Description

The present invention relates to a liquid absorbing member and a bee control container provided with the liquid absorbing member.

Conventionally, various dietary tools for feeding pests with a liquid diet containing an insecticide or the like have been proposed.

For example, in Patent Document 1, a support lid (3) is fitted into an opening of a container (1) containing an insecticide, and a cloth (4) is coated on the upper surface of the support lid (3) to cover a cloth-covered surface. Insecticide tools for pests (flies, etc.) that formed (5) are described. The lower part of the cloth (4) is immersed in the insecticidal liquid, and the insecticidal liquid permeates to the cloth covering surface (5) due to the capillary phenomenon, so that the cloth covering surface (5) is moistened with the insecticide liquid. Become. According to Patent Document 1, pests can be easily exterminated only by placing an insecticidal tool containing a cloth impregnated with the insecticidal liquid in a room or the like.

Jikkaisho 50-87069

In the insecticide of Patent Document 1, the cloth-covered surface (5) is moistened with the insecticide solution at the beginning of use, but after a certain period of time has passed after the insecticide is placed, the cloth-covered surface (5) is covered. The impregnated insecticide may volatilize and the cloth covering surface (5) (hereinafter, also referred to as the surface of the cloth) may not hold a sufficient amount of the insecticide for the pests to eat. As described above, if the insecticidal liquid impregnated on the surface of the cloth volatilizes, there is a possibility that the period during which the insecticidal liquid effectively functions as a dietary tool is shortened in the conventional configuration.

Therefore, an object of the present invention is to provide a liquid-absorbent member capable of extending the effective period as a dietary tool and a bee control container provided with the liquid-absorbing member.

The liquid-absorbent member according to one aspect of the present invention is a liquid-absorbent member impregnated with a liquid dietary agent for bees to eat, and a recess is formed on the upper side of the liquid-absorbing member main body, and the recess is formed. , It has an opening shape for the bee to enter inside.

According to the above aspect, since the recess having an opening shape for the bee to enter is formed on the upper side (surface side) of the liquid absorbing member main body, the inside of the recess is the upper side (surface side). In comparison, it is difficult for wind from the outside to hit, and it is possible to make it difficult for the inside of the recess to dry. Therefore, even if the upper side of the liquid-absorbing member main body dries after a lapse of a certain period of time, the liquid diet contained in the recess is suppressed from drying, so that the bee can continuously eat the liquid diet. .. By using such a liquid-absorbing member, the bee can eat the liquid diet even after the liquid-absorbing member is placed in a predetermined place for a certain period of time, so that it is effective as a dietary tool. The period can be extended.

In the above aspect, the recess may be formed so as to extend in the direction from the upper side to the lower side of the liquid absorbing member main body.

The bee control container according to one aspect of the present invention includes a liquid-absorbent member and a container body for accommodating the liquid-absorbent member.

The container body of the bee control container according to one aspect of the present invention is provided with an opening at the top, and engages with the lower container for accommodating the food material for bees to eat inside and the opening of the lower container. An inner lid with a bee entrance and exit that communicates with the inside of the lower container and an umbrella body that covers the upper part of the bee entrance and exit are provided, and the inner lid has an inclined surface that increases in height toward the bee entrance and exit. Will be done. The dietary agent stored in the lower container is not limited to the liquid-absorbent member shown in the present embodiment, and may be, for example, a liquid, gel-like, or water-absorbent polymer-like dietary agent.

Here, in a plan view of the container body viewed from above, it is preferable that a part of the inclined surface is extended so as to project to the outside of the umbrella body. The inclination angle of the inclined surface is preferably 1 degree or more and 80 degrees or less. The length of the inclined surface, that is, the distance from the outer edge of the inclined surface to the bee entrance / exit is preferably 10 mm or more and 70 mm or less.

