Description

  The present invention relates to a breeding container capable of suitably breeding insects, particularly beetles and stag beetles.

In recent years, there are many enthusiasts who grow beetles from the larva stage, especially stag beetles, and the stag beetles are attractive for their size and male figure, and have reached market value beyond the scope of hobbies. . The applicant of the present application has previously filed a beetle breeding container capable of suitably breeding beetles (see Patent Document 1). This breeding container is used to fill the breeding floor and raise larvae to allow adults to be raised. At least the bottom surface of the inner surface is formed into a rough surface, thereby eliminating the emergence failure when hatching on the bottom surface. This is what we planned.
Japanese Patent No. 3281356

  By the way, when raising insects in a breeding container, after filling the bottomed cylindrical breeding container with meal such as sawdust or rice bran, inoculate and culture the mushroom species. Then, the breeding floor is made, one larva is put in the breeding container, and the breeding is started, and it is transferred to a new breeding container as the larva grows. Larvae grow into end-stage larvae, then hatch and eventually emerge as adults, but before they grow, they need to be transferred to new breeding containers 3-4 times for food exchange.

  However, when changing to a new breeding container and exchanging the food, take out all the breeding floors containing uneaten food in the breeding container and the growing larvae from the container, and destroy the removed breeding floor. In general, the larvae are picked and removed by hand, and the larvae are put in a breeding container filled with a breeding floor filled with new food. As a result, the larvae that were transferred to the new breeding container destroyed the habitat where they lived and were accustomed to the larvae, resulting in considerable stress, resulting in the growth stopping or the expected size. Failure to grow is likely to occur, and in the worst case, larvae may die. In addition, when the larvae are once taken out from the breeding container, or when the removed larvae are picked up by hand and put into a new breeding container, there is a possibility that insects such as fungi and mites adhere to the larvae. Moreover, the transfer to a new breeding container involves a troublesome work of taking out all of the breeding floor and the growing larvae from the container, so that the work efficiency is poor. In particular, when a large number of larvae are reared up to adults as business, it takes a lot of labor to transfer to a new breeding container for exchanging food.

  The present invention has been made in view of the above-described conventional problems, and does not give any stress to the larvae, and does not cause the larvae to be infested with pests such as bacilli and mites. It aims at providing the insect breeding container which can perform.

  In order to achieve the above object, an insect breeding container according to claim 1 is a cylindrical container body, and an upper part that is detachably attached to the upper end portion of the container body and covers the upper end opening of the container body. A connecting cylinder in which a connecting part that can be connected to the lower end part and the upper end part of the container body in communication with each other is formed at the upper and lower portions of the inner peripheral surface; and the upper and lower parts on the inner peripheral surface of the connecting cylindrical body A lower lid that covers the lower end opening of the container body when the connection cylinder is connected to the container body, the lower end of the container body. The upper end opening of the container body is filled with a breeding floor and the larvae are placed inside the container body that is covered with a lower end opening by connecting the upper connecting portion of the connecting cylinder. It is configured to be covered with the upper lid. .

  The invention according to claim 2 is the invention according to claim 1, wherein the lower end cover body is a thin wall set at a strength to break by pressurization on the inner peripheral surface between the upper and lower connecting portions inside the connecting cylinder. It is integrally formed with an annular easily breakable portion interposed.

  According to a third aspect of the present invention, in the first aspect of the invention, the lower end lid is detachably attached to the inner peripheral surface between the upper and lower connecting portions inside the connecting cylinder by means of fitting means. .

  The invention according to claim 4 is the invention according to any one of claims 1 to 3, wherein the container main body, the upper lid body, and the connecting cylinder body are either screwed or press-fitted into each other. The connection means is detachably connected.

  The invention according to claim 5 is the invention according to any one of claims 1 to 4, wherein the container body is mounted on the inner peripheral surface of the side wall of the upper lid and the inner peripheral surfaces of the upper and lower sides of the connecting cylinder. In the state, a slit-like ventilation groove that communicates the inside of the container main body with the outside air is formed.

