Description

The present invention relates to a flying insect trap that attracts and traps flying insects.

For the purpose of controlling flying pests such as flies, various flying pest traps with an attractant inside are commercially available. In order to efficiently attract flying pests to a flying pest trap, it is necessary to devise the structure of the flying pest trap and the attractant to be used.

Conventionally, in order to allow flying pests attracted by an attractant to enter the inside of the trap, there has been a catcher provided with a ventilation opening with a difference in height from the entrance for the entry of flying pests (for example, see Patent Document 1). reference). The catcher of Patent Document 1 has a dome-shaped upper portion with a flat curved surface, and an entrance is provided on the curved surface of the dome portion. As a result, insect pests attracted to the vicinity of the entrance can be attracted to the inside of the container without remaining on the surface of the dome portion and captured.

Also known is a trap that has a square-shaped protruding part that protrudes upward from a container to perch on flying pests (see, for example, Patent Document 2). According to Patent Document 2, an opening through which flying pests enter is provided on the side of the protruding portion, and flying pests that have gathered and perched on the protruding portion can be lured into the container through the opening. .

Japanese Patent Application Laid-Open No. 2002-171889 Japanese Unexamined Patent Application Publication No. 2010-57502

However, in reality, flying pests do not always enter the container smoothly through the entrance (opening), and may continue to fly in irregular trajectories. In addition, since the flying pests do not always stay near the trap, it is difficult to effectively act on the attractant that volatilizes from the entrance. Therefore, when catching flying pests, it is easier to control the behavior of flying pests by actively stopping them on some object rather than allowing them to fly freely. By doing so, it is believed that the attracting component that volatilizes from the inside of the container to the outside can reliably act on the flying pests and attract them to the inside of the container.

In this regard, since the trap of Patent Document 1 has a flat curved surface on the outer side as described above, it is difficult for flying pests to stop on the outer surface of the trap. Therefore, unless the flying pest that has approached the trap due to the attracting component smoothly enters the container as it is, it cannot be caught.

On the other hand, the catcher of Patent Document 2 is provided with a projecting portion for stopping flying pests. The projecting portion is formed by bulging a portion of the lid upward to expose it in a rectangular shape. Even if flying pests stop, the projecting part having such a square shape is likely to be alerted because it is largely exposed to the surroundings, and there is a risk that the flying pests will escape from the projecting part when they feel the presence of people. be. Moreover, in this trap, the protrusion and the opening provided on the side thereof are not properly arranged, and the distance between them is relatively large. It's also not easy to move.

As described above, the current traps have much room for improvement in terms of guiding the flying pests that have landed on the outer surface of the container into the inside of the container to reliably trap them. The present invention has been made in view of the above problems, and has an excellent attracting effect against flying pests, especially flying pests represented by fruit flies such as fruit flies, flea flies, blackfly flies, mushroom flies, and moth flies. and to provide a flying pest trap exhibiting a trapping effect.

The characteristic configuration of the flying insect trap according to the present invention for solving the above problems is as follows:
A flying insect trap that attracts and traps flying insects,
an adhesive sheet to which the flying pest adheres;
a main body on which the adhesive sheet is installed;
a cover portion attached so as to cover the adhesive sheet;
an entry hole provided in the cover portion through which the flying pest enters;
with
When the cover portion is attached to the main body, an internal space for containing the adhesive sheet is formed between the main body and the cover portion, and the flying pest inhabits the internal space through the entrance. configured to communicate with an external environment that
An edge portion for guiding flying pests landed on the outer surface of the cover portion to the entrance is provided in the vicinity of the entrance of the cover portion.

According to the flying pest trap of this configuration, the edge portion provided near the entry port functions to guide the flying pests perched on the outer surface of the cover portion to the entry port. When the insect is attracted to the vicinity of the trap and stops on the outer surface of the cover, the flying insect can easily enter the internal space through the entrance through the edge, and can be captured with a high probability.

In the flying insect trap according to the present invention,
Preferably, said edge portion comprises an annular edge portion formed to surround the contour of said entry port.

According to the flying insect trap of this configuration, since the annular edge portion is formed so as to surround the entrance, when the flying insects perched on the outer surface of the cover portion reach the location of the annular edge portion, It becomes easier for them to enter the inside of the flying insect trap through the entrance. As a result, flying pests can be captured with high probability.

In the flying insect trap according to the present invention,
Preferably, the edge portion further includes a linear edge portion formed parallel to the outline of the entrance.

According to the flying pest trap of this configuration, the linear edge portion is formed so as to be parallel to the outline of the entry opening, so that the flying pests that perch on the outer surface of the cover portion can be caught by the linear edge portion. Once the position is reached, they are less likely to move away from the entry opening and are more likely to enter the interior of the flying insect trap through the entry opening.