The umbrella body is formed by engaging with the inner lid or being integrated with the inner lid. The umbrella body can be provided with, for example, an arched opening for the bees to enter the inside of the container body. However, if it has an opening that communicates the bee entrance and the outside, its shape and size can be transformed into various things. The arched opening includes both ends connecting to the inner lid and an arch connecting both ends. The arch portion includes a portion formed in a semicircular or curved shape. Further, it is preferable that the arch portion is provided so as to have the largest distance from the inner lid in the vicinity of the middle of both end portions. The distance between the inner lid and the arch portion provided above the inner lid is preferably 10 mm or more and 35 mm or less. Further, it is preferable to provide the inclined surface and the umbrella body so that the distance between the inclined surface and the umbrella body provided above the inclined surface is 10 mm or more.

According to the present invention, it is possible to provide a liquid-absorbing member capable of extending the effective period as a dietary tool and a bee control container provided with the liquid-absorbing member.

Preferred embodiments of the present invention will be described with reference to the accompanying drawings. The dimensions, shape, angle, etc. of the drawings may differ from the actual dimensions, shape, angle, etc. Therefore, the technical scope of the present invention is not limited to the dimensions, shapes, angles, etc. of each part shown in these drawings. For convenience of explanation, when referring to directions such as up, down, left, and right, the description in the drawing is used as a reference. As the pests targeted by the liquid-absorbing member and the bee control container provided with the liquid-absorbing member according to the present embodiment, it is particularly preferable to use it for bees such as wasps and paper wasps.

The configuration of the bee control container 1 according to the present embodiment will be described with reference to FIGS. 1 to 4. FIG. 1 is a perspective view showing a bee control container 1 according to the present embodiment. FIG. 2 is an exploded perspective view of the bee control container 1 excluding the liquid absorbing member 40. FIG. 3 is a perspective view showing a state in which the inner lid 20 and the umbrella 30 of the bee control container 1 shown in FIG. 1 are removed. FIG. 4 is a diagram showing a liquid absorbing member 40.

As shown in FIGS. 1 to 4, the bee control container 1 according to the present embodiment includes a lower container 10 (container body), an inner lid 20, an umbrella 30, and a liquid absorbing member 40. In the bee control container 1, the liquid diet impregnated in the liquid absorbing member 40 stored in the lower container 10 is brought back to the nest by the bees that have invaded the inside, and the liquid diet contains an insecticidal component. In some cases, the effect of poison bait can be obtained in the nest.

As shown in FIGS. 2 and 3, the lower container 10 is provided with an opening 105 at the upper side, and has an accommodating portion for accommodating the liquid absorbing member 40 inside. The accommodating portion indicates a portion surrounded by the inner wall of the lower container 10. The inner wall of the lower container 10 indicates a wall surface (bottom surface 101 and side surface 102 shown in FIG. 2) that is in contact with the inside of the lower container 10 and the space communicating with the opening 105. The lower container 10 is provided with a protrusion 103 extending in a direction perpendicular to the bottom surface 101 at the center of the bottom surface 101. As shown in FIG. 3, the protrusion 103 is inserted into a hole 42 formed at substantially the center of the liquid absorbing member 40 when the liquid absorbing member 40 is housed in the lower container 10, and the protrusion 103 is inserted into the hole 42 formed in the substantially center of the liquid absorbing member 40 to absorb the liquid in the lower container 10. The arrangement of the sex member 40 is fixed.

In the present embodiment, the lower container 10 is formed in a conical trapezoidal shape whose diameter increases toward the upper side, but the shape is not limited to this. The lower container 10 can be changed to various other shapes and sizes as long as it has a function of accommodating the liquid absorbing member 40 inside.

The inner lid 20 is configured to engage with the opening 105 opened above the lower container 10 and to be fixed to the lower container 10. The inner lid 20 is formed in a substantially annular shape in a plan view. A bee entrance 21 (opening) communicating with the lower container 10 is formed in the center of the inner lid 20. Further, the inner lid 20 is formed with a bee retention port 22 for the bees to anchor. The bee-retaining port 22 is inclined so that the inside is higher than the outer edge thereof (the height is increased from the outer edge of the bee-retaining port 22 toward the center side). Further, the bee retention port 22 is formed so as to project radially outward from the outer peripheral surface of the lower container 10. By providing the bee retention port 22 so as to project in this way, the bee can be easily anchored, and the bee can enter the inside of the lower container 10 through the bee entrance / exit 21 formed in the center of the inner lid 20. A plurality of engaging hole portions 23 for engaging the lower end of the umbrella 30 (lower end of the side wall portion 32) are formed in the peripheral portion of the inner lid 20.