  According to a sixth aspect of the present invention, there is provided a cylindrical container body, an upper lid body that is detachably attached to the upper end portion of the container body and covers the upper end opening of the container body, a lower end portion of the container body, A connecting cylindrical body in which connecting portions that can be connected to the upper end portion are respectively connected to the upper and lower portions of the inner peripheral surface, and a lower end portion of the container main body are detachably mounted to cover the lower end opening of the container main body. A lower lid body, and a container floor filled with a lower end opening when the lower lid body is attached is filled with a breeding floor, and larvae are placed therein, so that the upper end opening of the container body is placed on the upper portion. The larva is brought into a breeding state by covering with a lid, and after the lower lid is removed from the container body at the time of bait exchange, the connecting cylinder is connected to the lower end of the container body via the upper connecting part. Connected to the lower end opening is covered with the lower lid The upper end of the container body of another body breeding bed is filled in part, and is configured to couple to the connecting portion of the lower portion of the connecting cylinder.

  According to the first aspect of the present invention, when the bait is exchanged, the connecting cylinder is removed from the lower end of the container body, the lower lid is removed from the removed connecting cylinder, and the upper part of the connecting cylinder is connected to the container body. Reconnect to the lower end of the container, and connect the upper end of the container body filled with breeding floor containing new bait to the lower part of the connection cylinder to connect the lower new container body to the upper old container body Can be connected through the body. As a result, the larvae on the breeding floor in the upper container body have the habit of moving downward by themselves when they eat up the food, so after moving to the lower end of the upper breeding floor, A small space corresponding to the thickness falls and enters the new breeding floor below. Therefore, since the larva moves by itself from the accustomed growth environment of the upper old breeding floor to the new breeding floor of the lower similar breeding environment, it contains the uneaten food in the container body as before. Unlike taking out the larvae by breaking the rearing floor after taking out all the rearing floors and the growing larvae together from the container, the growing environment will not be destroyed, so there will be no stress . Therefore, it is extremely unlikely that the larvae will stop growing or that the larvae will not grow to the expected size.

  Moreover, the bait exchange can be performed without taking out the larvae from the container body and without touching the hands of the breeder, so that there is no possibility that the pests such as fungi and mites adhere to the larvae. Furthermore, the transfer to the new container body is completed simply by removing the lower lid of the connecting cylinder removed from the old container body and then connecting the new container body to the old container body via the connecting cylinder. Therefore, the troublesome work of taking out all of the breeding floor and the growing larvae from the container as in the conventional case is unnecessary, and the work efficiency is remarkably improved.

  According to the invention which concerns on Claim 2, a lower cover body can be removed from a connection cylinder body only by pressurizing the lower cover body integrally formed in the connection cylinder body, and fracture | rupture an easily breakable part. Further, since the lower lid is integrally formed with the connecting cylinder, the number of parts is reduced and management is facilitated.

  According to the third aspect of the invention, the lower lid can be removed from the connecting cylinder without performing the breaking operation for removing the lower lid, and the lower lid can be reused many times. There is.

  According to the invention which concerns on Claim 4, a container main body, an upper cover body, and a connection cylinder can be attached or detached easily by easy operation.

According to the fifth aspect of the present invention, a very narrow vent hole is formed between the ventilation groove and the container main body, so that it is possible to effectively prevent pests such as mushrooms from entering the container main body. Since both the upper and lower ends of the container body can be communicated with the outside air while preventing the light alcohol content among the various gas components generated with the deterioration of the breeding floor, it passes through the ventilation groove of the upper lid. In addition to being discharged to the outside, heavy CO _{2 and the} like are discharged to the outside through the ventilation groove of the connecting cylinder, so that the breeding floor can always be kept in an environment suitable for insect growth.