In the flying insect trap according to the present invention,
It is preferable that the adhesive sheet includes a UV absorbing portion that absorbs ultraviolet light having a wavelength sensitive to the flying pest, and a UV reflecting portion that reflects the ultraviolet light.

According to the flying pest trap of this configuration, the ultraviolet light is absorbed by the UV absorbing portion and reflected by the UV reflecting portion, so that the reflected light of the ultraviolet light produces a bright and dark pattern with strong contrast on the adhesive sheet. Flying pests such as flies have photoreceptor cells that are highly sensitive to ultraviolet rays, and detect changes in brightness with compound eyes that have a wide field of view. can give As a result, flying pests can be effectively attracted and captured.

In the flying insect trap according to the present invention,
In the pressure-sensitive adhesive sheet, it is preferable that the UV absorbing portion and the UV reflecting portion are rectangular and arranged in a checkered pattern.

According to the flying insect trap of this configuration, since the light and dark pattern of the reflected ultraviolet light is generated on the adhesive sheet in a checkered pattern, the flying insect is attracted to the vicinity of the flying insect trap, and only a part of the adhesive sheet is covered. Even when the object is captured within the compound eye field of view, it is possible to appropriately provide an attractive stimulus by the bright and dark pattern of the reflected ultraviolet light. As a result, the flying pests attracted to the vicinity of the flying pest trap can be reliably guided into the internal space and efficiently captured.

In the flying insect trap according to the present invention,
In the pressure-sensitive adhesive sheet, it is preferable that the UV absorbing portion is colored with hue numbers 7 to 9 on the PCCS hue circle, and the UV reflecting portion is colored with hue numbers 4 to 6 on the PCCS hue circle.

According to the flying pest trap of this configuration, the preferred combination of hues described above is selected as the color scheme of the UV absorbing portion and the UV reflecting portion of the adhesive sheet, so that the flying pests that approach the trap are adhered. It can be reliably attracted to the internal space where the sheet is installed and captured.

In the flying insect trap according to the present invention,
It is preferable to further include a chemical part that volatilizes the fragrant component derived from the plant that attracts flying insects.

According to the flying pest trap of this configuration, by including the drug portion containing the fragrant component (attractant) derived from the plant that attracts flying pests, the UV absorbing portion and the UV reflecting portion reduce the amount of reflected ultraviolet light generated on the adhesive sheet. Together with the light and dark pattern, it is possible to synergistically attract flying pests.

In the flying insect trap according to the present invention,
It is preferable that the drug portion is arranged near the center of the cover portion, and that a plurality of entrance ports are arranged around the drug portion.

According to the flying pest trap of this configuration, since a plurality of entrances are arranged around the drug part, the fragrant component (attractant) derived from the flying pest-attracting plant is evenly volatilized from the entrances, and the flying pest attracts the flying pests. can be induced.

In the flying insect trap according to the present invention,
The flying insect-attracting plant is preferably a plant of the subfamily Araceae.

According to the flying pest trap of this configuration, since the attractant contains the scent component derived from the insect-pollinated plant of the Araceae family, which attracts the flying pest, the attracting effect on the flying pest is extremely high. An excellent flying insect trap can be provided.

FIG. 2 is an explanatory diagram of the assembly procedure of the flying insect trap according to the embodiment. FIG. 3 is a cross-sectional view of the flying insect trap along line AA in FIG. 1(b). FIG. 4 is a cross-sectional view of the flying insect trap along line BB in FIG. 1(b). FIG. 5 is an image diagram illustrating the arrangement of the UV absorbing portion and the UV reflecting portion on the adhesive sheet.

Flying pest traps that capture flying pests, such as flies, realize a state that attracts the interest of the target flying pests (for example, a container shape that makes it easy for flying pests to stop, volatilization of attracting ingredients that flying pests like, etc.). By doing so, the flying pests are drawn to the flying pest catcher and captured inside. Such a mechanism also exists in the natural world. For example, carnivorous plants that capture insects and use them as a source of nutrition are examples. Carnivorous plants are plants whose leaves and stems have partially developed as insect-trapping organs, and attract insects by the shape of the insect-trapping organs and the odor emanating from them. There are trapping methods for carnivorous plants, such as a pitfall method, an adhesive method, a pinch trap method, and a bag trap method. Among these, for example, nepenthes and saxifrage are known as trap-type carnivorous plants. Nepenthes have a sac-like trapping organ containing digestive juices, and on the surface of the sac, linear projections called wings are formed extending downward from the opening of the sac. It is Insects have a habit of moving along a linear process when they land on it. Therefore, when an insect lands on the surface of the bag of Nepenthes, it moves along the wings to the opening of the bag and falls into the bag from the opening to be captured. In addition, the saxifrage is also equipped with a bag for trapping insects with streak-like linear projections called keel, similar to that of Nepenthes, and insects perched on the keel can be dropped inside the bag and captured.