In the present embodiment, the inner lid 20 has a flat plate shape, and the outer edge thereof has a substantially circular shape, but the present invention is not limited to this embodiment. Further, the inner lid 20 is provided with one bee entrance / exit 21 and four bee retention ports 22 described above, but the number, shape, and the like thereof are not limited to the illustrated modes. That is, if the inner lid 20 has an opening that communicates with the lower container 10 and is provided with a port for the bees to stay, the number, shape, and the like can be transformed into various things. ..

The umbrella 30 is engaged with the inner lid 20 so as to cover the upper part of the bee doorway 21. When the umbrella 30 is engaged with the inner lid 20, the liquid absorbing member 40 exposed to the outside through the bee entrance / exit 21 is the umbrella 3.
It is covered from the upper side by 0, and it is possible to prevent water or the like (for example, rain) from directly hitting the liquid absorbing member 40 from the outside. The umbrella 30 is provided with an arch-shaped opening 31 that communicates the bee entrance 21 and the outside of the bee control container 1. The arch-shaped opening 31 has a shape that opens in a substantially semicircular shape at the portion where the bee retention port 22 is provided. The bees anchored at the bee retention port 22 can enter the inside of the bee control container 1 (inside the umbrella 30) through the arch-shaped opening 31, and further enter the inside of the lower container 10 through the bee entrance 21. The side wall portions 32 located on both sides of the arch-shaped opening 31 engage with the inner lid 20, and the umbrella 30 and the inner lid 20 are fixed. Specifically, the inner wall of the side wall portion 32 of the umbrella 30 is provided with a guide wall (not shown) extending in the direction from the inner wall toward the bottom surface 101, and is provided at the lower end of the guide wall. The umbrella 30 and the inner lid 20 are fixed by engaging the portion with the engaging hole portion 23 formed so as to penetrate the inner lid 20. The upper surface of the umbrella 30 is provided with a hooking portion 35 for hooking and arranging the bee control container 1 on an external member.

In the present embodiment, the umbrella 30 is provided with four arched openings 31 and four engaging holes 23, respectively, but the present invention is not limited to this embodiment. That is, as described above, if the umbrella 30 suppresses water or the like (for example, rain) from hitting the liquid absorbing member 40 from the outside and has an opening for communicating the bee entrance / exit 21 and the outside, the umbrella 30 has an opening. It is possible to transform its shape, size, etc. into various things.

The liquid-absorbent member 40 is an impregnated body impregnated with a liquid dietary agent for bees to eat. The impregnated body is a porous material that absorbs the liquid diet by capillarity (for example, when the lower part of the porous material is immersed in the liquid diet, the liquid diet penetrates to the upper part of the porous material by the capillary phenomenon). For example, a non-woven fabric, a sponge, or the like is used.

The liquid-absorbent member 40 extends in the direction from the upper surface 40a side to the lower surface 40b side (downward in FIG. 4B) of the main body portion (liquid-absorbent member main body) having a substantially circular plate shape in a plan view. A hole 42 (recess) is formed. The hole 42 may be provided in a region excluding the peripheral edge portion 40c of the liquid absorbing member 40 in a plan view (FIG. 4A). At least one hole 42 may be provided in the liquid absorbing member 40. For example, as shown in FIG. 4A, the hole 42 is formed in the central portion of the liquid absorbing member 40 and around the central portion thereof. In, a plurality of them may be provided at predetermined intervals in the circumferential direction. As shown in FIG. 4, the hole 42 is not limited to the mode formed only in the liquid absorbing member 40, and may be formed between the liquid absorbing member 40 and the lower container 10, for example, and may be formed below. It may be formed only in the container 10. When the hole 42 is formed only in the lower container 10, if the hole 42 is formed along the peripheral edge of the liquid absorbing member 40, the bee that has entered the inside of the hole 42 impregnates the liquid absorbing member 40. It is suitable because the liquid dietary agent can be eaten.

