formulation 7 is shown in Table 8. The attractant formulation 7 is a formulation that does not contain alcohol and lactic acid and has an acetic acid concentration of 0.05%.

Table 9 shows the measurement results of the carbon dioxide concentration of the attractant formulations 5 to 7.

It can be seen that the carbon dioxide concentration after 55 hours was high in all of the attractant formulations 5 to 7, and the fermentation lasted for a long time.

The attractant formulation 8 is shown in Table 10. The attractant formulation 8 is a formulation that does not contain alcohol and acetic acid and has a concentration of lactic acid of 0.05%.

The attractant formulation 9 is shown in Table 11. The attractant formulation 9 is a formulation that does not contain alcohol and acetic acid and has a concentration of lactic acid of 0.1%.

The attractant formulation 10 is shown in Table 12. The attractant formulation 10 is a formulation that does not contain alcohol and lactic acid and has an acetic acid concentration of 0.1%.

The attractant formulation 11 is shown in Table 13. The attractant formulation 11 is a formulation that does not contain alcohol and lactic acid and has an acetic acid concentration of 0.3%.

Table 14 shows the measurement results of the carbon dioxide concentration of the attractant formulations 8 to 11.

It can be seen that all of the attractant formulations 8 to 11 have a high carbon dioxide concentration after 66 hours, and the fermentation lasts for a long time. Therefore, even if both lactic acid and acetic acid are not contained, fermentation can be continued for a long time by containing one of them.

(Surface tension of attractant 13)
The surface tension was measured using a Dunui surface tension tester (Ito Seisakusho Co., Ltd.). The ambient temperature at the time of measurement was 25.8 ° C. and the humidity was 32%. The following measured values of surface tension are average values measured three times.

Table 15 shows the formulation of Comparative Example 1. The formulation of Comparative Example 1 is a formulation obtained by removing the food additive-based surfactant from the attractant formulation 1 shown in Table 1.

The surface tension of the formulation of Comparative Example 1 was 61.0 mN / m. The surface tension of the ion-exchanged water is 72.5 mN / m.

The attractant formulation 12 shown in Table 16 below is a formulation in which Tween 20 is 0.5% by mass with respect to the attractant formulation 1. The attractant formulation 13 is a formulation in which Tween 20 is 0.25% by mass with respect to the attractant formulation 1. The attractant formulation 14 is a formulation in which Tween 20 is 0.10% by mass with respect to the attractant formulation 1. The attractant formulation 15 is a formulation in which Tween 20 is 0.05% by mass with respect to the attractant formulation 1. The attractant formulation 16 is a formulation in which Tween 20 is 0.01% by mass with respect to the attractant formulation 1. The attractant formulation 17 is a formulation in which Tween 80 is 0.5% by mass with respect to the attractant formulation 1. Table 16 shows the surface tensions of the attractant formulations 12 to 17.

As shown in Table 16, the surface tension of the attractant 13 can be significantly reduced as compared with the formulation of the comparative example by adding the surfactant. Then, when the test insects (bees and cockroaches) were added to Comparative Example 1 (excluding the food additive-based surfactant), it was observed that the test insects (bees and cockroaches) continued to rampage and escape for more than 5 minutes. When the test insects were added to the attractant formulations 12 to 17 containing the system surfactant, they stopped their behavior within 3 minutes and floated on the surface of the water. By adding a surfactant in this way to reduce the surface tension, the behavior of insects can be stopped, so that escape from the trapping container 10 can be prevented and the catching effect can be improved. The mechanism by which the decrease in surface tension leads to behavioral arrest has not been fully clarified, but it is thought to be as follows. That is, by lowering the surface tension of the attractant 13, the attractant 13 easily adheres to the insect body and the wings, so that the wings and the body become heavy and cannot fly off from the liquid surface. Then, while the insect is rampaging on the liquid surface, the attractant 13 attached to the insect body closes the airway and chokes. As described above, when the bees attracted by the attractant 13 fall on the liquid surface of the attractant 13, the surface tension of the liquid surface is lowered by the surfactant, so that the bees on the liquid surface cannot escape. Therefore, it can be said that the surfactant added to the attractant 13 is an escape prevention component.

