However, the present inventors may behave as if a bee attracted by a bee attractant stored in a bee trap having a conventional structure and flies in search of a landing place, and the flew bee may behave. It was discovered that they may give up landing and fly away, which affects the capture of bees.

Therefore, an object of the present invention is to provide a bee catcher having a structure that makes it easy for bees to land so that bees can be caught well.

The present inventors have conducted diligent studies in order to solve the above problems, and have invented a bee trap having the following structure.

Specifically, in one embodiment of the present invention, a container for accommodating a drug for attracting or killing bees in the internal space, and a lid portion in which a catch port communicating with the internal space of the container is formed. Provides a bee catcher with a port for the bee to land on.

The term "capturing a bee" in the present invention includes, in a broad sense, the case where a bee is temporarily captured inside a container. For example, it includes a case where a bee is temporarily caught inside a container and a poison bait is fed to the bee to return to the home.

The port portion is preferably extended in a direction away from the capture port. The capture port may be provided so as to open upward (including the case where it faces diagonally upward) or laterally. The port portion may be provided with an inclined portion that inclines downward as the distance from the capture port increases. When the port portion is provided with the inclined portion, it is possible to encourage the bee landing on the inclined portion to walk toward the capture port.

The port portion and the lid portion may be provided integrally. The port portion and the lid portion may be provided as separate bodies. By providing both integrally, it becomes possible to continuously form the surface of the lid portion and the surface of the port portion. Therefore, the bee landing on the port portion can easily walk toward the capture port.

The terms used in the present specification to indicate directions such as upward, downward, lateral, and away directions indicate directions when a bee catcher is used.

The container contains a bee attractant or bee pesticide. Before use, a bee attractant or a bee insecticide may be contained in a bag or the like separate from the container.

Further, a plurality of capture ports and port portions may be provided respectively. The lid may be formed with a second capture port that communicates with the internal space of the container. The bee catcher may further include a second port portion for the bees to land. The capture port and the second capture port may be provided at the center of rotation with respect to the axis passing through the center of the lid portion in the top view. The port portion and the second port portion may be provided at the center of rotation with respect to the axis passing through the center of the lid portion in the top view.

Further, when a plurality of capture ports and port portions are provided, the straight line connecting the tips of the two port portions may be configured to cross the two capture ports in a top view. As used herein, the "tip of the port portion" is defined as the point farthest from the opening edge of the port portion in the top view. When there are a plurality of points farthest from the opening edge, the tip of the port portion is defined as the point closest to the capture port among such points.

When the port portion has an inclined portion, unevenness may be formed on the inclined surface of the surface thereof. For example, grain may be formed. By forming the grain, it becomes possible to provide unevenness that is easily caught on the limbs of the bee. Further, instead of the grain, one or a plurality of convex portions protruding from the surface of the port portion may be provided.

The bee catcher may also be provided with a roof body that is provided above the catch opening with a space. By providing the roof body, it is possible to prevent rain or the like from entering the inside of the container through the capture port and changing the concentration or other characteristics of the bee attractant or the like. The lid portion may be partially in contact with the roof body or integrally formed with the roof body in order to support the roof body.

Further, in the top view, the port portion may include a portion protruding from the roof body. With such a configuration, the bee flying from above can easily visually recognize the port portion.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The following embodiments are examples for explaining the present invention, and the present invention is not intended to be limited only to the embodiments.
[First Embodiment]

FIG. 1 is a perspective view of the bee catcher 10 according to the first embodiment. FIG. 2 is a front view of the bee catcher 10, FIG. 3 is a side view of the bee catcher 10, and FIGS. 4 and 5 are plan views (top views) of the bee catcher 10. However, the bee catcher 10 in FIGS. 3 and 5 has the roof body 16 removed.

As shown in these drawings, the bee catcher 10 includes a container 12, a lid 14, and a roof 16.

As shown in FIG. 2, the container 12 is a tubular container having an inverted tapered side surface whose diameter increases as the distance from the bottom surface increases. A circular opening is formed in the upper part of the container 12. For example, the height from the bottom surface to the upper end of the container 12 is 50 mm to 150 mm. Further, the outer peripheral surface of the container 12 is formed to be smooth.

In the internal space of the container 12, for example, a bee attractant (an example of "drug") for attracting a wasp or a paper wasp, which is a bee of the Hymenoptera hornet family, can be accommodated. As the bee attractant, a liquid attractant containing a component known to have an effect of attracting bees, such as a fruit juice component or a sap component, can be used. The bee attractant may be mixed with an insecticidal component for killing bees.

