TECHNICAL FIELD The present invention relates to a liquid-absorbing member and a bee-controlling container provided with the same.

2. Description of the Related Art Conventionally, various types of feed implements have been proposed for feeding insect pests with liquid feed containing insecticides and the like.

For example, in Patent Document 1, a support lid (3) is fitted to the opening of a container (1) containing an insecticidal liquid, and the upper surface of the support lid (3) is covered with a cloth (4) to form a cloth-covered surface. A pesticide for pests (such as flies) that forms (5) is described. The lower part of the cloth (4) is immersed in the insecticidal liquid, and the insecticidal liquid permeates to the cloth-covered surface (5) by capillary action, so that the cloth-covered surface (5) is wet with the insecticidal liquid. Become. According to Patent Literature 1, pests can be easily exterminated simply by placing an insecticide containing cloth impregnated with an insecticidal liquid in a room or the like.

Japanese Utility Model Laid-Open No. 50-87069

In the insecticide of Patent Document 1, although the cloth-covered surface (5) is wet with the insecticidal liquid at the beginning of use, after a certain period of time has passed after the insecticide is placed, the cloth-covered surface (5) The impregnated insecticidal liquid may evaporate, and the cloth-covered surface (5) (hereinafter also referred to as the cloth surface) may not retain a sufficient amount of the insecticidal liquid for pests to eat. If the insecticidal liquid impregnated on the surface of the cloth evaporates in this way, there is a possibility that the period in which the conventional structure functions effectively as a food implement may be shortened.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a liquid-absorbing member capable of extending the useful life of a food implement and a bee-controlling container provided with the same.

A liquid-absorbing member according to one aspect of the present invention is a liquid-absorbing member impregnated with a liquid food agent for feeding by bees, wherein a concave portion is formed on the upper side of a main body of the liquid-absorbing member, and the concave portion , and has an opening shape for the bees to enter therein.

According to the above aspect, since the concave portion having an opening shape for allowing the bees to enter is formed on the upper side (surface side) of the liquid absorbent member main body, the inside of the concave portion is formed on the upper side (surface side). In comparison, it is less likely to be exposed to wind or the like from the outside, and it is possible to make it difficult to dry the inside of the recess. Therefore, even if the upper side of the liquid-absorbing member main body dries after a certain period of time has passed, the drying of the liquid dietary agent contained in the concave portion is suppressed, so that the bees can continue to eat the liquid dietary agent. . By using such a liquid-absorbing member, bees can eat the liquid food even after the liquid-absorbing member is placed in a predetermined place and a certain period of time has passed. You can extend the period.

In the above aspect, the recess may be formed extending in a direction from the upper side to the lower side of the absorbent member main body.

A bee-controlling container according to an aspect of the present invention includes an absorbent member and a container body that accommodates the absorbent member.

A container body of a bee-controlling container according to an aspect of the present invention includes a lower container for containing a food agent to be eaten by bees, which has an opening at the top, and which is engaged with the opening of the lower container. The inner lid is provided with a bee entrance communicating with the inside of the lower container, and a canopy covering the bee entrance above the bee entrance. be done. The dietary agent to be stored in the lower container is not limited to the liquid-absorbing member shown in the present embodiment, and may be, for example, liquid, gel-like, or water-absorbing polymer-like dietary agents.

Here, in a plan view of the container body viewed from above, it is preferable that a part of the inclined surface extends so as to protrude to the outside of the canopy. 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 is preferably 10 mm or more and 70 mm or less.

The canopy engages with the inner lid or is integrally formed with the inner lid. The canopy can comprise, for example, an arcuate opening for the entry of bees into the interior of the container body. However, as long as it has an opening that communicates between the bee entrance and the outside, it is possible to change the shape, size, etc. of the opening in various ways. The arcuate opening has opposite ends connected to the inner lid and arches connecting the opposite ends. The arch portion has a portion that is formed in a semi-arcuate shape or a curved shape. In addition, it is preferable that the arch portion is provided so that the distance from the inner lid is greatest near the middle of both ends. The distance between the inner lid and the arch portion provided thereabove is preferably 10 mm or more and 35 mm or less. Moreover, it is preferable to provide the inclined surface and the canopy so that the distance between the inclined surface and the canopy provided above the inclined surface is 10 mm or more.

ADVANTAGE OF THE INVENTION According to this invention, the liquid-absorbing member which can extend the effective period as a diet tool, and the container for bee control provided with the same can be provided.