On the other hand, although not carnivorous plants, there are plants that propagate by attaching pollen to captured insects (sometimes referred to as ``enthusiastic flowers'' or ``trapping plants''). For example, Papillae is a type of plant belonging to the subfamily Araceae, genus Amaranthus, and emits an odor that insects like to attract insects. At this time, since the pollen of the pit viper adheres to the insects, when the insects with the pollen attached take off from the pit viper, they can spread over a wide area.

In insect trapping systems such as carnivorous plants found in the natural world, various devices have been devised for the propagation of the plants, and they function in a rational manner. The present inventors focused on this excellent mechanism of trapping insects of carnivorous plants and the like found in nature, and considered whether it could be applied to a trap for flying insects, and came up with the idea of the present invention. That is, the present invention is a biomimetic type flying pest trap that imitates carnivorous plants, and is a completely new type of insect repellent product that has not existed in the past.

An embodiment of a flying insect trap of the present invention will be described below with reference to FIGS. 1 to 5. FIG. However, the present invention is not intended to be limited to the embodiments described below or the configurations described in the drawings.

[Overall Configuration of Flying Pest Catcher]
FIG. 1 is an explanatory diagram of a usage state of a flying insect trap 100 according to an embodiment of the present invention. FIG. 1(a) is a perspective view of the flying insect trap 100. FIG. FIG. 1(b) is a front view of the flying insect trap 100. FIG. FIG. 2 is an explanatory diagram of the assembly procedure of the flying insect trap 100 according to the embodiment of the present invention. FIG. 2(a) is an exploded perspective view of the flying insect trap 100 in an unfolded state. FIG. 2(b) is a perspective view of the flying insect trap 100 in the process of being assembled. FIG. 2(c) is a perspective view of the assembled flying insect trap 100. FIG.

The flying pest trap 100 is a device that attracts and captures flying pests such as fruit flies (eg, fruit flies, flea flies, black fly flies, mushroom flies, and moth flies) and flies (eg, house flies, blow flies, stink flies, and flesh flies). , and as shown in FIG. 1, it is used in an upright state (for example, in a state of being hung from the edge of the eaves).

The flying insect trap 100 includes a main body 10 and a cover portion 20 attached to the main body 10. - 特許庁As shown in FIG. 2( a ), the main body 10 is formed with a flat planar portion 11 , and an adhesive sheet 30 to which flying pests adhere is placed on the planar portion 11 . In the present invention, the adhesive sheet 30 has one feature, and its configuration will be described in detail in the item "adhesive sheet" below. A body-side joint portion 12 is formed on the front end side of the body 10, and a convex portion 12a provided on the body-side joint portion 12 is aligned with a concave portion 22a provided on a cover-side joint portion 22 of a cover portion 20, which will be described later. By inserting, the main body 10 and the cover part 20 are joined, and the outer shape of the flying insect trap 100 is formed. Supporting portions 13 are provided on both sides of the planar portion 11 in the main body 10 in the width direction. The support portion 13 contributes to the formation of an internal space S of the flying insect trap 100, which will be described later. Furthermore, as shown in FIG. 2(a), the main body 10 is integrally provided with a hook 14. When the hook 14 is bent to the back side of the main body 10, as shown in FIG. It becomes possible to suspend and use the trap 100. - 特許庁It is also possible to use the flying insect trap 100 without bending the hook 14 from the main body 10 .

The cover part 20 is attached to the main body 10 so as to cover the adhesive sheet 30 placed on the main body 10 . The cover portion 20 is provided with an entrance 40 for entry of flying pests. Further, as shown in FIG. 2A, the cover portion 20 is provided with a pressing portion 50 for fixing the adhesive sheet 30 placed on the main body 10 when the cover portion 20 is attached to the main body 10 . The function of the pressing portion 50 will be described in the next item "Assembly of Flying Pest Catcher". Further, the cover portion 20 is provided near the center thereof with a medicine portion 60 for containing an attractant for attracting flying pests. The attractant to be stored in the drug section 60 will be described in detail in the item of "attractant" described later.

A plurality of inlets 40 are arranged around the drug section 60, but in the present embodiment, they are provided separately above and below the drug section 60, as shown in FIG. 1(b). In FIG. 1(b), the entry port 40 includes four upper openings 40a arranged in the width direction of the cover portion 20 on the upper side of the medicine portion 60, and four openings 40a on the lower side of the medicine portion 60. Twenty four lower openings 40b arranged in the width direction and eight openings in total, each opening having an area of 2 to 12 cm ² , preferably 2 to 8 cm ^{2 .} , more preferably 3 to 7 cm ² .