The lid body 14 includes a lid portion 14L and two first port portions 14P1 and a second port portion 14P2 connected to the lid portion 14L. In the present embodiment, the lid portion 14L, the first port portion 14P1 and the second port portion 14P2 are integrally formed by resin molding. However, they may be composed of separate parts that can be separated from each other.

The lid portion 14L is a portion of the lid body 14 that has a function of engaging with the container 12 and covering the opening of the container 12. Further, the lid portion 14L is formed with two capture ports H1 and a capture port H2 for allowing bees to enter the container 12.

Specifically, the lid portion 14L includes an engaging portion 14A (FIG. 1) that engages with the container 12, a first flat portion 14B1 on which the capture port H1 is formed, and a capture port H2, as shown in FIG. The second flat portion 14B2, the first wall portion 14C1 erected from the first flat portion 14B1, the second wall portion 14C2 erected from the second flat portion 14B2, and the inclination of the first wall portion 14C1. An inclined surface portion 14D for connecting the upper side to be formed and the inclined upper side of the second wall portion 14C2 is provided.

The engaging portion 14A is a portion that engages with the opening edge forming the opening of the container 12. Various means can be used as a means for engaging the lid portion 14L and the container 12. For example, when a notch is formed in one of them, a notch with which the notch engages is provided, and the lid portion 14L is rotated relative to the container 12, the notch engages with the notch and the lid portion. 14L may be mounted on the container 12 to suppress rotation in the opposite direction. Further, a female screw may be formed on the lid portion 14L, and a male screw to be screwed onto the female screw may be formed on the upper edge portion of the container 12. Further, with the bee attractant stored in the internal space of the container 12, the two may be adhered with an adhesive or the like.

The first flat portion 14B1 includes a flat surface facing upward. Further, a capture port H1 that opens upward is formed in the first flat portion 14B1. As shown in FIG. 5, the first flat portion 14B1 is formed in a fan shape in a top view, and extends radially outward from the opening center side of the container 12 to reach the opening edge of the container 12. Has sides. Further, the capture port H1 is formed at a position close to the center of the opening, away from the opening edge in the top view. The diameter of the capture port H1 is formed to be, for example, 15 to 25 mm in consideration of the size of the bee to be captured. The first flat portion 14B1 may be provided so as not to reach the opening edge of the container 12. For example, an inclined surface may be provided between the first flat portion 14B1 and the opening edge of the container 12, and the inclined surface may connect the first flat portion 14B1 and the container 12.

The first wall portion 14C1 is formed upright from the first flat portion 14B1. The connecting portion between the first wall portion 14C1 and the first flat portion 1B1 connects two separated points on the opening edge in a top view and has a curve that is convex toward the center of the opening. Therefore, the first wall portion 14C1 has a curved curved surface that faces in the horizontal direction and is recessed in the opening center direction. As shown in FIG. 3, the first wall portion 14C1 has the maximum height in the vicinity of the capture port H1, the height decreases as the distance from the capture port approaches the opening edge, and the height increases on the opening edge. It has two upper sides that slope to be near zero.

The first port portion 14P1 is connected to the first flat portion 14B1 on the opening edge, and is formed so as to project in the outer diameter direction so as to be separated from the opening. As shown in FIG. 2, the first port portion 14P1 includes an inclined portion that inclines downward as the distance from the opening increases. Further, as shown in FIG. 3, the amount of protrusion from the capture port and the opening edge is maximized in the central portion, and the amount of protrusion from the opening edge decreases as the distance from the central portion and the approach to the end portion increase.

However, various shapes can be applied as the first port portion 14P1. For example, the first port portion 14P1 may be provided so that the distance from the opening edge is constant.

In top view, the maximum amount of protrusion of the first port portion 14P1 from the opening edge is preferably, for example, half or more of the diameter of the capture port. With this configuration, the bee to be captured can at least hook its forelimbs on the first port portion. In the present embodiment, the diameter of the capture port is 15 to 25 mm, and the maximum amount of protrusion from the opening edge of the first port portion in the top view is 10 to 20 mm.

Further, the surface of the inclined portion of the first port portion 14P1 may be textured by embossing. If the bees are textured, the bees to be captured can easily hook their forelimbs and the like. In addition, instead of the grain, or together with the grain, a convex portion protruding from the surface may be provided on the surface of the inclined portion of the first port portion 14P1. The convex portion may be formed on a concentric circle centered on the center of the opening of the container 12 in a top view. Further, a plurality of convex portions may be provided. For example, in top view, convex portions may be formed on two concentric circles centered on the center of the opening of the container 12. Further, in the top view, the opening edge, the first convex portion formed on the opening edge side, and the two convex portions formed on the outer diameter side apart from the convex portion may be formed at equal intervals.

