DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bumble bee hive.

[0002]

2. Description of the Related Art There is a honeybee as a pollinating insect, and this honeybee has been used for pollination of apples, strawberries and the like. However, since honey bees do not visit tomatoes and eggplants that do not have nectar, they cannot be used for pollination of tomatoes and eggplants. In contrast, exotic bees, for example, European Bumble Bee distributed in Europe, have a queen and have the habit of collecting nectar and pollen. Are also being imported and used from Europe.

However, if an exotic bee escapes into Japan and escapes naturally, it will affect the native ecosystem. As means for solving the problem, an invention disclosed in Japanese Patent Application Laid-Open No. 6-343368 has been proposed. According to this, a cover is provided at the entrance and exit of a nest box where colonies of exotic pollinating insects live, and this cover has an opening (about 5 mm) large enough to allow worker bees to pass freely, but not for queen bees to pass. It is provided.

[0004]

However, when the number of bees in the hive increases, the number of entrances and exits may be one or two, as described in the above-mentioned publication. It was relatively narrow due to the opening, and even though it was a worker bee with a chest height of about 4.5 mm, it was difficult to pass, and a series of bees caused traffic jam at the entrance. Therefore, it is natural to think that the number of entrances and exits should be increased.However, many entrances and exits need to be provided with doors that prohibit entry and exit of bees and caps that can move in only one direction to collect bees. There was a problem in that the workability was degraded by the provision.

[0005] Therefore, an object of the present invention is to solve the traffic jam of bees entering and exiting at the entrance on the outer wall surface of the hive.

[0006]

Therefore, in the bumblebee nest box according to the present invention, the front chamber is formed by one or more wall surfaces constituting a part of the nest body inside the wall surface where the entrance is formed. One or a plurality of long holes are formed in one or more wall surfaces separating the anterior chamber and the nest body in a lateral direction (claim 1). The height of the slot is such that the queen of bumblebees cannot pass. This allows worker bees to pass freely at the entrance and exit, and when they enter the nest, they can enter and exit the nest body through one or more long holes formed on one or more wall surfaces that constitute a part of the nest body It is. In the long hole, many worker bees can enter and leave side by side, so there is no congestion of bees. Naturally, the queen cannot escape from the slot, preventing natural growth.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 3 show a bumblebee nest box 1 made of synthetic resin, cardboard or the like.
2b, 2c, 2d, 2e, and 2f are formed in a rectangular parallelepiped, for example, 27 cm in length, 24 cm in width, and 27 in length.
cm. In the nest body 4 in the nest box 1, child birth of a bumblebee is performed, and 30
It is equipped with a hole for giving about% sucrose and a pollen holder.

In this bumble bee hive 1, two circular entrances 3, 3 are formed on the wall surface 2 a on the front side, and bumble bees enter and exit the entrances 3, 3. Since the entrances 3 and 3 have a relatively large diameter and can be entered and exited even by the queen bee, the bees can fly in and out, and no traffic jam occurs even if the bees increase.

Then, a wall 5 for partitioning from the nest body 4 is provided inside the front wall 2a of the nest box 1, and a front chamber 7 is provided between the wall 5 and the front wall 2a. As shown in FIGS. 2 and 3, a long hole 6 is formed in the wall surface 5 in a lateral direction at a lower portion. This long hole 6 has a height of 5 mm to 7 mm.
The queen bee cannot pass through, and a plurality of them are formed, and three are formed in this embodiment. The lateral dimension of the slot 6 is at least 10c
m, so that even a large number of bees can be easily accessed.

FIG. 4 shows a second embodiment of the present invention. In this example, four wall surfaces 5a,
The nest body 4 composed of 5b, 5c, 5d is housed therein, and the wall surfaces 5a, 5b, 5c,
An anterior chamber 7 'is formed around the periphery between 5d and the wall surfaces 2a, 2b, 2c, 2d of the nest box 1. Wall surface 5a,
Below 5b, 5c, 5d, there are long holes 6, 6, respectively.
6, 6 are formed. This elongated hole has the same height as that of the above-described embodiment, so that the queen bee cannot enter or exit.

In this embodiment, the entrances 3, 3
Has a size similar to that of the above-described embodiment, and has a configuration in which a bee can easily enter and exit the front room 7 '. Therefore, when the bees easily pass through the entrances and exits 3, 3 and enter the front chamber 7 ', they can enter the nest body 4 from the elongated holes 6, 6, 6, 6 formed below. The length of the long hole 6 in the lateral direction is long, and the working bees do not continue.

FIGS. 5 and 6 show a third embodiment of the present invention. In this example, wall surfaces 5e, 5f, 5g, 5h, and 5i which are one wall surface of a nest body 4 inside a nest box 1 are shown.
And the front wall 2a of the birdhouse 1 provide a front room 7 ''. These wall surfaces 5e to 5i are unitized with five surfaces,
It is attached to the front wall surface 2a. These walls 5e to 5
In i, a large number of horizontally long slots 6 are formed.

The elongated hole 6 has a height of about 5 mm to 7 mm similarly to the above-described embodiment, so that the queen bee cannot pass through, and has a short lateral dimension of 15 mm and a long dimension. Is 40 mm. The entrance 3 is provided in the front room 7 constituted by the wall surfaces 5e to 5i.
Is open. Therefore, the worker bee can move freely from the nest body 4 to the anterior chamber 7 ″ through the elongate hole 6 on the wall surface and exit from the entrance 3 to the outside. They cannot pass and cannot escape. The worker bee has a slot 6
Can be entered and exited side by side, so there is no congestion of bees. In the other hole 3, a one-way collection unit 9 is provided, the diameter of the tip is set to 5 mm or less,
Not only the queen bee but also the worker bee cannot enter from the nest side.

The bumblebee used in the present embodiment is a bumblebee, which is used for suppressing the growth in Japan. Of course, the bumblebee distributed in Japan may be used. A young queen bee, born after the nest's heyday, can be used for collection.

[0016]

As described above, conventionally, the queen bee is provided with an opening for preventing spontaneous growth by going outside and juxtaposed to the entrance and exit. According to the report, a long hole was provided in a wall constituting a part of the nest body at a position distant from the entrance, so that it became wider in the lateral direction, and traffic jams did not occur even if worker bees multiplied.