Further, the cover portion 20 is provided with an edge portion 70 . The edge portion 70 is provided near the entrance 40 . The vicinity of the entrance 40 includes not only a position in contact with the edge of the entrance 40 (that is, 0 mm) but also a position that is slightly away from the edge of the entrance 40 (for example, about 0.5 to 2 mm). . In this embodiment, as shown in FIG. 1(b), the edge portion 70 includes an annular edge portion 71 formed so as to surround the outline of the entrance and a line edge portion 71 formed so as to be parallel to the outline of the entrance. and a shaped edge portion 72 .

FIG. 3 is a cross-sectional view of the flying insect trap along line AA in FIG. 1(b). FIG. 4 is a cross-sectional view of the flying insect trap along line BB in FIG. 1(b). Edge portion 70 is formed such that the outer surface of cover portion 20 protrudes outward. The structure of the edge portion 70 imitates the structure found in carnivorous plants and the like, and functions to guide flying pests perched on the outer surface of the cover portion 20 to the entrance 40 . That is, when a flying pest lands on the edge portion 70, the flying pest moves along the edge portion 70 due to its habit. This mimics pitfall-type carnivorous plants such as nepenthes and saxifrage. Due to such a structure, when the flying insects perched on the outer surface of the cover part 20 reach the position where the edge part 70 is located, they are less likely to move away from the entry opening, and the flying insect trap 100 moves away from the entry opening 40. Increased chance of intrusion. 1 and 2 exemplify the edge portion 70 composed of the annular edge portion 71 and the linear edge portion 72, the edge portion 70 is composed only of the annular edge portion 71 or the linear edge portion 72. It is also possible to

The protrusion height of the edge portion 70 from the outer surface of the cover portion 20 is preferably 0.1 to 5 mm, more preferably 1 to 3 mm. If the protrusion height of the edge portion 70 from the outer surface of the cover portion 20 is less than 0.1 mm, the amount of protrusion is insufficient, so that flying pests come off the edge portion 70 during movement and cannot be guided to the entrance 40. There is fear. If the protrusion height of the edge portion 70 from the outer surface of the cover portion 20 exceeds 5 mm, the distance from the upper end portion of the edge portion 70 to the inside of the entrance 40 becomes large, so that flying pests can reach the periphery of the entrance 40. Even if it approaches, there is a possibility that it cannot move to the inside of the flying insect trap 100 . The width of the edge portion 70 is preferably 0.5 to 5 mm, more preferably 1 to 3 mm. When the width of the edge portion 70 is less than 0.5 mm, the insufficient width makes it difficult for flying pests to perch on the edge portion 70 and may not guide them to the entrance 40 . If the width of the edge portion 70 exceeds 5 mm, the flying pest that has landed on the edge portion 70 tends to stay there and may not be guided to the entrance 40 . The edge portion 70 may be chamfered or rounded. In this case, the flying pests that perch on the outer surface of the cover portion 20 can easily climb over the step formed by the edge portion 70, so that especially the flying pests that are lured around the entrance 40 will drop into the entrance 40. It becomes easy and the capture effect can be enhanced.

The main body 10 and the cover portion 20 are made of a material that is excellent in moldability and impermeable to a component that attracts flying insects contained in an attractant, which will be described later. Examples of such materials include resin materials such as polyethylene, polypropylene, polyethylene terephthalate, polybutylene terephthalate, polycarbonate, and polystyrene.

[Assembly of flying insect trap]
Since the flying insect trap 100 is usually sold in a compact or thin packaging form (package), the flying insect trap 100 needs to be taken out of the package and assembled before use. The assembly work of the flying insect trap 100 is performed according to the procedure shown in FIGS. 2(a) to 2(c). Before use, the flying insect trap 100 is in a state in which the cover part 20 is unfolded with respect to the main body 10 . Specifically, as shown in FIG. 2(a), the main body 10 and the cover portion 20 are juxtaposed in the longitudinal direction and hinged at their ends. An adhesive sheet 30 is placed on the planar portion 11 of the main body 10 before assembly. The adhesive sheet 30 has a placement surface (the back surface in FIG. 2(a)) in contact with the planar portion 11 and an adhesive surface (in FIG. 2(a)) coated with an adhesive that adheres to the body of the flying pest. The adhesive surface is protected by release paper (not shown) until just before use. When the adhesive sheet 30 is placed on the planar portion 11, a double-sided tape is adhered to the planar portion 11, and the adhesive sheet 30 is placed thereon. Note that both sides of the adhesive sheet 30 may be configured as adhesive surfaces, and one adhesive surface may be directly attached to the planar portion 11 . After the adhesive sheet 30 is placed on the planar portion 11 , the release paper is peeled off to expose the adhesive surface, and an attractant is injected into the drug portion 60 of the cover portion 20 .