The hole 42 has an opening shape for the bee to enter the inside thereof, in other words, an opening for the bee's head to enter the inside. Specifically, the diameter D of the hole 42 (FIG. 4 (A)) is preferably in the range of 5 to 30 mm. If the diameter D of the hole 42 is larger than 30 mm, the inside of the hole 42 tends to dry, and if the diameter D of the hole 42 is smaller than 5 mm, it becomes difficult for the bee's head to enter the inside of the hole 42. By setting, the bee's head can enter the inside of the hole 42, and the wind or the like is less likely to hit the inside of the hole 42, so that drying can be suppressed. Bees have a habit of poking their necks into their burrows (for example, wasps and paper wasps poke their heads into their burrows to get nutrients by mouth from larvae in their burrows (thick liquid collects below the burrow 42). In this case, wasps and paper wasps have a habit of sticking their heads and licking the liquid below the hole 42), so bees eat the liquid diet contained inside the hole 42 by utilizing this habit. Therefore, even if the upper surface 40a side of the liquid-absorbent member 40 is dried, the liquid dietary agent held inside the hole 42 formed in the liquid-absorbent member 40 is used to utilize the bee's habit. Because it eats, the effective period as a dietary tool can be extended.

The hole 42 is formed so as to extend from the upper surface 40a side of the liquid absorbing member 40 toward the lower surface 40b side. In the present embodiment, the hole 42 formed so as to communicate the upper surface 40a and the lower surface 40b is formed in the liquid absorbing member 40. As shown in FIG. 4B, the extending direction in which the hole 42 extends includes not only the direction from the upper surface 40a side to the lower surface 40b side (vertical direction) but also an arbitrary direction. For example, the extending direction of the hole 42 may be different for each hole 42.

In the illustrated example, the liquid-absorbent member 40 is a mode in which a hole 42 is provided in a main body portion formed in a plate shape (substantially columnar shape) having a substantially circular shape in a plan view, but the present invention is not limited to this mode. That is, the liquid absorbing member 40 can be deformed into various other modes as long as it has a function of holding the liquid, and may be, for example, a sphere or a rectangular shape in a plan view.

Further, in the present embodiment, the upper side or the upper surface side of the liquid absorbing member 40 is the opening 105 (see FIG. 3 etc.) side of the lower container 10 when the liquid absorbing member 40 is installed in the lower container 10. It means a portion exposed to the surface or the periphery of the exposed surface (around the upper surface 40a in FIG. 4B).

In the present embodiment, the hole 42 formed in the liquid absorbing member 40 has a shape penetrating from the upper surface 40a side to the lower surface 40b side of the liquid absorbing member 40, but is not limited thereto. That is, the hole 42 does not have to penetrate the liquid absorbing member 40 as long as it has an opening large enough to accommodate the head of a bee, and is not limited to the shape and size shown in the figure, and may have various shapes. It can be changed to a size. For example, the hole 42 may be a recess having a shape recessed from the upper surface 40a side of the liquid absorbing member 40. The depth from the upper surface 40a of such a recess is arbitrary, but when it is at least half the thickness t (FIG. 4B) of the liquid absorbing member 40, it is compared with the upper surface 40a side which is relatively easy to dry. This is suitable because the bee can eat the liquid dietary agent contained on the lower surface 40b side, which is difficult to dry.

The material of the liquid dietary agent impregnated in the liquid-absorbing member 40 described above is not particularly limited, but for example, an attractant for attracting pests may be blended. Conventionally used attractants can be widely adopted. For example, dietary components such as sugars (granulated sugar, fructose, maltose, trehalose, etc.), proteins, carbohydrates, lipids, etc .: derived from natural substances and Formulated aromatic components, pheromones, amino acids, nucleic acids, fats and oils and the like can be used as active ingredients. These attractants can be used alone or in admixture of two or more.

