Description

[Technical Field]

[0001] One embodiment of the present invention relates to the construction of an apparatus for rearing insects and insect larvae. [Background technology]

[0002] Containers for raising insects or insect larvae generally have a container body and a lid body that is attached to the container body in a detachable or openable manner, and have a structure in which ventilation holes are provided in one or both of the container body and the lid body (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-017204 Summary of the Invention [Problem to be solved by the invention]

[0004] When raising insects or insect larvae, it is necessary to feed them. To feed them, it is necessary to open the lid or door on the container in which the insects or insect larvae are raised. When the lid or door is opened, the internal space of the container is connected to the external space outside the container, so there is a risk that the insects or insect larvae being raised will escape into the external space. In particular, flying insects fly freely in the space, so opening the lid or door carelessly may cause them to fly into the external space. Therefore, great care must be taken when feeding them. [Means for solving the problem]

[0005] An insect and insect larvae rearing device according to one embodiment of the present invention comprises a rearing container that separates the internal space for rearing insects from the outside world, a feeding hole provided in a part of the rearing container, and a feeder that is provided so as to contact the feeding hole from the outside of the rearing container.

[0006] In one embodiment of the present invention, the rearing container may have a feeding section that protrudes into the interior space and has a feeding hole provided in the feeding section. Alternatively, the rearing container may have a feeding section that protrudes outward from the interior space and has a feeding hole provided in the feeding section.

[0007] In one embodiment of the present invention, the rearing container has a floor, walls, and a ceiling, and the feeding unit may be provided on any one of the floor, walls, and ceiling. For example, the rearing container may have at least a floor, and a feeding hole may be provided on the floor.

[0008] In one embodiment of the present invention, the size of the feeding hole is preferably smaller than the body size of the insect and is large enough to allow the insect to eat food with its mouthparts. If the insect is a Diptera insect, the size of the feeding hole is preferably smaller than the body size of the Diptera insect and is large enough to allow the insect to eat food with its proboscis. The feeding hole may be made of mesh.

[0009] In one embodiment of the present invention, the feeder may include a water-absorbent foamed resin body and a tray that supports the foamed resin body, and the foamed resin body may be sized to fit into the feeding section. The feeder may also include a sheet material to which the feed is attached and a holding member that abuts the sheet material against the feeding hole. [Effects of the Invention]

[0010] According to one embodiment of the present invention, a breeding device for insects and insect larvae is provided in the breeding container, and a feeder is provided outside the breeding container so that it is in contact with the feeding hole, so that feeding can be carried out without opening the lid or door of the breeding container, and the insects being raised can be prevented from scattering to the outside.

[0012] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention can be implemented in many different forms, and should not be construed as being limited to the description of the embodiments exemplified below. For clarity of explanation, the drawings may show the length, width, height, thickness, shape, etc. of each part schematically compared to the actual form, but these are merely examples and do not limit the interpretation of the present invention. Furthermore, in this specification and each drawing, elements similar to those previously described with reference to the previous drawings may be designated by the same reference numerals (or reference numerals with A, B, etc. suffixed thereto), and detailed description may be omitted as appropriate. Furthermore, the letters "first" and "second" attached to each element are convenient labels used to distinguish each element and have no further meaning unless otherwise specified.

[0013] FIG. 1 shows a perspective view of a breeding device 100 for insects and insect larvae according to one embodiment of the present invention. In the following description, the breeding device 100 for insects and insect larvae will be simply referred to as the "breeding device 100." The breeding device 100 has a breeding container 102 that separates an internal space 101 for breeding insects from an external space. The breeding device 100 has a feeder 104 installed outside the breeding container 102. Examples of insects that can be raised in the breeding device 100 include insects belonging to the order Diptera and their larvae (houseflies, black soldier flies, etc.), insects belonging to the order Orthoptera and their larvae (crickets, grasshoppers, katydids, etc.), and insects belonging to the order Lepidoptera and their larvae.

[0014] FIG. 1 shows an example of a breeding container 102 that includes a floor 1022, a ceiling 1024, walls 1026, and supports 1028 supporting these components. The breeding container 102 may have ventilation holes in the floor 1022, ceiling 1024, and parts of the walls 1026 to ensure ventilation and lighting. The ventilation holes may be small holes in the plate-like members that form the floor 1022, ceiling 1024, and walls 1026, or may be formed by mesh (netting) that forms part or all of the floor 1022, ceiling 1024, and walls 1026. There are no limitations on the size of the ventilation holes (the size of the mesh openings), but they are preferably large enough to prevent the insects or insect larvae being raised from escaping to the outside. For example, when raising insects of the order Diptera, the ventilation holes preferably have a size of 0.5 mm to 1.0 mm. When the ventilation holes are formed with a mesh, the mesh opening size is preferably 18 to 35 mesh (based on JIS Z 8801).