Next, as shown in FIG. 2B, the cover portion 20 is rotated toward the main body 10 and folded. When the attractant injected into the drug portion 60 has fluidity, it is also possible to rotate the main body 10 toward the cover portion 20 so as not to spill the attractant.

Furthermore, as shown in FIG. 2(c), the end of the cover part 20 and the end of the main body 10 are joined together. At this time, although not shown in FIG. 2(c), the convex portion 12a provided in the body-side joint portion 12 of the main body 10 is inserted into the concave portion 22a provided in the cover-side joint portion 22 of the cover portion 20. . Further, in the internal space S, the pressure portion 50 provided on the cover portion 20 presses the surface of the adhesive sheet 30 placed on the main body 10, and the position of the adhesive sheet 30 is fixed. Therefore, it becomes possible to use the flying insect trap 100 in a state of being leaned. In consideration of usability, the surface of the adhesive sheet 30 with which the pressing portion 50 contacts may be a non-adhesive surface on which no adhesive is applied.

The main body 10 is further provided with two supporting portions 13 on both sides of the planar portion 11 in the width direction, and the supporting portions 13 protrude from the main body 10 by about 1.5 to 4 cm. When the cover portion 20 is attached to the main body 10 , the cover portion 20 is supported by the support portion 13 while being curved in a direction away from the main body 10 . , and the curved surface of the cover portion 20 form an internal space S. The internal space S communicates with the external environment inhabited by flying pests through an entrance 40 provided in the cover portion 20 . Here, it is preferable that the support portion 13 is provided so as to be positioned closer to the cover-side joint portion 22 than the center in the longitudinal direction of the cover portion 20 . If the supporting portion 13 is provided in this way, for example, when the flying insect trap 100 is used in an upright position, the top of the curved surface of the cover portion 20 is positioned near the top of the flying insect trap 100 . Since it is conspicuous, it becomes easier for flying pests to enter the internal space S. The internal space S is designed to have a width of 6 to 15 cm, a length of 10 to 20 cm, and a maximum height (distance from the adhesive sheet 30 to the inlet 40) of 1.5 to 4 cm.

As described above, since the flying insect trap 100 can be easily assembled, the packaging form of the product can be simplified. As a result, it can contribute to cost reduction of products.

[Adhesive sheet]
FIG. 5 is an image diagram illustrating the arrangement of the UV absorbing portion and the UV reflecting portion on the adhesive sheet. FIG. 5(a) shows an example in which square UV absorbing portions P and UV reflecting portions Q are arranged in a checkered pattern. FIG. 5(b) shows an example in which rectangular UV absorbing portions P and UV reflecting portions Q are arranged in a checkered pattern. In the present invention, the adhesive sheet 30 not only adheres to the body of the flying pest to capture it, but also has the function of attracting the flying pest to the internal space S of the trap 100 for flying pests. The present inventors conducted various studies on attracting flying insect pests, and found that the adhesive sheet 30 has a UV absorbing portion P that absorbs ultraviolet rays having a wavelength sensitive to flying insect pests and a UV reflecting portion Q that reflects the ultraviolet rays. It was found that by providing a , flying insects can be effectively attracted. The wavelength of the ultraviolet rays absorbed by the UV absorbing portion P and reflected by the UV reflecting portion Q is preferably 200 to 400 nm, more preferably 300 to 380 nm. In such a configuration, ultraviolet rays are absorbed by the UV absorbing portions P and reflected by the UV reflecting portions Q, so that the reflected light of the ultraviolet rays produces a bright and dark pattern with a strong contrast on the adhesive sheet 30 . Flying insect pests such as flies have photoreceptor cells that are highly sensitive to ultraviolet light in the vicinity of a wavelength of 380 nm. It can give a strong attracting stimulus to pests. As a combination of colors attached to the UV absorbing part P and the UV reflecting part Q, the UV absorbing part P is colored with hue numbers 7 (reddish yellow) to 9 (greenish yellow) in the PCCS color wheel, and the UV reflecting part P is colored with hue numbers 7 (reddish yellow) to 9 (greenish yellow) Part Q is preferably colored to hue numbers 4 (reddish orange) to 6 (yellowish orange). The PCCS color wheel is based on the four primary colors of 2 (red), 8 (yellow), 12 (green), and 18 (blue), and 24 hues consisting of these four primary colors and 20 intermediate colors that interpolate the four primary colors. are arranged in an annular shape so that they perceptually shift to the same pace.