Preferred embodiments of the present invention will be described with reference to the accompanying drawings. The dimensions, shapes, angles, etc. in the drawings may differ from the actual dimensions, shapes, angles, 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, directions such as up, down, left, and right are based on the description in the drawings. As pests targeted by the liquid-absorbing member and the bee-controlling container provided with the same according to the present embodiment, it is particularly preferable to use, for example, wasps, paper wasps, and the like.

The configuration of a bee-controlling container 1 according to this embodiment will be described with reference to FIGS. 1 to 4. FIG. FIG. 1 is a perspective view showing a bee-controlling container 1 according to this embodiment. FIG. 2 is an exploded perspective view of the structure of the bee-controlling container 1 with the absorbent member 40 removed. FIG. 3 is a perspective view showing a state in which the inner lid 20 and the umbrella 30 of the bee-controlling container 1 shown in FIG. 1 are removed. 4A and 4B are views showing the absorbent member 40. FIG.

As shown in FIGS. 1 to 4, the bee-controlling container 1 according to this embodiment includes a lower container 10 (container body), an inner lid 20, an umbrella 30, and a liquid-absorbing member . In the bee-controlling container 1, the liquid food agent 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 inside, and the liquid food agent 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 has an upper opening 105 and an accommodating portion for accommodating the absorbent member 40 therein. The accommodation portion indicates a portion surrounded by the inner wall of the lower container 10 . The inner wall of the lower container 10 refers to the wall surface (bottom surface 101 and side surface 102 shown in FIG. 2) in contact with a space communicating with the opening 105 inside the lower container 10 . 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, when the absorbent member 40 is accommodated in the lower container 10, the protrusion 103 is inserted through a hole 42 formed substantially in the center of the absorbent member 40, and absorbs liquid in the lower container 10. The placement of the sex member 40 is fixed.

In this embodiment, the lower container 10 is formed in a truncated cone shape that increases in diameter toward the top, but is not limited to this shape. The lower container 10 can be changed into various other shapes and sizes as long as it has the function of accommodating the absorbent member 40 inside.

The inner lid 20 is configured to engage with an opening 105 opened upward of the lower container 10 and be fixed to the lower container 10 . The inner lid 20 is formed in a substantially annular shape in plan view. A bee inlet/outlet 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 retaining the bees. The bee retention port 22 is inclined so that the inner side is higher than the outer edge thereof (inclined so that the height increases from the outer edge of the bee retention port 22 toward the center side). Further, the bee retention port 22 is formed so as to protrude radially outward from the outer peripheral surface of the lower container 10 . By providing the bee retention port 22 projecting in this manner, the bees are easily retained, and the bees can enter the lower container 10 through the bee entrance/exit 21 formed in the center of the inner lid 20.例文帳に追加A plurality of engagement holes 23 for engaging the lower end of the umbrella 30 (the lower end of the side wall portion 32) are formed in the peripheral portion of the inner lid 20. As shown in FIG.

In this 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 aspect. The inner lid 20 is provided with one bee inlet/outlet port 21 and four bee retention ports 22 described above, but the number and shape thereof are not limited to those shown in the drawings. That is, if the inner lid 20 has an opening communicating with the lower container 10 and is provided with a port for retaining the bees, the number, shape, etc. thereof can be varied. .

The umbrella 30 is engaged with the inner lid 20 so as to cover the bee entrance 21 above. By engaging the umbrella 30 with the inner lid 20, the liquid-absorbing member 40 exposed to the outside through the bee entrance 21 is covered from above by the umbrella 30, and water, etc. (for example, rain) ) can be suppressed from hitting directly. The umbrella 30 is provided with an arched opening 31 that communicates between the bee entrance 21 and the exterior of the bee-controlling container 1 . The arched opening 31 has a substantially semicircular shape at the portion where the bee retention port 22 is provided. The bees staying in the bee-retaining port 22 can enter the inside of the bee-controlling container 1 (the inside of the umbrella 30 ) through the arched opening 31 and further enter the inside of the lower container 10 through the bee entrance 21 . The side walls 32 positioned on both sides of the arched opening 31 are engaged with the inner lid 20 to fix the umbrella 30 and the inner lid 20 together. Specifically, a guide wall (not shown) extending in a direction from the inner wall toward the bottom surface 101 is provided on the inner wall of the side wall portion 32 of the umbrella 30, and an engagement provided at the lower end of the guide wall is provided. The umbrella 30 and the inner lid 20 are fixed by engaging the portion with the engaging hole 23 formed through the inner lid 20 . The upper surface of the umbrella 30 is provided with a hooking portion 35 for hooking the bee-controlling container 1 to an external member.