  According to the invention which concerns on Claim 6, the removal operation | work from the connection cylinder body of a lower cover body and the attachment or detachment operation | work with respect to the connection cylinder body of a lower cover object become unnecessary, and the lower cover body with which the container main body currently raised is mounted | worn There is an advantage that only needs to be removed.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, exemplary embodiments of the invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view showing an insect breeding container according to the first embodiment of the present invention. In this embodiment, a breeding container is shown that is configured so that the most popular and marketable beetle can be raised from the larva stage to grow into a healthy larva. Therefore, hereinafter, breeding of stag beetles will be described. This breeding container is formed into a cylindrical shape by resin molding, filled with a breeding floor, which will be described later, and a container main body 1 into which larvae are placed, and a resin upper lid that covers the upper end opening of the container main body 1 2 and the resin connecting cylinder 3 that covers the lower end opening of the container body 1 constitute one unit, and a plurality of these units are provided.

  The container body 1 has male screw portions 4 and 7 formed on the outer peripheral surfaces near the upper end opening and the lower end opening, respectively, and the upper and lower male screw portions 4 and 7 have the same thread groove shape. The upper lid 2 is formed with ventilation grooves 8 at four equally spaced locations on the inner peripheral surface of the side wall. The connecting cylinder 3 is integrally formed with a lower lid body 9 at the center in the vertical direction of the inner surface, and the internal threads on both the upper and lower sides of the lower lid body 9 can be screwed with male threads 4 and 7. A portion 10 (the lower female screw portion is not shown) is formed, and ventilation grooves 12 and 13 are formed in the shape obtained by deleting the upper and lower female screw portions 10 at four equally spaced locations on the inner peripheral surface. .

  FIG. 2 is a longitudinal sectional view showing a beetle rearing state in which the upper end opening of the main body cylinder portion 1 of FIG. 1 is covered with the upper lid 2 and the connecting cylinder 3 is connected to the lower end opening. The female threaded portion 10 at the upper part of the connecting cylinder 3 is screwed into the male threaded part 7 near the lower end of the container main body 1, and the connecting cylinder 3 is connected to the lower end of the container main body 1. Thereby, the bottom end opening of the container body 1 is covered with the lower lid body 9 to form a bottomed cylindrical breeding container, and the breeding container 14 is filled with the breeding floor 14 being compressed and compressed. And a female screw part 17 formed on the inner peripheral surface of the side peripheral wall of the upper lid body 2 is screwed into the male screw part 4 near the upper end of the container main body 1, and the container main body 1 is screwed. The upper end opening of 1 is covered with the upper lid 2.

As the breeding floor 14, it is common to use a mat that is fermented with appropriate moisture and blended with nutrients necessary for larvae in deciduous wood flakes such as cucumber and beech. However, in this embodiment, as described above, the breeding container for the stag beetle is illustrated, and therefore, the breeding floor 14 suitable for breeding the stag beetle will be described. The first way to make the breeding floor 14 is to make a medium mixed with sawdust, rice bran, soft flour, minerals, etc., adjust the medium moisture to 55-75% and fill it in the breeding container, 118-120 ° C. Is added for 30 to 40 minutes to sterilize miscellaneous bacteria that adversely affect the mycelia, and then mushroom seeds are seeded and the mycelium is cultured while maintaining the temperature, humidity, and CO ₂ concentration at predetermined values. A second method of making the breeding floor 14 is a method in which the mycelial bed block (also available on the market) that has undergone mycelial cultivation is broken and compressed into a breeding container and filled. In this second method, the sterilization process for removing germs that adversely affect the mycelium has already been completed in the production stage of the mycelia block, so that the container body 1, the upper lid 2 and the connecting cylinder 3 are sterilized. This is preferable because it is not necessary to use a material that can withstand a temperature of 118 to 120 ° C.