As shown in FIG. 5, the second flat portion 14B2, the capture port H2, the second wall portion 14C2, and the second port portion 14P2 are the first flat portion 14B1, the capture port H1, the first wall portion 14C1, and the first port. The portion 14P1 is formed 180 degrees rotationally symmetric with respect to the center of the opening in the top view. Therefore, detailed description thereof will be omitted. Further, in top view, a straight line connecting the tip farthest from the opening edge of the first port portion 14P1 and the tip farthest from the opening edge of the second port portion 14P2 (a straight line passing through the center of the opening and traveling in the left-right direction of the paper surface). ) Pass through the capture port H1 and the capture port H2.

In top view, a hanging portion 14E projecting upward is formed on the axis passing through the center of the opening (FIG. 1). A hole for suspending the bee catcher 10 is formed in the suspension portion 14E.

Further, the inclined surface portion 14D (FIGS. 3 and 5) is provided so as to connect the inclined upper side of the first wall portion 14C1 and the inclined upper side of the second wall portion 14C2. The inclined surface portion 14D has a substantially conical inclined surface.

Further, the bee catcher 10 includes a roof body 16. The roof body 16 is provided so as to cover above the capture port H1 and the capture port H2. In the present embodiment, as shown in the top view of FIG. 4, the entire lid portion 14L including the capture port H1 and the capture port H2 is covered with the roof body 16. On the other hand, the tips of the first port portion 14P1 and the second port portion 14P2 project from the roof body 16. An engaging hole for engaging with the hanging portion 14E is formed in the central portion of the roof body 16.

An example of how to use the bee trap 10 as described above will be described below.

The user opens the bee attractant contained in another bag or the like, puts it in the container 12, and dilutes it with water to put a liquid bee attractant having an appropriate concentration for attracting the bee into the container 12. Can be housed inside.

The user then engages the lid 14 with the container 12 and then engages the roof 16 with the lid 14. Various means can be used as means for engaging the lid body 14 and the container 12. For example, a convex portion is formed on one of them, and a notch with which the convex portion engages is provided on the other side so that the lid body 14 is rotated relative to the container 12 or the lid body 14 approaches the container 12. When relatively moved, the convex portion may engage with the notch, the lid 14 may be attached to the container 12, and the container 12 may be prevented from moving relative to the lid 14. Further, a female screw may be formed on the lid body 14, and a male screw to be screwed onto the female screw may be formed on the upper edge of the container 12. Further, with the bee attractant stored in the internal space of the container 12, the two may be adhered with an adhesive or the like. When the lid 14 and the container 12 are engaged by rotating, the opening of the container 12 is preferably circular. When the lid 14 and the container 12 are engaged without rotating, the opening of the container 12 is not limited to a circle, and may be a polygon such as a rectangle or a hexagon. Further, one of the container 12 (or the container 14) is provided with an engaging claw that protrudes in the direction of the lid 14 (or the container 12), and the lid 14 (or the container 12) is fitted with the engaging claw. It may be engaged by providing an engaging hole and fitting the two. Next, the user installs the bee catcher 10 by suspending the bee catcher 10 through a string or the like through a hole of the hanging portion 14E in a place where bees are likely to fly.

After that, the bee attractant in the container 12 volatilizes and is discharged to the outside of the container 12 from the capture port H1 and the capture port H2. Since the roof body 16 is provided above the capture port H1 and the capture port H2, a part of the volatilized bee attractant stays in the space between the roof body 16 and the lid body 14. Further, the gap between the inclined surface portion 14D and the roof body 16 (the distance in the height direction between the inclined surface of the inclined surface portion 14D facing the roof body 16 and the inner surface of the roof body 16 facing the inclined surface portion 14D) is a capture port. From the gap between H1 or the capture port H2 and the roof body 16 (the distance between the capture port H1 (or the capture port H2) and the inner surface of the roof body 16 facing the capture port H1 (or the capture port H2) in the height direction). small. Therefore, the airflow flowing along the inclined surface in the narrow space between the inclined surface portion 14D and the roof body 16 flows into the space surrounded by the first flat portion 14B1 and the roof body 16, or the second flat portion 14B2 and the roof body. It is presumed that it promotes the flow into the space surrounded by 16. Therefore, it is presumed that the attractant originally staying in this space can be discharged toward the first port portion 14P1 and the like.