In this embodiment, the umbrella 30 is provided with four arched openings 31 and four engagement holes 23, but the configuration is not limited to this. That is, as described above, the umbrella 30 prevents water (for example, rain) from hitting the absorbent member 40 from the outside, and if it has an opening that communicates the bee entrance 21 with the outside, It is possible to change its shape, size, etc. into various things.

The liquid-absorbing member 40 is an impregnated body impregnated with a liquid food agent to be eaten by bees. The impregnated body is a porous material that absorbs the liquid dietary agent by capillary action (for example, when the lower part of the porous material is immersed in the liquid dietary agent, the liquid dietary agent penetrates to the upper part of the porous material due to capillary action). For example, a nonwoven fabric, a sponge, or the like is used.

In the liquid absorbent member 40, a main body portion (liquid absorbent member main body) having a substantially circular plate shape in plan view extends in a direction from the upper surface 40a toward the lower surface 40b (downward in FIG. 4B). A hole 42 (recess) is formed. The holes 42 may be provided in a region of the absorbent member 40 excluding the peripheral edge portion 40c in plan view (FIG. 4A). At least one hole 42 may be provided in the liquid absorbent member 40. For example, as shown in FIG. may be provided in plurality at predetermined intervals in the circumferential direction. The holes 42 are not limited to being formed only in the absorbent member 40 as shown in FIG. It may be formed only on the container 10 . In addition, when the holes 42 are formed only in the lower container 10 , if they are formed along the periphery of the absorbent member 40 , the bees entering the holes 42 impregnate the absorbent member 40 . It is suitable because it is possible to eat the liquid dietary preparation.

The hole 42 has an opening shape for a bee to enter, in other words, an opening large enough for the head of a bee to enter. Specifically, the diameter D (FIG. 4A) of the hole 42 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 be dry, and if the diameter D of the hole 42 is smaller than 5 mm, it is difficult for the bee's head to enter the hole 42. By setting, the head of a bee can enter the inside of the hole 42, and the inside of the hole 42 can be prevented from being exposed to air or the like, so that drying can be suppressed. Bees have a habit of sticking their necks into burrows (for example, hornets and paper wasps stick their heads into burrows in order to receive nutrient liquid from mouth-to-mouth from larvae in the burrows (a thick liquid accumulates on the lower side of the hole 42). In this case, wasps and paper wasps have a habit of sticking their heads into and licking the liquid below the hole 42 ). Therefore, even if the upper surface 40a side of the liquid absorbent member 40 dries, the liquid food agent held inside the holes 42 formed in the liquid absorbent member 40 can be removed by the bees using such behavior of bees. can be eaten, so the effective period as a dietary tool can be extended.

The holes 42 are formed extending in a direction from the upper surface 40a side of the liquid absorbent member 40 toward the lower surface 40b side. In this embodiment, the absorbent member 40 is formed with a hole 42 that communicates between the upper surface 40a and the lower surface 40b. As shown in FIG. 4B, the direction in which the hole 42 extends includes not only the direction (perpendicular direction) from the upper surface 40a side to the lower surface 40b side but also any direction. For example, the holes 42 may extend in different directions for each hole 42 .

In the illustrated example, the absorbent member 40 has a body portion formed in a substantially circular plate shape (substantially columnar shape) having a hole 42 in a plan view, but is not limited to this mode. That is, the absorbent member 40 can be transformed into various forms as long as it has the function of retaining liquid, and may be spherical or rectangular in plan view, for example.

In the present embodiment, the upper side or upper side of the absorbent member 40 means the side of the opening 105 (see FIG. 3 etc.) of the lower container 10 when the absorbent member 40 is installed in the lower container 10. or the exposed surface periphery (the periphery of the upper surface 40a in FIG. 4B).

In addition, in the present embodiment, the hole 42 formed in the liquid absorbent member 40 has a shape penetrating from the upper surface 40a side of the liquid absorbent member 40 to the lower surface 40b side, but it is not limited to this. That is, the hole 42 does not have to penetrate the absorbent member 40 as long as it has an opening large enough to accommodate the head of a bee. can be changed in size. For example, the hole 42 may be a concave portion recessed from the upper surface 40 a side of the liquid absorbent member 40 . The depth from the upper surface 40a of such a concave portion is arbitrary, but if it is at least half the thickness t (FIG. 4(B)) of the liquid absorbent member 40, it is relatively easy to dry compared to the upper surface 40a side. This is preferable because bees can eat the liquid food agent contained in the lower surface 40b side, which is less likely to dry out.