(Capture test)
Next, the capture test of the bee trap 1 will be described. The test method is to install a bee trap 1 in a forest in the Chugoku region and leave it for 3 weeks. The time is summer. The bee trap 1 was collected and the number of bees captured was counted. The n number is 2.

Comparative Example 2 is a bee trap without a collision plate and a cover member, and other parts are the same as those in the above embodiment. Comparative Example 3 is a bee trap in which the colors of the first collision plate and the second collision plate are black, and other parts are the same as those in the above embodiment. In the embodiment, the first collision plate and the second collision plate are colorless and transparent, and the lid is black. The attractants of Comparative Examples 2 and 3 and Examples are the same.

As shown in Table 17, in Comparative Example 3 provided with the black collision plate, no significant difference in the number of catches was observed from Comparative Example 2 without the collision plate. On the other hand, in the example provided with the colorless and transparent collision plate, the number of catches was three times that of Comparative Example 3, and it can be seen that the collision plate brings about a remarkable improvement in the catching effect. The colors of the first collision plate and the second collision plate need only have a large difference from the color of the lid, and the same effect can be obtained even if they are translucent, for example. Further, the same effect can be obtained regardless of whether the lid color is brown, blue, dark blue, or green.

(Action and effect of the embodiment)
As described above, according to this embodiment, the bees around the capture container 10 are attracted by the attractant 13 housed inside the capture container 10 and are captured by entering the capture container 10 through the introduction hole 12a. At the same time, when a bee flying around the capture container 10 collides with the first collision plate 20 and the second collision plate 30 and falls, the bee enters the capture container 10 through the introduction hole 12a and is captured. Since the bee collision surface of the first collision plate 20 and the bee collision surface of the second collision plate 30 face different directions, the bees flying from any direction can be moved to the first collision plate 20 or the second collision plate 30. It will collide.

Not only these things, but also because the visible light transmittance of the upper part of the capture container 10 is lower than the visible light transmittance of the first collision plate 20 and the second collision plate 30, the collision plates 20 and 30 are better than the capture container 10. It looks relatively brighter than the upper part of the container 10, and the bees around the capture container 10 are more likely to fly toward the brighter side, that is, toward the collision plates 20 and 30. As a result, the bee easily collides with the first collision plate 20 or the second collision plate 30, and the bee that has collided with the first collision plate 20 or the second collision plate 30 and falls into the capture container 10 through the introduction hole 12a. Will be captured. Since the bees that collide with the first collision plate 20 or the second collision plate 30 also include the bees attracted by the attractant 13, in addition to the attraction effect of the attractant, the collision plates 20 and 30 and the capture container 10 The attraction effect due to the difference in color from the upper part also occurs, and the capture effect is improved.

In addition, the sugar contained in the attractant 13 is fermented by the action of yeast, so that the bee attracting effect can be enhanced. When the attracted bees fall on the liquid surface of the attractant 13, the surface tension of the liquid surface is lowered by the surfactant, so that the bees on the liquid surface sink into the liquid at an early stage and are difficult to escape from the capture container 10. Become. Since the surfactant is a food additive type, it does not have an adverse effect on yeast fermentation, and it is possible to quickly start fermentation by yeast at the start of use, and a high attraction effect is obtained over a long period of time. Be done.

When the bee catcher 1 is displayed and sold at a store, the first collision plate 20, the second collision plate 30, and the cover member 40 are removed from the capture container 10 and curved between the capture container 10 and the box 100. By accommodating in this state, the space between the capture container 10 and the box 100 can be used as an accommodation space for the collision plates 20, 30 and the cover member 40. As a result, the capture container 10, the collision plates 20, 30 and the cover member 40 can be compactly housed in the box 100, and the box 100 can be miniaturized.

The above embodiments are merely exemplary in all respects and should not be construed in a limited way. Furthermore, all modifications and modifications that fall within the equivalent scope of the claims are within the scope of the present invention. The bees that can be captured by the bee trap according to the present embodiment are not limited to the giant hornet, and other bees can also be captured.

The insect trap of the present embodiment is useful not only for bees but also for catching flying beetles and the like.

As described above, the present invention can be used for capturing bees such as wasps.