[0015] Although FIG. 1 shows the rearing container 102 as having a hexahedral shape, the shape of the rearing container 102 is not limited. The structure and shape of the rearing container 102 may omit the support 1028, or the floor 1022, ceiling 1024, and part of the wall 1026 may be replaced with mesh, giving the rearing container 102 any shape, such as a sphere, a cone, or a cylinder. The size of the rearing container 102 is not limited and can be selected appropriately depending on the type and number of insects and insect larvae to be reared. For example, the rearing container 102 may be large enough to be placed on a table, large enough to be installed indoors, or large enough for an operator to enter and work inside.

[0016] Although not shown in FIG. 1, the breeding container 102 may be provided with a lid or door, and portions of the ceiling 1024 and wall 1026 may have a removable structure.

[0017] A feeding section 103 is provided in the breeding container 102. The feeding section 103 is provided so as to protrude into the internal space 101 of the breeding container 102. A feeding hole 1032 is provided in the feeding section 103. The feeding hole 1032 is a small hole that connects the internal space 101 of the breeding container 102 with the external space outside the breeding container 102. The feeding hole 1032 is a hole for providing food (food) to insects and insect larvae being raised in the breeding container 102. Figure 1 shows a structure in which the feeding section 103 is provided so as to protrude from the floor 1022 of the breeding container 102 into the internal space 101, and the feeding hole 1032 is provided in the feeding section 103.

[0018] Feeding unit 103 may be formed from a plate-like member, or may be formed partially or entirely from a mesh-like member. Feeding holes 1032 are preferably provided on a portion or the entire surface of feeding unit 103. When feeding unit 103 is formed from a plate-like member, feeding holes 1032 are formed as small holes opened in the plate-like member. When feeding unit 103 is formed from a mesh-like member, feeding holes 1032 may be formed by openings in the mesh.

[0019] The feeding hole 1032 is large enough to prevent the insects or insect larvae being reared from escaping to the outside, and has a diameter that allows the insects or insect larvae to use their mouthparts or proboscis to consume food. For example, when the insects are Diptera or Lepidoptera, the feeding hole 1032 is preferably smaller than the insect's body and has a diameter that allows the insects to consume food using their proboscis. Specifically, when rearing Diptera insects, the feeding hole 1032 preferably has a diameter of 0.5 mm to 1.0 mm. When the feeding hole 1032 is made of mesh, the mesh opening size is preferably 18 mesh to 35 mesh (based on JIS Z 8801).

[0020] The feeder 104 is a device for providing food (i.e., bait) to insects or insect larvae from outside the rearing container 102 via the feeding unit 103. The feeder 104 has a shape and structure that corresponds to the type of food (liquid, solid, semi-solid). For example, as shown in FIG. 1, the feeder 104 has a shape that allows it to be inserted into the feeding unit 103 from outside the rearing container 102.

[0021] In the example shown in FIG. 1 , feeder 104 has feed offering surface 1042 formed at the portion inserted into feeding unit 103. When feeder 104 is formed from a plate- or sheet-like member, feed offering surface 1042 may be coated with paste-like feed. In this case, the surface of the plate- or sheet-like member is preferably roughened or corrugated so that the paste-like feed adheres easily and does not run off. Alternatively, feeder 104 may be formed from a water-absorbent foamed resin (also called a sponge). In this case, feed offering surface 1042 may be formed from the surface of a sponge that has absorbed liquid feed.

[0022] As shown in FIG. 1 , feed (food) can be provided to the insects and insect larvae being reared by inserting a feeder 104 into a feeding section 103 that protrudes into the internal space 101 from the outside of the rearing container 102. That is, since the feeder 104 is installed outside the rearing container 102 and the feeding section 103 is configured to provide feed (food) to the insects and insect larvae being reared, there is no need to open the lid or door of the rearing container 102 when feeding. This prevents the insects and insect larvae from escaping from the rearing container 102 to the external space when feeding. In particular, when the insects being reared are flying insects, there is a concern that the insects will fly out if the door of the rearing container 102 is opened carelessly. However, according to the rearing device 100 of this embodiment, feed (food) can be provided to the rearing container 102 from the outside, preventing the flying insects from scattering.

[0023] It should be noted that the breeding apparatus 100 according to this embodiment is not limited to the structure shown in Fig. 1. Several examples of the breeding apparatus 100 are given below.