Although the material of the liquid dietary agent impregnated in the liquid absorbent member 40 described above is not particularly limited, for example, an attractant for attracting pests may be blended. As the attractant, those conventionally used can be widely adopted, but for example, dietary components such as carbohydrates (granulated sugar, fructose, maltose, trehalose, etc.), proteins, carbohydrates, lipids: derived from natural products and Prepared aromatic ingredients, pheromones, amino acids, nucleic acids, fats and oils, etc. can be used as active ingredients. These attractants can be used singly or in combination of two or more.

The impregnated amount of the liquid dietary agent is not particularly limited, but for example, the absorbent member can be impregnated with 0.5 to 4 g/cm ³ . From the viewpoint of attracting bees, it is preferable to impregnate the absorbent member with a saturated amount.

The above liquid bait can be used as a liquid poison bait by containing an insecticidal component. Examples of the insecticidal component include pyrethroid insecticides such as allethrin, tetramethrin, resmethrin, phenothrin, flamethrin, permethrin, cyphenothrin, cypermethrin, tralomethrin, empentrin, prallethrin, etofenprox, and silafluofen, phenythion, fenitrothion, temefos, Organophosphorus insecticides such as phoxime, acephate, pyridafenthion, diazinon, malathion, prothiophos, propetamphos, chlorpyrifos, chlorpyrifos-methyl, and DDVP; carbamate insecticides such as NAC, penthiocarb, and propoxur; imidacloburide, methoxadiazon, fipronil, and related compounds , boric acid, hydramethylnon, lithium sulfonate, lithium perfluorooctasulfonate, sulfuramide, 1-methyl-2-nitro-3,3-tetrahydrofurylmethylguanidine and the like. These can be used alone or in combination.

The present invention will now be described with reference to specific examples. The following examples are merely illustrations for helping understanding of the present invention, and the scope of the present invention is not limited thereto.

[Example]
(1) Specimen

As a sample (liquid-absorbent member), a non-woven fabric measuring 5 cm long, 5 cm wide, and 1 cm thick was provided with four through-holes (holes formed by connecting the upper surface and the lower surface of the sample) with a diameter of 1.3 cm. Using. This specimen was impregnated with 40 g of 80% honey water as a liquid dietary agent.
(2) Test insect

Yellowjacket wasp was used as a test insect.
(3) Test method

The specimen of (1) above was placed on a tree in a park where yellowjacket wasps exist, and it was confirmed whether the test insect of (2) above would eat it. After that, the sample of (1) above was placed on concrete for one week without being exposed to rain. After that, the sample was placed on a tree in a park where yellow hornets were present, and it was confirmed whether the test insect in (2) above would eat the sample.
(4) Results

Table 1 shows the test results. ○ in Table 1 indicates that the test insects ate, and X in Table 1 indicates that the test insects did not eat. As a result of observing the eating behavior of the test insect, if a through-hole is formed in the specimen of (1) above, the inside of the specimen (lower part of the specimen) is provided by inserting the head into the through-hole. The test insect was eating. From the results shown in Table 1, it was confirmed that the test insects were eaten regardless of the presence or absence of through-holes in the specimen at the initial stage, but after one week, it was confirmed that the test insects were eaten only when through-holes were formed in the specimen. Therefore, it was verified that the effective period could be extended by forming the through holes. In addition, the test insect rides on the sample, inserts its head into the through-hole, and eats part of the sample. Therefore, when the test insect eats, the liquid food agent adheres to the leg or head surface of the test insect. When such test insects return to the nest, it becomes possible for other bees to eat the liquid food agent adhered to the surface of the test insects. Therefore, when the liquid bait contains an insecticidal component, it is possible to increase the amount of the insecticidal component brought into the nest and enhance the effectiveness of the poisonous bait in the nest.

The embodiments described above are for facilitating understanding of the present invention, and are not intended to limit and interpret the present invention. Each element included in the above-described embodiment and its arrangement, material, conditions, shape, size, etc. are not limited to those illustrated 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. FIG. 5 is a cross-sectional view of the bee control container 1 taken along a plane passing through the center of the two arched openings 31 formed diagonally and the hook 35 .