  The outer peripheral end portion of the lower lid body 9 of the breeding container is connected to the inner peripheral surface of the central portion in the vertical direction of the connecting cylinder 3 through the easily breakable portion 18 that is thin and ring-shaped. Are integrally formed. The easily breakable portion 18 is set to a strength that can reliably support the breeding floor 14 filled in the breeding container and can be easily broken by pressing with a finger or tapping with a hammer lightly. When the easily breakable portion 18 is set to a relatively high strength that is broken by lightly tapping with a hammer, the breeding floor 14 can be pressurized and filled while the connecting cylinder 3 is connected to the container body 1. On the other hand, when the easily breakable portion 18 is set to a relatively low strength that is broken when pressed with a finger, the support block 14 is inserted into the space below the lower lid 9 in the connecting cylinder 3 and then the breeding floor 14 If the container body 1 with the connecting cylinder connected to the lower end portion is turned upside down, the breeding floor 14 is pressurized and filled from the lower opening of the container body 1. Is not added to the lower lid 9 of the connecting cylinder 3, so that the breeding floor 14 can be filled without any trouble.

Further, the upper end portion of the rearing container communicates with the outside through the four ventilation grooves 8 of the upper lid body 2, and the lower end portion is communicated with the outside through the ventilation groove 12 on the upper portion of the connecting cylinder 3. Communicate. That is, each of the ventilation grooves 8 and 12 extends slightly upward and downward slightly longer than the female screw portions 17 and 10 in which the ventilation grooves 8 and 12 are formed, and the upper plate 2 and the upper end opening surface of the container main body 1. And the gap between the bottom plate portion of the lower lid plate 9 and the upper end opening surface of the container main body 1. A very narrow vent hole is formed between the vent grooves 8 and 12 and the container body 1, so that the container body 1 can be effectively prevented from invading pests such as mushroom flies into the breeding container. The upper and lower ends can be communicated with the outside air. Various kinds of gas components are generated on the breeding floor 14 as it deteriorates. However, since the upper and lower ends of this breeding container communicate with the outside air, the light alcohol content of the produced gas components is While being discharged to the outside through the ventilation groove 8 of the upper lid 2, heavy CO _{2 and the} like are discharged to the outside through the ventilation groove 12 at the upper part of the connecting cylinder 3. Therefore, the inside of the breeding floor 14 is always maintained in an environment suitable for the growth of the stag beetle. In addition, the internal thread part 11 and the ventilation groove | channel 13 of the lower part of the connection cylinder 3 do not fulfill | perform a function in the breeding state of FIG.

  The larvae of the stag beetle are placed in the breeding container configured as shown in FIG. 2 and the larvae are transferred to the breeding container filled with the breeding floor 14 containing new food in order to exchange the food every two to three months. If this bait exchange is performed 3 to 4 times in about one year, the larvae will molt into 2nd and 3rd larvae (final larvae). As soon as it reaches the stage of hatching, an oval chamber is created, and males emerge and become adults in about one month.

  A procedure for bait exchange will be described. As shown in FIG. 3, first, the connecting cylinder 3 is turned to release the screwing of the upper female thread 10 of the upper connecting cylinder 3 with respect to the lower male thread 10 of the container body 1. Is removed from the container body 1. At this time, since the breeding floor 14 is compressed and filled in the breeding container and is in a solidified state, the breeding floor 14 is held in the container body 1 as it is and does not fall downward. Subsequently, the lower lid body 9 of the removed connecting cylinder 3 is pushed with a finger to break the easily breakable portion 18, so that the lower lid body 9 is separated from the connecting cylinder 3 and removed as indicated by a two-dot chain line. .

  Next, as shown in FIG. 4, the connecting cylinder 3 from which the lower lid body 9 is removed is screwed with the upper female threaded portion 10 of the connecting cylindrical body 3 to the lower male threaded portion 7 of the container main body 1. Reconnect to the lower end. Subsequently, the upper lid 2 of the breeding container filled with the breeding floor 14 containing new food and stored in the state shown in FIG. 2 is removed from the container main body 1 and the upper part of the container main body 1 of this new breeding container. By screwing the male screw part 4 into the female screw part 11 at the lower part of the connecting cylinder 3, the container body 1 of the lower new breeding container is connected to the container body 1 of the upper old breeding container via the connecting cylinder 3 This completes the bait exchange. In other words, since the larvae on the rearing floor 14 in the upper old rearing container have the habit of moving downward by themselves when they eat up the food, after moving to the lower end of the upper old rearing floor 14, A small space corresponding to the thickness of the lower lid body 9 is dropped and enters the new breeding floor 14 below by itself.