[0024] FIG. 2(A) shows the cross-sectional structure of the breeding apparatus 100. The cross-sectional structure shown in FIG. 2(A) corresponds to the structure of the breeding apparatus 100 shown in FIG. 1. The breeding apparatus 100 has a breeding container 102 that forms an internal space 101 for breeding insects or insect larvae, and a portion of a feeder 104 is inserted into a feeding section 103. FIG. 2(A) also shows a structure in which a wall 1026 of the breeding container 102 is formed of mesh. The mesh that forms the wall 1026 functions as an air vent. Note that mesh may also be applied to part or all of the floor 1022 and ceiling 1024 of the breeding container 102.

[0025] Feeding unit 103 is provided so as to protrude upward from floor 1022. Feeding unit 103 is provided so as to cover an opening provided in floor 1022. There is no limit to the height to which feeding unit 103 protrudes, and it may have a height that reaches ceiling 1024. Feeding unit 103 has the function of separating internal space 101 of breeding container 102 from the outside of breeding container 102. Feeding unit 103 forms a recess in the exterior of breeding container 102 when floor 1022 is viewed from below (when the floor is viewed from the outside).

[0026] The feeder 104 is inserted into a recess formed by the feeding unit 103. In order to insert the feeder 104 into the feeding unit 103 from the underside of the floor 1022, it is preferable that the floor 1022 be located at a higher position than the installation surface (the surface that serves as the base for installation, such as the ground or the floor of a building). The height of the floor 1022 can be adjusted by extending the support 1028 (see FIG. 1) below the floor 1022 or by extending the members that make up the wall 1026 below the floor 1022. In this way, by configuring the floor 1022 of the breeding container 102 to be elevated, the feeder 104 can be placed below the floor 1022, forming a work space for supplying feed (food).

[0027] Although not shown, the rearing container 102 may have a structure in which the floor 1022 is in contact with the installation surface. In the case of such a structure, the entire rearing container 102 can be lifted up and placed over the feeder 104, thereby allowing the feeder 104 to be inserted into the feeding section 103.

[0028] Feeding section 103 is provided with feeding holes 1032. The position of feeding holes 1032 is arbitrary, and they may be provided on a part or the entire surface of feeding section 103. For example, as shown in FIG. 2(A), feeding holes 1032 may be provided on the side and top surface of feeding section 103, thereby providing feeding opportunities for insects and insect larvae being raised.

[0029] FIG. 2(A) shows an example of feeder 104 composed of absorbent foamed resin 1044 and tray 1045. Foamed resin 1044 is placed inside tray 1045, with its upper portion inserted into feeding unit 103, and has a structure and size such that the outer surface of the inserted portion contacts or is close to feeding hole 1032. Foamed resin 1044 may be provided in contact with the outer surface of feeding unit 103, or may be provided with a small gap. The surface of foamed resin 1044 adjacent to feeding hole 1032 becomes feed (feed) presentation surface 1042.

[0030] Liquid feed is used as the feed. The liquid feed is a liquid containing protein or carbohydrate, and can be, for example, milk, soy milk, powdered milk, skim milk, a solution of dissolved sugar or protein, or a mixture of two or more of these. The liquid feed may be pre-soaked into the foamed resin body 1044. Alternatively, the liquid feed may be placed in the tray 1045. In this case, the foamed resin body 1044 is placed so that its lower portion is immersed in the liquid feed in the tray 1045. The liquid feed can be spread throughout the foamed resin body 1044 by capillary action, allowing for a continuous supply of feed. This configuration of the feeder 104 is suitable for raising insects with elongated mouthparts or proboscises.

[0031] 2(A) can supply food from outside the rearing container 102 using the feeder 104, eliminating the need to open the lid or door of the rearing container 102 and preventing insects and insect larvae from escaping to the outside during feeding. The rearing device 100 is configured so that the feeder 104 is inserted into the feeding section 103 from below the floor 1022, eliminating the need for the rearing container 102 to support the feeder 104, thereby stabilizing the installation state and preventing the rearing container 102 from tipping over, for example.

[0032] 2(B) shows the configuration of a breeding device 100 in which a feeder 104 is provided on the ceiling 1024 side of a breeding container 102. The components constituting the breeding container 102 are similar to those in the example shown in FIG. 2(A), but the breeding container 102 shown in FIG. 2(B) has a structure in which the feeding unit 103 protrudes from the ceiling 1024 of the breeding container 102 into the internal space 101.

