Description

Technical Field

[0001] This utility model relates to the field of parasitic wasp breeding technology, specifically to a device for parasitizing and raising braconid wasps. Background Technology

[0002] Artificial rearing and breeding techniques for braconid wasps are an important method in modern pest control research. As important natural enemies, braconid wasps play a crucial role in studies on their parasitism against various pests such as Lepidoptera and Coleoptera, as well as in the safety assessment of pesticides. Their rearing and parasitic environment is therefore vital. However, existing techniques for testing braconid wasp parasitism mainly involve the host insect, food, and the braconid wasp. These techniques are susceptible to interference during parasitism, such as the escape of the braconid wasp or the inability to promptly replace the host insect's food, thus affecting the final results. This presents challenges to braconid wasp parasitism research, therefore, there is an urgent need to improve the parasitism devices for braconid wasps. Summary of the Invention

[0003] To solve the above problems, this utility model provides a parasitic and rearing device for braconid wasps. This device, by setting up a bee-keeping room, an insect-receiving room and an insect-rearing room connected in sequence, can realize uninterrupted indoor rearing of braconid wasps, unaffected by the external environment.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a parasitic and rearing device for braconid wasps, characterized in that it comprises a beekeeping chamber, an insect receiving chamber, and an insect rearing chamber, all of which are cylindrical structures connected sequentially from top to bottom. The beekeeping chamber has movable doors at both ends. The insect receiving chamber has a first perforated plate at the top. The insect receiving chamber has a support column inside. Several partitions are evenly fixedly connected along the circumference of the support column to divide the insect receiving chamber into compartments with the same number of partitions. Each compartment has an outward-opening door on its side wall. The bottom of each compartment is a pull-out plate. The insect rearing chamber has a second perforated plate at the top. The insect rearing chamber is lined with a soil layer.

[0005] The diameter of the holes in the first perforated plate is 1 mm, and the diameter of the holes in the second perforated plate is 5 mm.

[0006] The lower middle part of the beekeeping room is equipped with a cup for collecting honey water.

[0007] The inner wall and support column of the insect receiving chamber are provided with slots, and the inner wall and support column of the insect receiving chamber are engaged with the partition.

[0008] The outward-opening door has several square holes arranged in a row, and the square holes are covered with a mesh.

[0009] Handles are fixedly installed on the movable door, outward-opening door, and pull-out panel.

[0010] The beekeeping room, the insect receiving room, and the insect rearing room are connected by a threaded structure.

[0011] The thickness of the soil layer is 50 mm.

[0012] The beneficial effects of this utility model are as follows: This utility model connects the beekeeping room, the larvae receiving room, and the larvae rearing room into a whole, reducing manual operation steps. The larvae receiving room is divided into multiple compartments by partitions, which can test the parasitic preferences of braconid wasps for different species of hosts, different foods for the same host, and different treatments for the same food for the same host. The addition of food through the external door avoids the parasitic process of braconid wasps being affected by insufficient food. In addition, the first perforated plate prevents hosts in different compartments from crawling into other compartments, and the second perforated plate separates young parasitic larvae from unparasitized older larvae, avoiding interference with the already parasitized hosts.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0020] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments. Example

[0021] like Figure 1As shown in the figure, this utility model provides a parasitic and rearing device for braconid wasps, including a beekeeping chamber 1, an insect receiving chamber 2, and an insect rearing chamber 3, all of which are cylindrical structures connected from top to bottom. The beekeeping chamber 1 has movable doors 101 at both the top and bottom. The insect receiving chamber 2 has a first perforated plate 201 at the top. The insect receiving chamber 2 has a support column 202 inside. Several partitions 203 are evenly fixedly connected along the circumference of the support column 202 to divide the insect receiving chamber 2 into compartments 204 with the same number of partitions 203. Each compartment 204 has an outward-opening door 205 on its side wall and a pull-out plate 206 at the bottom. The insect rearing chamber 3 has a second perforated plate 301 at the top. The insect rearing chamber 301 is lined with a soil layer 302. By connecting the beekeeping room 1, the insect receiving room 2, and the insect rearing room 3 into a whole, the number of manual operation steps is reduced. The insect receiving room is divided into multiple compartments 204 by the partition 203, which can test the parasitic preferences of braconid wasps for different species of hosts, different foods for the same host, and different treatments for the same food for the same host. Food can be added through the outward-opening door 205, which avoids the parasitic process of braconid wasps being affected by insufficient food.

[0022] In this embodiment, the inner radius of the upper beekeeping chamber 1 is 200mm and the height is 150mm; the inner radius of the middle insect receiving chamber 2 is 200mm and the height is 450mm; and the inner radius of the lower insect keeping chamber 3 is 200mm and the height is 150mm.

[0023] Specifically, the diameter of the holes in the first perforated plate 201 is 1 mm, and the diameter of the holes in the second perforated plate 301 is 5 mm. The holes in the first perforated plate 201 allow only parasitic wasps to pass through while preventing the host from passing through, thus preventing the host from crawling from one section to another. The holes in the second perforated plate 301 allow unparasitized young larvae to pass through, but the young larvae cannot pass through the second perforated plate 301 after they grow up, thus avoiding interference with the already parasitized host.

[0024] Specifically, the lower middle part of the beekeeping room 1 is provided with a cup 102 for holding honey water. The cup 102 can hold 10% honey water, and the adult parasitic wasps are fed with honey water to achieve large-scale propagation of parasitic wasps indoors.

[0025] Specifically, the inner wall of the insect-receiving chamber 2 and the support column 202 are provided with slots, and the inner wall of the insect-receiving chamber 2 and the support column 202 are engaged with the partition 203. By providing slots on the inner wall of the insect-receiving chamber 2 and the support column 202, the partition 203 can be quickly installed and disassembled using the engaging structure, saving installation time.

[0026] Specifically, in order to increase the air permeability of the insect-receiving chamber 2, the outward-opening door 205 has several square holes arranged in a row, and the square holes are covered with a mesh.

[0027] Specifically, handles 4 are fixedly installed on the movable door 101, the outward-opening door 205, and the pull-out panel 206. The handles 4 allow for easy movement of the movable door 101, the outward-opening door 205, and the pull-out panel 206.

[0028] Specifically, the beekeeping chamber 1, the insect receiving chamber 2, and the insect rearing chamber 3 are connected by a threaded structure. This threaded connection allows for a quick and stable connection between the beekeeping chamber 1, the insect receiving chamber 2, and the insect rearing chamber 3.

[0029] Specifically, the soil layer 302 has a thickness of 50 mm. The soil layer 302 is provided to retain moisture or to provide a place for pre-pupae of host insects.

[0030] Workflow: In the upper beekeeping chamber 1, braconid wasps are introduced through the upper movable door 101 and raised in a 10% honey water solution in the cup 102, while maintaining a temperature of 25±1℃ and a humidity of 75±5%. Then, larvae of different hosts are placed into the compartment 204 through the outer opening door 205 of the larval inoculation chamber 2. The lower movable door 101 of the beekeeping chamber 1 is then opened to introduce the braconid wasps into the larval inoculation chamber 2 for larval inoculation. Two days after inoculation, the pull-out plate 206 is actuated so that both parasitized and unparasitized larvae are on the second perforated plate 301. Parasitized larvae hardly move, while unparasitized larvae crawl down into the larval inoculation chamber 3. When they grow up, they cannot pass through the second perforated plate 301, thus avoiding interference with the parasitized hosts.

[0031] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