When the adhesive sheet 30 is provided with the UV absorbing portion P and the UV reflecting portion Q in this way, the flying pests attracted to the vicinity of the flying pest trap 100 can be reliably guided to the internal space S and efficiently captured. It becomes possible. The flying pest trap 100 of the present embodiment combines the function of attracting and catching flying pests, and exhibits a high synergistic effect.

As shown in FIG. 5, it is preferable that the UV absorbing portion P and the UV reflecting portion Q are configured in a rectangular shape and arranged in a checkered pattern on the adhesive sheet 30 . Here, the "rectangular" does not have to strictly define its shape as long as it is visually rectangular. Therefore, not only geometrically perfect squares or rectangles but also approximately squares or approximately rectangles are included. With such a configuration, the light-dark pattern of the reflected light of the ultraviolet light on the adhesive sheet 30 becomes a checkerboard pattern, and the light-dark pattern of the ultraviolet light is included even when looking at a partial area of the adhesive sheet. Therefore, even when the flying pest attracted to the vicinity of the flying pest trap 100 sees, for example, only the area surrounded by the broken line in FIG. can. As a result, the flying pests attracted to the vicinity of the flying pest trap 100 can be efficiently guided into the internal space S and captured by the adhesive sheet 30 . The UV absorbing portions P and UV reflecting portions Q arranged in a checkered pattern are preferably configured as rectangular portions with the shortest sides of 5 to 50 mm, preferably 10 to 30 mm. If the shortest sides of the UV absorbing portion P and the UV reflecting portion Q are 5 to 50 mm, the flying insects flying apart from the flying insect trap 100 and the flying insects attracted to the vicinity of the flying insect trap 100 are attracted to the outside of the cover portion 20. Any of the flying pests that perched on the surface can capture the bright and dark pattern in the compound eye visual field, and can be given an appropriate attractive stimulus to them. If the shortest sides of the UV absorbing portion P and the UV reflecting portion Q are smaller than 5 mm, it becomes difficult to distinguish the light and dark pattern at a position away from the flying pest trap 100, so that the flying pest attracts the flying pest with the light and dark pattern. may not be able to effectively provide When the shortest sides of the UV absorbing portion P and the UV reflecting portion Q are larger than 50 mm, the flying pest attracted to the vicinity of the flying pest trap 100, especially the flying pest stopped on the outer surface of the cover portion 20, is within the compound eye field of view. However, there is a possibility that only one region of the UV absorbing portion P and the UV reflecting portion Q will be captured, and an attractive stimulus due to the bright and dark pattern cannot be given.

Various variations are conceivable for the checkered pattern. For example, among the rectangular portions forming the UV absorbing portion P and the UV reflecting portion Q, the rectangular portions arranged near the entrance 40 may be configured to be smaller than the rectangular portions arranged at other positions. good. With such a configuration, flying pests flying away from the flying pest trap 100 can easily recognize the bright and dark patterns of the UV absorbing portion P and the UV reflecting portion Q, which are formed of large rectangular portions, and the outer surface of the cover portion 20 can be easily recognized. Flying pests that land on the shore easily perceive the bright and dark pattern of the UV absorbing portion P and the UV reflecting portion Q, which are formed by small rectangular portions in the vicinity of the entrance 40 . As a result, both the flying pests flying apart and the flying pests resting on the outer surface of the cover part 20 are effectively attracted by the bright and dark pattern, and the flying pests are attracted to the inner space S with a high probability. be able to.

Attracted by the bright and dark pattern of the reflected light of the ultraviolet rays of the adhesive sheet 30, the flying insects that enter the internal space S through the inlet 40 of the flying insect trap 100 adhere to the adhesive applied to the base material of the adhesive sheet 30. captured by The adhesive is preferably applied to the surface of the adhesive sheet 30 so as to form unevenness. By applying the adhesive in an uneven manner, the adhesive can be effectively adhered to the flying pests that come into contact with the adhesive. In addition, the adhesive is not particularly limited as long as the light and dark pattern due to the reflected light of the ultraviolet rays in the adhesive sheet 30 can be visually recognized from the adhesive side (that is, as long as it has a certain ultraviolet transmittance). , rubber-based adhesives, acrylic-based adhesives, silicone-based adhesives, and the like can be used. Rubber-based adhesives include natural rubber-based adhesives, styrene/butadiene rubber-based adhesives, recycled rubber-based adhesives, polyisobutylene/butylene rubber-based adhesives, block copolymer-based adhesives, and the like. These adhesives can be used singly or in combination. Furthermore, it is also possible to add a softening agent, an anti-aging agent, a cross-linking agent, etc. to the pressure-sensitive adhesive, if necessary. Further, the adhesive sheet 30 uses a substrate that uniformly reflects ultraviolet rays, and a region in which an adhesive that does not transmit ultraviolet rays is applied to the substrate is used as a UV absorption portion P, and the substrate has an ultraviolet transparency. It is also possible to configure the UV reflecting portion Q to be the region coated with the adhesive having the .