[0033] Feeding section 103 is provided with feeding hole 1032. Feeder 104 is provided so as to be inserted into feeding section 103. FIG. 2(B) shows an example in which feeder 104 is composed of foamed resin body 1044 and tray 1045. Tray 1045 is placed on top of foamed resin body 1044, and may have a structure in which liquid feed (food) seeps out from pores provided in the bottom surface of tray 1045.

[0034] Solid feed may be used in place of foam resin 1044 in feeder 104. In this case, instead of using feeder 104, solid feed is directly introduced into a recess in ceiling 1024 formed by feeding unit 103 (the recess formed when rearing container 102 is viewed from the outside). Even when solid feed is directly introduced into feeding unit 103, it can be provided to the insects and insect larvae being reared through feeding hole 1032 by coming into contact with the bottom and side surfaces of feeding unit 103. In this case, a lid may be provided on the outside of rearing container 102 to close feeding unit 103 to prevent pests from approaching from the outside.

[0035] The breeding device 100 shown in Figure 2(B) is suitable for cases where the height of the breeding container 102 is shorter than the height of the operator, and feeding operations can be performed from the top of the breeding container 102, thereby improving workability.

[0036] Figure 3(A) shows the configuration of a breeding device 100 in which a feeder 104 is provided on the wall 1026 side of a breeding container 102. The components that make up the breeding container 102 are the same as those in the example shown in Figure 2(A). The breeding container 102 shown in Figure 3(A) has a structure in which the feeding section 103 protrudes from the wall 1026 into the internal space 101.

[0037] Similar to the example shown in FIG. 2(A), feeding section 103 is provided with feeding holes 1032. The number and location of feeding holes 1032 are arbitrary, and they can be provided on the top, side, or bottom of feeding section 103. While FIG. 3(A) shows only foamed resin body 1044 as the configuration of feeder 104, a tray 1045 may also be attached. Alternatively, solid feed may be used instead of foamed resin body 1044, and the solid feed (bait) may be directly placed in a recess in wall 1026 formed by feeding section 103 (the recess formed when rearing container 102 is viewed from the outside). In this case, a lid may be provided on the outside of rearing container 102 to close feeding section 103 so that pests are not attracted by the feed (bait) from the outside.

[0038] 3(A), the feeding section 103 can be provided at an appropriate height on the wall 1026. This allows an operator to perform feeding work from the side of the breeding container 102 regardless of the height of the breeding container 102, thereby improving workability.

[0039] FIG. 3(B) shows an example of a feeder 104 having a configuration different from those shown in FIGS. 2(A) to 3(A). The feeder 104 shown in FIG. 3(B) is composed of a plate-shaped member 1046 and a support member 1047 that supports the plate-shaped member 1046. The plate-shaped member 1046 is held upright by the support member 1047 so as to be close to the surface of the feeding unit 103 facing the outside world. Feed is attached to the surface of the plate-shaped member 1046, and this surface serves as the feed presentation surface and is positioned so as to be in contact with or close to the feeding hole 1032. The surface of the plate-shaped member 1046 may be smeared with paste-like feed, or a sheet-like solid feed may be attached to the surface of the plate-shaped member 1046. Alternatively, the plate-shaped member 1046 may be made of a thick paper material and soaked in liquid feed. Paste-like feed (bait) can be, for example, a solution of solids such as milk, soy milk, powdered milk, skim milk powder, sugar, or protein, or a paste made by mixing a binder such as potato starch with a mixture of these, yogurt, etc. Also, solid feed (bait) can be, for example, powdered milk, skim milk powder, sugar, or protein.

[0040] By forming plate-like member 1046 from a flexible material, it can be adapted to the shape of feeding unit 103. As shown in FIG. 1, if feeding unit 103 has a cubic shape, flat plate-like member 1046 can be attached to each surface. If feeding unit 103 has a cylindrical shape, curved plate-like member 1046 can be attached to fit the curved surface of the cylinder. Furthermore, plate-like member 1046 may be replaced with a rod-like member with feed attached to its surface, instead of a plate-like or sheet-like member.

[0041] Plate-like member 1046 with feed attached thereto can be easily installed using support member 1047, making it easy to replace the feed. When feeding unit 103 is provided on ceiling 1024 as shown in FIG. 2(B), plate-like member 1046 may be provided so as to be suspended from above rearing container 102. Furthermore, when feeding unit 103 is provided on wall 1026 of rearing container 102 as shown in FIG. 3(A), plate-like member 1046 may be provided so as to be inserted into feeding unit 103.