The impregnation amount of the liquid dietary agent is not particularly limited, but for example, the liquid absorbing member can be impregnated with 0.5 to 4 g / cm3. From the viewpoint of bee attracting effect, it is preferable to impregnate the liquid absorbing member with a saturated amount.

The liquid dietary agent can be used as a liquid poisonous dietary agent by containing an insecticidal component. Examples of the above-mentioned insecticide components include pyrethroid insecticides such as allethrin, tetramesrin, resmethrin, phenothrin, flamethrin, permethrin, ciphenotrin, cypermethrin, tralomesulin, empentrin, prarethrin, etofenprox, and shirafluofen, phenithion, and phenithione. Organic phosphorus insecticides such as hoxime, acephate, pyridafenthion, diazinone, malathion, prothiophos, propetanphos, chlorpyrifos, chlorpyrifos methyl, DDVP, carbamate insecticides such as NAC, penthiocarb, propoxul, other imidaclobrid, metoxadiazone, fipronil , Boric acid, hydramethylnone, lithium sulfonate, lithium perfluorooctasulfonate, sulfulamide, 1-methyl-2-nitro-3,3-tetrahydrofurylmethylguanidine and the like. These can be used alone or in combination.

Hereinafter, the present invention will be described with reference to specific examples. The following examples are merely examples to assist in understanding the present invention, and the scope of the present invention is not limited thereto.

[Example]
(1) Specimen

As a sample (liquid absorbing member), a non-woven fabric having a length of 5 cm, a width of 5 cm, and a thickness of 1 cm is formed with four through holes (holes formed by communicating the upper surface and the lower surface of the sample) having a diameter of 1.3 cm. Using. This sample was impregnated with 40 g of 80% honey water as a liquid diet.
(2) Test insect

As a test insect, Vespa simillima was used.
(3) Test method

The sample of (1) above was placed on a tree in a park where Vespa simillima is located, and it was confirmed whether the test insect of (2) above would eat. Then, the sample of the above (1) was placed on concrete not exposed to rain for one week. After that, a sample was placed on a tree in a park where Vespa simillima is located, and it was confirmed whether or not the test insect of (2) above would eat.
(4) Result

The test results are shown in Table 1. 〇 shown in Table 1 indicates that the test insect ate, and × shown in Table 1 indicates that the test insect did not eat. As a result of observing how the test insects are eating, if a through hole is formed in the sample (1) above, the inside of the sample (lower part of the sample) is provided by putting the head in the through hole. The test insect was eating. From the results shown in Table 1, it was possible to confirm the eating of the test insects regardless of the presence or absence of the through-holes in the sample at the initial stage, but after one week, the eating of the test insects could be confirmed only when the through-holes were formed in the sample. Therefore, it was verified that the effective period can be extended by forming a through hole. In addition, the test insect rides on the sample and puts its head in the through hole to eat a part of the sample. Therefore, when the test insect eats, the liquid dietary agent adheres to the leg and head surface of the test insect. When such a test insect returns to the nest, it becomes possible for other bees to eat the liquid dietary agent adhering to the surface of the test insect. Therefore, when the liquid diet contains an insecticidal component, it is possible to increase the amount of the insecticidal component brought into the nest and enhance the effect of the poison bait in the nest.

The embodiments described above are for facilitating the understanding of the present invention, and are not for limiting and interpreting the present invention. Each element included in the above-described embodiment and its arrangement, material, condition, shape, size, and the like are not limited to those exemplified, and can be changed as appropriate.

Next, the bee control container 1 will be described in detail with reference to FIGS. 1 to 5. FIG. 5 is a cross-sectional view of the bee control container 1 cut in a plane passing through the center of two arched openings 31 formed diagonally and the hook 35.