[Attractant]
As described above, the flying insect trap 100 of the present embodiment uses the edge portion 70 formed in the cover portion 20 and the light and dark pattern of ultraviolet rays formed by the UV absorbing portion P and the UV reflecting portion Q of the adhesive sheet 30. Flying pests can be attracted to the internal space S, but it is effective to use an attractant in combination to bring the flying pests living outside the flying pest trap 100 closer to the flying pest trap 100 . Since the flying insect trap 100 is provided with the drug portion 60 in the cover portion 20, when an attractant for attracting flying insects is stored in the drug portion 60, the attractant diffuses into the internal space S. , and volatilize into the external environment from the inlet 40 . As a result, the edge portion 70 and the UV absorbing portion P and the UV reflecting portion Q of the adhesive sheet 30 can synergistically attract flying pests.

An attractant that can be used in the flying insect trap 100 of the present invention will be described below. As for the dosage form of the attractant, it is preferable to use a gel form so as not to spill or leak from the drug portion 60 . The gel-like attractant is obtained by gelling a liquid substance containing a flying insect-attracting component, which is an active ingredient, with a gelling agent. As the flying insect-attracting component, it is preferable to use a component containing a scent component derived from a flying insect-attracting plant. Examples of flying pest-attracting plants include carnivorous plants of the genus Nepenthes and Saxifrage, insect-pollinated plants of the genus Araceae belonging to the subfamily Araceae, plants of the genus Tulip such as tulips, and plants of the genus Jasmine such as jasmine. mentioned. Among these flying insect-attracting plants, plants of the genus Amaranthus are preferred. Plants belonging to the genus Arum may be classified including plants belonging to the genus Arum. Therefore, in the present specification, plants of the genus Amaranthus and plants of the genus Arum are collectively treated as plants of the genus Amaranthus.

The fragrance components derived from plants belonging to the genus Amaranthus include phenylethyl alcohol, methyl butyrate, α-pinene, and ocimene. Of these, phenylethyl alcohol exhibits an attractant effect on flying pests if the concentration is below a certain level, so it can be suitably used as an attractant for insect repellent products. may exhibit a repellent effect against flying pests. Therefore, when phenylethyl alcohol is used as an attractant, it is possible to control the properties of insect repellent products by appropriately adjusting its concentration.

A fragrant component derived from a plant that attracts flying insects can be used in combination with another attractant. Other attractants that can be used in combination include, for example, balsamic vinegar, apple vinegar, rice vinegar, brown rice vinegar, lees vinegar, soybean vinegar, black vinegar, wine vinegar, sudachi vinegar, red vinegar, persimmon vinegar, malt vinegar, and purple sweet potato. Vinegar, sugar cane vinegar and other vinegars, sugar, brown sugar, honey, liquid sugar, glucose, sucrose, maltose, soft brown sugar, oligosaccharides, polysaccharides, beet sugar, maple syrup, trehalose and other sugars, alcoholic beverages, Examples include sake lees, fruits, processed fruit products, lactic acid products, seafood, processed seafood products, extracts of seafood, meat, processed meat products, extracts of meat, flavors and the like. Among these attractants, balsamic vinegar and soft brown sugar are particularly effective in attracting flying insects. Therefore, when used in combination with a fragrant component derived from a plant that attracts flying insects, they can exhibit a remarkable attracting effect.

Examples of the gelling agent for gelling the liquid containing the flying insect-attracting component include water-soluble polysaccharides and/or water-absorbing resins. Water-soluble polysaccharides include guar gum, xanthan gum, lambda carrageenan, gellan gum, gum arabic, locust bean gum, sodium alginate and the like. Among these, guar gum, xanthan gum, and lambda carrageenan are preferably used because they are excellent in attracting effect and easy to produce. The water absorbent resin includes isobutylene-maleic anhydride copolymer, polyacrylate-based polymer, starch-polyacrylate-based polymer, PVA-polyacrylate-based polymer, PVA-based polymer, carboxymethyl cellulose-based polymer, and the like. mentioned. The above gelling agents can be used alone or in combination. It is preferable to use the gelling agent in a state dissolved in water as a solvent.