  Therefore, since the larva moves by itself from the living environment in which the old rearing floor 14 is accustomed to living to the new rearing floor 14 in the lower same growing environment, the food left over in the rearing container as in the conventional case. Unlike taking out the larvae by breaking the rearing floor after taking out all the rearing larvae together with the growing larvae from the container and taking out the larvae, they will not be in a situation where the growth environment is destroyed, so they are stressed There is no. Therefore, it is extremely unlikely that the larvae will stop growing or that the larvae will not grow to the expected size. The fact that this effect is obtained has been confirmed by the applicant as a result of actually raising a large number of larvae to adults. In addition, the bait exchange can be performed without taking out the larvae from the breeding container and without touching the hands of the breeder. Therefore, there is an advantage that there is no possibility that the larvae or the pests such as mites adhere to the larvae. Furthermore, the transfer to a new breeding container is performed by breaking and removing the lower lid 9 of the connecting cylinder 3 removed from the old breeding container, and then replacing the new breeding container with the old breeding container via the connecting cylinder 3. Since it completes only by connecting, the troublesome operation | work which takes out all the breeding beds and the growing larva from a container like the conventional one becomes unnecessary, and working efficiency improves markedly.

  If it can be confirmed that the larva has moved from the old rearing floor 14 to the lower new rearing floor 14, the upper connecting cylinder 3 of the two connecting cylinders 3 in FIG. The upper container body 1 is excluded, and the upper end opening of the container body 1 of the lower breeding container is covered with the upper lid 2. That is, the breeding container has the same form as that shown in FIG. As a result, it is possible to protect the larvae by eliminating the adverse effects caused by the toxic gas generated with the deterioration of the old bait in the breeding floor 14 of the upper breeding container. Since the container body 1 of the removed upper rearing container has a cylindrical shape with both ends opened in the tube center direction, the inner breeding floor 14 can be easily taken out by removing the upper lid body 2 and the connecting cylinder body 3. Can be cleaned easily and reused easily.

  After the above-described bait exchanging operation is repeated 2-3 times, when the bait is replaced after the larvae become the third instar larvae, as shown in FIG. To the container body 1 of the old breeding container. A part of the bottom surface of the container main body 19 and a part of the side peripheral surface rising from the bottom surface is covered with a failure to prevent emergence failure sheet 20 having a rough surface. The emergence failure prevention sheet 20 is described in detail in the aforementioned Patent Document 1. By laying the emergence failure prevention sheet 20, since the surface of the failure emergence prevention sheet 20 is rough, it becomes easy to smear feces when hatching, and a healthy chamber is easily created, Moreover, when it emerges, it is possible to secure a scaffold on the rough surface of the emergence failure prevention sheet 20, so that it can enter an emergence behavior with a correct posture and grow into an adult with a healthy posture without causing the emergence failure.

  FIG. 6 is a longitudinal sectional view at the time of completion of the bait exchanging work of the breeding container according to the second embodiment of the present invention. This embodiment is different from the first embodiment only in that the failure to prevent failure 9a made of spiral protrusions is integrally formed on both surfaces of the lower lid body 9 of the connecting cylinder 3. In the second embodiment, the failure to prevent emergence prevention part 9a formed integrally with the lower lid 3 has a function equivalent to that of the failure to prevent failure emergence sheet 20 shown in FIG. Even if it cannot be determined accurately, a healthy cocoon is created by the presence of the emergence failure prevention unit 9a, and it can grow into an adult with a healthy posture without causing emergence failure. Therefore, if the connecting cylinder 3 having the lower lid body 9 having the emergence failure prevention portion 9a of the second embodiment is connected at an early stage, the larva grows into the third instar larva. Since it could not be distinguished, the timing of connecting the bottomed cylindrical container body 19 in which part of the bottom surface and the side peripheral surface of FIG. It is possible to prevent the occurrence of defects. Further, it is not necessary to separately prepare a bottomed cylindrical container body 19 covered with the emergence failure prevention sheet 20, and the number of parts is reduced and management is facilitated.