The inventors of the present application constructed the bee-controlling container 1 so that bees can easily enter the container and human fingers are less likely to touch the liquid food agent. Specifically, the bee-controlling container 1 includes an inner lid 20 and an umbrella 30 (an example of an “umbrella”) provided above the inner lid 20 . Therefore, unless a finger is inserted through the gap between the umbrella 30 and the inner lid 20, the liquid absorbent member 40 accommodated in the lower container 10 is not touched by the finger.

Further, the inner lid 20 is formed with an inclined surface 22</b>A whose height increases toward the bee entrance 21 . As shown in FIG. 2, the inner lid 20 is formed with, for example, a plurality of inclined surfaces 22A. Bees, on the other hand, are sometimes described as having negative geotaxis, ie the propensity of organisms to travel in the direction opposite to gravity. By providing the inclined surface 22A, it becomes possible to promote walking of bees into the container 1 for controlling bees.

Furthermore, by providing the inclined surface 22A, a finger inserted through the gap between the umbrella 30 and the inner lid 20 contacts the inclined surface 22A and is guided obliquely upward. Therefore, it is possible to guide the finger away from the absorbent member 40 that is housed below in the lower container 10 . In addition, even if the user tries to bend the joint of the finger, it becomes difficult for the finger to hit the umbrella 30 and bend, making it difficult for the user to touch the absorbent member 40. - 特許庁

Furthermore, 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 lowering the concentration of the liquid dietary agent impregnated in the absorbent member 40. becomes possible. Even if water or the like adheres to the inclined surface 22A, the inclination of the inclined surface 22A makes it difficult for the water or the like to enter the lower container 10 through the bee inlet/outlet 21 .

Furthermore, by providing the inclined surface 22A, the wind passing through the bee-controlling container 1 is guided upward along the inclined surface 22A. Therefore, it is possible to prevent the air from directly hitting the absorbent member 40 . For this reason, it is possible to suppress fluctuations in the volatilization amount of the liquid dietary agent impregnated in the absorbent member 40 , and thus to suppress fluctuations in the usable period of the absorbent member 40 .

Note that the bee-controlling container 1 may be configured to store a food agent different from the absorbent member 40 . For example, it may be configured to contain a liquid, gel, water-absorbing polymer, or other poisonous bait. Even in such a case, it is possible to provide a container body of a bee-controlling container that allows bees to easily enter and makes it difficult for human fingers to touch the liquid food agent.

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

Moreover, as shown in FIGS. 1 and 5, a portion of the inclined surface 22A may extend to the outside of the umbrella 30 (an example of a "canopy body"). By configuring in this way, it is possible to make bees flying around the bee-controlling container 1 recognize the inclined surface 22A. Therefore, it is possible to encourage 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 that extends to the outside of the umbrella 30 (the portion that protrudes outward from the umbrella 30 in plan view) is 2 mm or more. is preferred. More preferably, it is 7 mm or more. If the distance D6 is shorter than 2 mm, it becomes difficult for the bee to put its legs on the bee, so that it becomes difficult for the bee to land on the inclined surface 22A. At least part of the inclined surface 22A may be provided on the surface of the bee retention port 22. FIG. 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 retention 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 to the bee entrance 21 in the radial direction is preferably 10 mm or more and 70 mm or less, more preferably 20 mm or more and 60 mm. It is below. If the distance D4 of the inclined surface 22A is less than 10 mm, it becomes difficult for the bee to land on the inclined surface 22A. Moreover, when the distance D4 of the inclined surface 22A is smaller than 10 mm, the human finger tends to touch the food material. Therefore, it is preferable that the length of the inclined surface 22A is 10 mm or more. If the distance D4 of the inclined surface 22A is larger than 70 mm, the bee-controlling container 1 becomes large, and the place where the bee-controlling container 1 is installed is limited. In addition, since the average length of the second finger of a person is about 70 mm, there is little possibility that the fingertip will touch the absorbent member 40 even if the distance D4 is not 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 the possibility of the bees reaching the bee entrance 21 is reduced. For example, in this embodiment, the distance D4 is 25 mm.

Umbrella 30 may comprise, for example, an arcuate opening 31 for entry of bees. However, if it has an opening that communicates between the bee entrance 21 and the outside, it is possible to change the shape and size of the opening into various shapes. The arched opening 31 has both ends connected to the inner lid 20 and an arch connecting the ends. The arch portion has a portion that is formed in a semi-arcuate shape or a curved shape. Also, the arch portion is provided so that the distance from the inner lid 20 is greatest near the middle of both ends.