In addition to the components described above, other components can be added to the gel-like attractant as appropriate. Other ingredients include, for example, dietary ingredients and base ingredients such as wheat flour, mushrooms, soybean flour, and dry yeast, solvents such as ethanol (e.g., fermented ethanol, synthetic ethanol), bactericides, preservatives, antifungal agents, and stabilizers. Auxiliary components such as agents, surfactants, dispersants, sweeteners, bittering agents, pH adjusters, and colorants. The other ingredients mentioned above can be used alone or in combination.

It is also possible to add an insecticidal component to the gel attractant as long as it does not affect the attraction. Examples of insecticidal components include pyrethroid insecticidal components such as natural pyrethrin, allethrin, flamethrin, prallethrin, resmethrin, phthalthrin, transfluthrin, phenothrin, cyphenothrin, permethrin, and etofenprox; organosilicon insecticidal components such as silafluofen; Neonicotinoid insecticidal ingredients such as imidacloprid, clothianidin and thiamethoxam; organophosphorus insecticidal ingredients such as fenitrothion, diazinon, marathon and prothiophos; oxadiazole insecticidal ingredients such as methoxadiazon; pyrazole insecticidal ingredients such as fipronil; and insect growth regulators such as hydroprene. These insecticidal ingredients can be used alone or in combination.

Thus, the flying pest trap 100 of the present invention is a biomimetics type flying pest trap that imitates carnivorous plants, and is a completely new type of epoch-making insect repellent product that has not existed in the past. .

[Capture test 1: Confirmation of effect by edge part]
Using the flying pest trap having the edge portion of the present invention, a trapping test was carried out for Drosophila, a typical flying pest. A similar test was also conducted on a flying insect trap having no edge portion, and the results were compared with those of the flying insect trap of the present invention.

The flying insect trap used in trapping test 1 had an internal space with a width of about 10 cm, a length of about 16 cm, and a maximum height of about 1 cm. The size of the entrance is 2 to 5 cm ² , and adhesive sheets with various patterns are installed on the main body, and attractants (balsamic vinegar and brown sugar as attractants, xanthan gum as gelling agents, etc.) containing purified water etc. as components).

As a procedure for capture test 1, the flying insect traps of Examples and Comparative Examples were installed on the central floor of a test room of about 25 m ³ , about 100 Drosophila were released, and after 24 hours, the flying insect trap was removed. The number of Drosophila captured by the internal adhesive sheet was counted. This trapping test was repeated three times, and the average number of trapped insects was calculated. The results of capture test 1 are shown in Table 1.

The flying insect traps of Examples 1 to 10, in which the annular edge portion and/or the linear edge portion were formed on the cover portion, had an average number of captured insects of about 40 or more. In particular, with regard to the adhesive sheet, Example 1, in which two colors of hue number 4 (reddish orange) and hue number 7 (reddish yellow) are arranged in a checkered pattern, captured 70 or more Drosophila. and showed excellent trapping performance. On the other hand, in the flying insect traps of Comparative Examples 1 and 2, in which neither the annular edge portion nor the linear edge portion was formed in the cover portion, the average number of trapped insects remained at 20 or less. As described above, it was confirmed that the flying insect trap of the present invention having an edge structure in the cover portion is an excellent insect repellent product compared to the flying insect trap having no edge structure.

[Capture test 2: Confirmation of the effect of fragrant components derived from plants that attract flying insects]
Two colors, Hue No. 4 (reddish orange) and Hue No. 7 (reddish yellow), are arranged in a checkered pattern inside the flying insect trap having the annular edge portion and the linear edge portion used in Example 1. Instead of the attractant used in Example 1, an attractant containing a fragrant component derived from a plant that attracts flying insects, xanthan gum, and other components (purified water, etc.) was used. Capture test 2 was carried out in the same manner as in capture test 1, using what was filled in the part. The results of capture test 2 are shown in Table 2.

As for the fragrance components derived from the flying insect-attracting plant of each example shown in Table 2, phenylethyl alcohol (Example 11), methyl butyrate (Example 12), α-pinene (Example 13), and ocimene (Example 14) are derived from plants of the genus Amaranthus; methyl salicylate (Example 15) and benzaldehyde (Example 15) are derived from plants of the genus Tulip; Example 17) and indole (Example 18) are derived from Jasminum plants.

Each of the flying insect traps of Examples 11 to 18, in which the agent contains the fragrant component derived from the plant that attracts flying insects, has an average number of captured insects of about 40 or more, and uses balsamic vinegar and soft brown sugar as attractants. A trapping effect equal to or greater than that of the flying insect traps of Examples 1 to 10 containing In particular, the flying pest traps of Examples 11 to 14, which used the scent component derived from a plant belonging to the genus Amaranthus, had an average number of trapped insects of 65 or more, demonstrating an extremely remarkable trapping effect.