The bees flying around the bee trap 10 are attracted by the bee attractant discharged from the gap between the first flat portion 14B1 or the second flat portion 14B2 and the roof body 16, and the first flat portion 14B1 or the first flat portion 14B1 or the first flat portion 14B1 or the roof body 16. 2 Approaches the flat portion 14B2. At this time, since the tips of the first port portion 14P1 and the second port portion 14P2 protrude from the roof body 16, the bee can easily see the first port portion 14P1 or the second port portion 14P2. Further, the first port portion 14P1 is connected to the first flat portion 14B1, and the second port portion 14P2 is connected to the second flat portion 14B2. Therefore, the bee is more likely to land on the lid 14 as compared with the case where the first port portion 14P1 or the like is not provided. Therefore, it is possible to suppress the case where the bee flies away without landing.

For example, a bee that has landed on the first port portion 14P1 walks toward the capture port H1. At this time, the first port portion 14P1 is provided with an inclined portion that inclines downward as the distance from the capture port H1 increases. Therefore, in the case of a bee having a negative running habit as a habit, it is possible to promote the bee to walk toward the capture port H1. After that, the bee invades the container 12 from the capture port H1. The container 12 is filled with a liquid bee attractant. Further, water droplets or the like are attached to the inner wall of the container 12. For this reason, the bee cannot climb the inner wall of the container 12 and go out, and eventually drowns.

As described above, according to the bee catcher 10 according to the present embodiment, since the first port portion 14P1 or the second port portion 14P2 is provided, it is compared with the bee catcher not provided with these port portions. , It becomes possible to make it easier for the bee to land on the lid 14.

The position, shape, and number of port portions can be changed as appropriate within the normal exertion of creative ability. For example, the port portion may extend horizontally. Further, the number of port portions may be one or three. Further, the port portion may be formed over the entire circumference. When the bee to be captured is a giant hornet having a body length of about 30 to 45 mm, the size in the direction away from the opening edge of the port portion is preferably about 3 to 50 mm. Further, the amount of protrusion of the port portion from the opening edge in top view is preferably about 3 to 50 mm. Further, when the roof body 16 is installed, the amount of protrusion from the roof body 16 in the top view is preferably 3 to 50 mm. Further, the number of capture ports may be one or more. However, by providing the two capture ports symmetrically, even a bee flying from the opposite direction can be easily captured. Further, the roof body 16 is provided to narrow the distance between the inclined surface portion 14D and the roof body 16, while increasing the distance between the capture port H1 and the like and the first flat portion 14B1 and the like and the roof body 16. Therefore, it is presumed that an air flow traveling along the inclined surface of the inclined surface portion 14D in the gap between the inclined surface portion 14D and the roof body 16 is likely to occur. It is presumed that by putting it on this air flow, it becomes easier to discharge the drug that has volatilized and discharged from the capture port H1 or the capture port H2 in the outward direction from the first flat portion 14B1 or the second flat portion 14B2. NS.

In addition, the inventors of the present application have noted that bees may behave in search of the entrance after landing. The bee catcher 10 according to the present embodiment includes a first port portion 14P1 or a second port portion 14P2 that is directly connected to the first flat portion 14B1 or the second flat portion 14B2. Therefore, the bee landing on the first port portion 14P1 or the like can easily proceed toward the first flat portion 14B1 (or the second flat portion 14B2) in which the capture port H1 (or the capture port H2) is formed. It will be possible. In particular, when the first flat portion 14B1 and the first port portion 14P1 are integrally formed and there is a portion connected by a curved surface or a flat surface which is smoothly connected, the bee can easily walk. ..

The roof body 16 can prevent rainwater or the like from entering the container 12 from the capture port H1 and the capture port H2 and reduce the concentration of a drug such as a bee attractant. However, when the bee catcher 10 is installed indoors or the like, the roof body 16 does not necessarily have to be installed.

When the roof body 16 is provided, the roof body 16 may be formed integrally with the lid body 14. Further, the roof body 16 may be formed in a disk shape, for example, because it is sufficient to prevent rainwater or the like from entering the inside of the container 12 from the capture port H1 or the like.

As a comparative example of the bee catcher 10, the inventors of the present application use a comparative bee catcher having the same structure as the bee catcher 10 except that the port portion 14P1 and the port portion 14P2 are not provided. An experiment was conducted to compare the number of captured animals.

Put the same bee attractant in the bee catcher 10 and the comparison bee catcher, place multiple bee catchers 10 and the comparison bee catcher at intervals of several meters, and count the number of bees caught after 2 weeks. did. As a result, the bee catcher 10 was able to catch more bees. Therefore, the bee catcher 10 is provided with the port portion 14P1 and the port portion 14P2, so that the bees can be landed and captured more easily.

Further, the present invention can be modified in various ways as long as it does not deviate from the gist thereof. For example, some components in one embodiment may be added to other embodiments within the normal creative abilities of those skilled in the art. Also, some components in one embodiment can be replaced with corresponding components in another embodiment.