The inventors of the present application have constructed the bee control container 1 so that the bees can easily invade and at the same time the human fingers are less likely to come into contact with the liquid diet. Specifically, the bee control container 1 includes an inner lid 20 and an umbrella 30 (an example of an “umbrella body”) provided above the inner lid 20. Therefore, unless a finger is inserted through the gap between the umbrella 30 and the inner lid 20, a human finger does not touch the liquid absorbing member 40 housed in the lower container 10.

Further, the inner lid 20 is formed with an inclined surface 22A whose height increases toward the bee entrance / exit 21. As shown in FIG. 2, for example, a plurality of inclined surfaces 22A are formed on the inner lid 20. Bees, on the other hand, may be described as having a negative runnability, that is, the property of organisms traveling in the opposite direction of gravity. By providing the inclined surface 22A, it becomes possible to promote walking of bees into the bee control container 1.

Further, by providing the inclined surface 22A, the finger inserted through the gap between the umbrella 30 and the inner lid 20 comes into contact with the inclined surface 22A and is guided obliquely upward. Therefore, it is possible to guide the finger in the direction away from the liquid absorbing member 40 housed in the lower part of the lower container 10. Further, even if the joint of the finger is to be bent, the finger hits the umbrella 30 and becomes difficult to bend, and it becomes possible to make it difficult to touch the liquid absorbing member 40.

Further, by providing the umbrella 30 and the inclined surface 22A, it is possible to prevent water or the like (for example, rain) from entering the lower container 10 and reducing the concentration of the liquid diet impregnated in the liquid absorbing member 40. Becomes possible. Even if water or the like adheres to the inclined surface 22A, it is difficult for water or the like to enter the lower container 10 from the bee entrance / exit 21 due to the inclination of the inclined surface 22A.

Further, by providing the inclined surface 22A, the wind passing through the bee control container 1 is guided upward along the inclined surface 22A. Therefore, it is possible to prevent the wind from directly hitting the liquid absorbing member 40. Therefore, it is possible to suppress fluctuations in the amount of volatilization of the liquid food material impregnated in the liquid-absorbent member 40, and thus to suppress fluctuations in the usable period of the liquid-absorbent member 40.

The bee control container 1 may be configured to store a dietary agent different from that of the liquid absorbing member 40. For example, it may be configured to store a poison bait such as a liquid, a gel, or a water-absorbing polymer. Even in such a case, it is possible to provide a container body of a bee control container that makes it easy for bees to invade and at the same time makes it difficult for human fingers to touch the liquid diet.

The inclination angle α of the inclined surface 22A (FIG. 5), that is, the inclination angle α formed by the horizontal plane and the inclined surface 22A is preferably 1 degree or more and 80 degrees or less, for example. More preferably, it is 5 degrees or more and 60 degrees or less. If the inclination angle is 1 degree or less, water or the like (for example, rain) will enter the lower container 10. Further, if the inclination angle exceeds 80 degrees, it becomes difficult for the bee to land on the inclined surface 22A and climb the inclined surface 22A. For example, in the present embodiment, the inclination angle α is 20 degrees.

Further, as shown in FIGS. 1 and 5, a part of the inclined surface 22A may extend to the outside of the umbrella 30 (an example of the “umbrella body”). With this configuration, it becomes possible for the bees flying around the bee control container 1 to recognize the inclined surface 22A. Therefore, it is possible to promote the bee to land on the inclined surface 22A. As shown in FIG. 5, the distance D6 of the portion of the inclined surface 22A extending to the outside of the umbrella 30 (the portion protruding outward from the umbrella 30 in a plan view) is 2 mm or more. Is preferable. More preferably, it is 7 mm or more. If the distance D6 is shorter than 2 mm, it becomes difficult for the bee to hang the leg, and thus it becomes difficult for the bee to land on the inclined surface 22A. At least a part of the inclined surface 22A may be provided on the surface of the bee retention port 22. For example, in this embodiment, the distance D6 is 10 mm.