As shown in FIG. 1 and the like, the umbrella 30 has four arched openings 31 that are rotationally symmetrical by 90 degrees with respect to a central axis that vertically penetrates the center of the bee-controlling container 1 . Therefore, it is possible to allow bees to enter the bee-control container 1 from all directions. Furthermore, by providing at least two arched openings 31 in diagonal directions, 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-controlling container 1 promotes the spread of the volatilized attractant around the bee-controlling container 1. it becomes possible to Here, the height of the arched opening 31 with respect to the inclined surface 22A of the inner lid 20 (vertical distance between the inclined surface 22A and the intermediate portion of the arched opening 31) is 10 mm or more and 35 mm or less. 10 mm or more and 30 mm or less is more preferable. When the height of the arch-shaped opening 31 from the inner lid 20 is 10 mm or more, even a large-sized bee such as a hornet can enter the bee-controlling container 1 . On the other hand, if the height of the inner lid 20 and the arched opening is greater than 35 mm, human fingers are more likely to touch the food. In addition, large insects other than bees invade. In this 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 arched opening 31 with respect to the inclined surface 22A of the inner lid 20 becomes smaller as the bee entrance 21 is approached. As shown in FIG. 5, the ceiling surface 30A and its vertical direction at the end of the arched opening 31 on the side of the bee entrance 21 where the height of the arched opening 31 with respect to the inclined surface 22A as a reference is the smallest. By setting the height D1 with respect to 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, it becomes possible for bees to easily enter the bee-controlling 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, more preferably 15 mm or more and 80 mm or less.

Moreover, it is preferable to maintain a distance of 10 mm or more between the inclined surface 22A and the umbrella 30 provided thereabove. By adopting such a structure, it becomes easy for bees to walk on the inclined surface 22A and enter the bee-controlling 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 of the umbrella 30 (inner surface facing downward) 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 bee entrance, may have a horizontal ceiling surface 30A (FIG. 5) in the vertical section (FIG. 5). When such a ceiling surface 30A is provided, on the other hand, the inclined surface 22A is formed so that the height increases toward the bee entrance 21, so the interval between the inclined surface 22A and the umbrella 30 approaches the bee entrance 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 can be restricted, and the finger can be easily guided upward along the inclined surface 22A. Note that even with a structure other than the arch-shaped opening 31, a ceiling surface that is horizontal in a vertical cross section may be provided in a portion of the umbrella 30 that serves as an entrance for bees.

Also, the diameter D3 of the bee entrance 21 is preferably 10 mm or more and 140 mm or less, 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, it is preferable that the diameter D3 of the bee entrance 21 is at least 10 mm or more. On the other hand, if the diameter D3 is larger than 140 mm, the bee-controlling container 1 becomes large, which limits the installation location of the bee-controlling container 1 . Therefore, the diameter D3 of the bee entrance 21 is preferably 140 mm or less. For example, in this embodiment, the diameter D3 is 60 mm.

A line segment L1 shown in FIG. 5 indicates the position of the upper end of the absorbent member 40 . A distance D5 (height difference in the vertical direction) between the upper end of the absorbent member 40 and the inner diameter side end of the inclined surface 22A is preferably 1 mm or more and 45 mm or less, more preferably 10 mm or more and 40 mm or less. If the interval D5 is smaller than 1 mm, the liquid-absorbent member 40 is likely to come into contact with the wind passing through the bee-controlling container 1, and thus the drying of the liquid-absorbent member 40 is accelerated. In addition, when the finger joint is bent, the fingertip easily touches the absorbent member 40 . By setting the distance D5 to 1 mm or more, it is possible to suppress drying of the absorbent member 40 and realize a structure in which it is difficult for a person's fingertips to touch the absorbent member 40 . On the other hand, when the interval D5 is larger than 45 mm, it becomes difficult for the bees to escape. For example, in this embodiment, the distance D5 is 15 mm.

In addition, 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 21, the end point of the inclined surface 22A, that is, the inner diameter side end of the inclined surface 22A and the absorbent member The sum of the distance D5 with 40 is preferably 20 mm or more, more preferably 30 mm or more. If the sum of the distance D4 and the interval D5 is smaller than 20 mm, the fingertips are likely to touch the liquid absorbent member 40 . For example, in this embodiment, the sum of the distance D4 and the interval D5 is 40 mm.

Further, as shown in FIG. 2, grooves G extending in the radial direction may be provided between adjacent inclined surfaces 22A. By configuring in this way, it becomes possible for the bee to hook its legs, so that it becomes possible to assist the bee to climb the slope 22A. In addition, you may provide a convex part or unevenness|corrugation in 22 A of inclined surfaces.

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