  Moreover, the breeding container of 1st Embodiment connects the two container main bodies 1 each filled with the breeding floor 14 containing a new bait up and down like the form shown in FIG. If the larvae of the stag beetle are placed in the breeding floor of the upper container body 1, the stag beetle that is fed in large quantities can be bred very suitably. Furthermore, if the breeding container of 1st Embodiment connects the 3 or more container main bodies 1 by the arrangement | positioning which piles up and down through the connection cylinder 3, it will put a larva in each container main body 1, respectively. Many larvae can be raised simultaneously in a small space.

  FIG. 7: is a longitudinal cross-sectional view at the time of completion | finish of the bait | feed exchange operation | work of the breeding container based on 3rd Embodiment of this invention. This embodiment differs from the first embodiment in that, in the first embodiment, the detachable mounting structure of the container body 1, the upper lid body 2 and the connecting cylinder body 3 is a screw connection. In this embodiment, it is only a configuration that is detachably coupled in a press-fitting form. That is, the upper lid body 22 and the connecting cylinder body 23 are not formed with the female screw portions 17, 10, and 11 as in the first embodiment, and the container main body 21 has the male screw portion 4 as in the first embodiment. , 7 are not formed. However, the lower lid body 9 similar to that of the first embodiment is integrally formed on the connecting cylinder body 23 via the easily breakable portion 18, and the ventilation groove 8 similar to that of the first embodiment is formed on the upper lid body 22. In the connecting cylinder 23, communication grooves 12 and 13 similar to those in the first embodiment are formed.

  And in this 3rd Embodiment, the outer peripheral surface of the upper and lower openings vicinity of the container main body 21 is each formed in the taper surface which diameter-reduces slightly toward an opening end, and the lower cover body 9 of the upper cover body 22 and the connection cylinder 23 On the other hand, the upper and lower outer peripheral surfaces are respectively formed as tapered surfaces that expand in diameter toward the opening end, so that the upper lid body 22 and the connecting cylinder body 23 can be easily coupled to the vicinity of the upper and lower opening surfaces of the container body 21 in a press-fitted form. It has become. Therefore, also in this third embodiment, the same effect as described in the first embodiment can be obtained.

  FIG. 8 is a longitudinal sectional view showing the connecting cylinder 24 in the breeding container according to the fourth embodiment of the present invention. As in the second embodiment of FIG. 6, the connecting cylinder 24 is configured such that the container main body 21 is coupled from above and below in a press-fitted form, and the difference from the second embodiment is that the lower lid 27. Is not formed integrally with the connecting cylinder 24 but is provided separately, and the outer peripheral edge of the lower lid 27 is formed slightly thin at a position closer to the lower side than the center of the connecting cylinder 24 in the vertical direction. It is only the structure by which the support ring piece 28 which supports the cyclic | annular to-be-supported part 29 from a downward | lower direction is integrally projected toward inward. Since the breeding floor 14 filled in the container main body 21 is placed on the upper surface, the lower lid 24 of the breeding container of this embodiment is sandwiched from above and below by the breeding floor 14 and the support ring piece 28 and is stably held. At the same time, when the connecting cylinder 24 is removed from the container main body 21 during the bait exchange, the connecting cylinder 24 is removed without performing the breaking operation for removing the lower lid 9 as in the first and second embodiments. There is an advantage that the lower lid 27 can be reused many times while being easily removed by simply pulling it up.

  FIGS. 9A to 9C are vertical cross-sectional views showing the relative arrangement of the respective components when performing the feed exchange of the breeding container according to the fifth embodiment of the present invention. (A) Covers the upper end opening of the container main body 1 with the upper lid 2 that is screwed onto the upper end of the container main body 1 as in the first embodiment, and the lower lid has the same shape as the upper lid 2.