The inclined surface 22A may be provided, for example, from the outer edge of the bee stop port 22 to the bee entrance / exit 21. The length of the inclined surface 22A, that is, the distance D4 (FIGS. 2 and 5) from the outer edge of the inclined surface 22A in the radial direction to the bee entrance / exit 21 is preferably 10 mm or more and 70 mm or less, more preferably 20 mm or more and 60 mm. It is as follows. If the distance D4 of the inclined surface 22A is smaller than 10 mm, it becomes difficult for the bee to land on the inclined surface 22A. Further, if the distance D4 of the inclined surface 22A is smaller than 10 mm, the human finger tends to come into contact with the food. Therefore, the length of the inclined surface 22A is preferably 10 mm or more. If the distance D4 of the inclined surface 22A is larger than 70 mm, the bee control container 1 becomes large, so that the installation location of the bee control container 1 is limited. Further, since the average of the second finger length of a person is about 70 mm, it is unlikely that the fingertip touches the liquid absorbing member 40 even if the distance D4 is not made larger than 70 mm. Further, when the distance D4 is increased, the walking distance of the bees landing on the inclined surface 22A is increased, so that the possibility that the bees reach the bee entrance / exit 21 is reduced. For example, in this embodiment, the distance D4 is 25 mm.

The umbrella 30 may include, for example, an arched opening 31 for bees to enter. However, if the bee entrance 21 has an opening that communicates with the outside, the shape, size, and the like can be changed into various shapes. The arch-shaped opening 31 includes both ends connected to the inner lid 20 and an arch portion connecting both ends. The arch portion includes a portion formed in a semicircular or curved shape. Further, the arch portion is provided so that the distance from the inner lid 20 is maximized near the middle of both end portions.

As shown in FIG. 1 and the like, the umbrella 30 includes four arch-shaped openings 31 provided in a 90-degree rotational symmetry with respect to a central axis that vertically penetrates the center of the bee control container 1. Therefore, it is possible to allow the bee to enter the bee control container 1 from all directions. Further, by providing at least two arch-shaped openings 31 in the diagonal direction, it is possible to improve ventilation. Therefore, when the liquid absorbing member 40 is impregnated with an attractant that attracts bees, the wind passing through the bee control container 1 promotes the volatilized attractant to spread around the bee control container 1. Will be possible. Here, the height of the arch-shaped opening 31 with respect to the inclined surface 22A of the inner lid 20 (the vertical distance between the inclined surface 22A and the intermediate portion of the arch-shaped opening 31) is 10 mm or more and 35 mm or less. It is preferably present, and more preferably 10 mm or more and 30 mm or less. When the height of the arch-shaped opening 31 from the inner lid 20 is 10 mm or more, even a large bee such as a wasp can enter the bee control container 1. On the other hand, if the height of the inner lid 20 and the arched opening is larger than 35 mm, the human finger can easily come into contact with the food. In addition, large insects other than bees invade. In the present embodiment, in the vertical cross section shown in FIG. 5, the ceiling surface 30A of the arched opening 31 is provided horizontally, while the inclined surface 22A is inclined. Therefore, the height of the arch-shaped opening 31 with respect to the inclined surface 22A of the inner lid 20 becomes smaller as it approaches the bee entrance / exit 21. As shown in FIG. 5, the height of the arch-shaped opening 31 with respect to the inclined surface 22A is minimized, and the ceiling surface 30A and the vertical direction thereof at the bee entrance 21 side end of the arch-shaped opening 31. By setting the height D1 with the inclined surface 22A to 10 mm or more and 35 mm or less, more preferably 10 mm or more and 30 mm or less, the bees can be easily penetrated into the bee control container 1. On the other hand, the distance between both ends of the arched opening 31 is preferably 10 mm or more and 100 mm or less, and more preferably 15 mm or more and 80 mm or less.