[0042] In the breeding apparatus 100 shown in FIG. 3(B), the feeder 104 is made of a plate-shaped member, which makes it easy to install in the feeding section 103 and also makes it easy to replace.

[0043] 2(A) and 2(B) and 3(A) and 3(B), the feeding section 103 provided in the breeding container 102 is not limited to one location, but may be provided in multiple locations. Also, multiple feeding sections 103 may be provided in different locations, such as between the floor 1022 and the ceiling 1024, between the floor 1022 and the wall 1026, or between the ceiling 1024 and the wall 1026.

[0044] 2(A) to 3(B) show a structure in which feeding unit 103 protrudes into interior space 101 of breeding container 102, but the configuration of feeding unit 103 is not limited to this. For example, as shown in FIG. 4, feeding unit 103 may be provided so as to protrude outside breeding container 102. In this configuration, feeder 104 is disposed outside feeding unit 103. That is, foamed resin body 1044 constituting feeder 104 is disposed so as to contact feeding hole 1032 from the outside, thereby forming feed (food) providing surface 1042. Tray 1045 for supplying feed (food) may be provided on the top or side of foamed resin body 1044.

[0045] According to the configuration of rearing device 100 shown in Figure 4, it is possible to make the internal space 101 of rearing container 102 larger, and more insects and insect larvae can be reared. Note that while Figure 4 shows an example in which feeding unit 103 is provided on ceiling 1024 of rearing container 102, a configuration in which feeding unit 103 protrudes outward can also be applied to floor 1022 and wall 1026.

[0046] 5(A) and (B) show the configuration of a breeding apparatus 100 in which a feeding hole 1032 is provided in a floor 1022. The feeding hole 1032 may be formed by a mesh (netting) that forms part or all of the floor 1022, as shown in Fig. 5(A), or the feeding hole 1032 may be formed directly in the floor 1022, as shown in Fig. 5(B).

[0047] A container 1048 containing feed (prey) is placed outside the rearing container 102 so as to overlap with the feeding hole 1032 provided in the floor 1022. While there is no limitation on the depth of the container 1048, it is preferable that the container 1048 has a size and height that allows the feed to come into contact with or be close to the feeding hole 1032 when placed inside. The feed placed in the container 1048 may be liquid feed as shown in FIG. 5(A) or solid feed 1049 as shown in FIG. 5(B). Examples of solid feed 1049 that can be used include powdered milk, skim milk powder, solid feed containing sugar, or protein. A platform may be placed under the container 1048 to adjust the height of the container 1048. Although not shown, a foamed resin may be placed in the container 1048 of FIG. 5(A). The foamed resin may be immersed in the liquid feed in the container 1048, with the upper portion in contact with the feeding hole 1032. Also, although not shown, a plate-like member with feed (bait) attached to its surface may be provided so as to contact the feeding hole 1032. Furthermore, although not shown, in FIG. 5(B), a push-up mechanism may be provided under the container 1048 using an elastic member such as a spring to push up the container 1048 from below. With such a push-up mechanism, even if the amount of solid feed 1049 decreases as the insects eat it, the solid feed 1049 can always be placed near the feeding hole 1032 by being lifted up from below.

[0048] 5(A) and (B), the feeding hole 1032 is formed directly in the floor 1022, simplifying the structure of the rearing container 102. As a result, the internal space 101 can be made larger, and the rearing container 102 can be easily cleaned.

[0049] The configuration shown in FIGS. 5(A) and (B) can also be combined with a feeding section 103 that protrudes into the internal space 101 as shown in FIGS. 2(B) and 3(A). [Industrial Applicability]

[0050] By using an insect and insect larvae rearing device according to one embodiment of the present invention, it is possible to improve the efficiency of rearing adult insects during the egg-laying period, particularly in feeding operations. In recent years, with the expansion of the market for insect feed and food, mass production of larvae and pupae, the main raw materials for these insects, has progressed. However, mass production of eggs, the source of larvae and pupae, i.e., rearing adult insects, has become a challenge. In particular, improving the efficiency of feeding adult insects is a challenge in rearing adult insects. This issue stems from the conventional problem of adult insects escaping from rearing containers during feeding operations. By using the present invention to manage adult insects, it is possible to prevent adult insects from escaping from rearing containers and facilitate feeding, thereby improving egg productivity. In particular, when rearing insects belonging to the Diptera order and using them as feed for livestock, farmed fish, or pets, feeding operations can be facilitated and rearing flies can be prevented from escaping. Therefore, when rearing and producing the insects, production management becomes easy and it is possible to avoid affecting the surrounding natural environment and living environment.