Further, the distance between the inclined surface 22A and the umbrella 30 provided above the inclined surface 22A is preferably maintained at 10 mm or more. With such a configuration, it becomes easy for the bee to walk on the inclined surface 22A and enter the bee control container 1. Therefore, the distance D2 (maximum height difference in the vertical direction) between the inner diameter side end of the inclined surface 22A and the lower surface (inner surface facing downward) of the umbrella 30 is preferably 10 mm or more. For example, in this embodiment, the maximum distance D2 is 20 mm. As described above, the arched opening 31 which is the entrance of the bee may have a ceiling surface 30A (FIG. 5) which is horizontal in the vertical cross section (FIG. 5). When such a ceiling surface 30A is provided, on the other hand, the inclined surface 22A is formed so as to increase in height toward the bee entrance / exit 21, so that the distance between the inclined surface 22A and the umbrella 30 approaches the bee entrance / exit 21. A smaller area is provided. With such a configuration, the movable range of the finger inserted through the gap between the umbrella 30 and the inner lid 20 is limited, and the finger can be easily guided upward along the inclined surface 22A. Even if the structure is other than the arch-shaped opening 31, a ceiling surface that is horizontal in the vertical cross section may be provided at the portion of the umbrella 30 that serves as the entrance for the bee.

The diameter D3 of the bee entrance / exit 21 is preferably 10 mm or more and 140 mm or less, and more preferably 10 mm or more and 100 mm or less. If the diameter D3 is smaller than 10 mm, it becomes difficult for bees to enter. Therefore, the diameter D3 of the bee entrance / exit 21 is preferably at least 10 mm or more. On the other hand, if the diameter D3 is larger than 140 mm, the bee control container 1 becomes large, so that the installation location of the bee control container 1 is limited. Therefore, the diameter D3 of the bee entrance / exit 21 is preferably 140 mm or less. For example, in this embodiment, the diameter D3 is 60 mm.

The line segment L1 shown in FIG. 5 indicates the position of the upper end of the liquid absorbing member 40. The distance D5 (height difference in the vertical direction) between the upper end of the liquid absorbing member 40 and the inner diameter side end of the inclined surface 22A is preferably 1 mm or more and 45 mm or less, and more preferably 10 mm or more and 40 mm or less. When the interval D5 is made smaller than 1 mm, the liquid-absorbent member 40 is easily exposed to the wind passing through the bee control container 1, and thus the drying of the liquid-absorbent member 40 is promoted. Further, when the knuckles are bent, the fingertips easily touch the liquid absorbing member 40. By setting the interval D5 to 1 mm or more, it is possible to realize a structure in which drying of the liquid absorbing member 40 is suppressed and it is difficult for a person's fingertip to touch the liquid absorbing member 40. On the other hand, if the interval D5 is larger than 45 mm, it becomes difficult for the bee to escape. For example, in this embodiment, the spacing D5 is 15 mm.

Further, the length of the inclined surface 22A, that is, the distance D4 from the outer edge of the inclined surface 22A in the radial direction to the bee entrance / exit 21, and the end point of the inclined surface 22A, that is, the inner diameter side end portion of the inclined surface 22A and the liquid absorbing member. The sum of the distance D5 from 40 is preferably 20 mm or more, more preferably 30 mm or more. When the sum of the distance D4 and the distance D5 is smaller than 20 mm, the fingertips easily touch the liquid absorbing member 40. For example, in this embodiment, the sum of the distance D4 and the distance D5 is 40 mm.

Further, as shown in FIG. 2, a groove G extending in the radial direction may be provided between the adjacent inclined surfaces 22A. With such a configuration, the bee can hook the leg, and thus it becomes possible to assist the bee to climb the inclined surface 22A. The inclined surface 22A may be provided with a convex portion or an uneven portion.

Further, the angle β (FIG. 5) between the straight line connecting the tip of the umbrella 30 (the end in the outer diameter direction of the arched opening 31) and the inner diameter side end of the inclined surface 22A and the horizontal plane is 1 degree or more and 80 degrees or less. It is preferably 30 degrees or more and 60 degrees or less. When the angle β is smaller than 1 degree, it is difficult to confirm that the bee is inside the bee control container 1. Therefore, it was found that if a finger is accidentally inserted, there is a risk of being stung by a bee. On the other hand, when the angle β is larger than 80 degrees, rain easily invades. For example, in this embodiment, the angle β is 45 degrees.
