Description

Technical Field

[0001] This utility model relates to the field of artificial insect rearing technology, and in particular to a host separation device for the Taiwan Brassicornus. Background Technology

[0002] As an egg-larval parasitic wasp, the Formosanus 'Taiwan's braconid wasp develops its eggs and early larvae within the host. During this stage, it is impossible to distinguish whether the host is parasitized, making early identification extremely difficult. Furthermore, host insects (such as lepidopteran pest larvae) exhibit cannibalistic behavior; when mixed with other insects, unparasitized host insects will prey on parasitized individuals, significantly reducing the parasitism success rate. This is the core biological limitation facing the large-scale breeding of this type of parasitic wasp.

[0003] Current separation methods mainly rely on manual sorting, requiring the host to be manually separated from the parasitic wasp after the host has developed to the third or fourth instar morphology stage. This method is not only time-consuming and labor-intensive, but also requires each rearing box to be individually lined with sawdust substrate and unparasitized hosts to be manually removed, which is very easy to damage the insects. At the same time, a large number of rearing boxes occupy a lot of space, and the sawdust layer must be retained until the wasp emerges, which cannot achieve intensive storage and results in low space utilization.

[0004] Therefore, it is necessary to design a host separation device for the Taiwan Brassicornia hupehensis to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a host separation device for the Taiwan basilicas wasp. This invention is a device that can achieve non-destructive separation based on behavioral differences, thereby improving the breeding efficiency of parasitic wasps.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A host separation device for the Taiwan Braconid wasp includes a box body with a top plate at the top and a breathable mesh. Two openings are located on the right side of the box body. Two mesh pull-out boxes are located inside the box body. A handle is fixedly connected to the right side of each of the two mesh pull-out boxes. The front of each handle extends through a corresponding opening to the outside. A slider is fixedly connected to the lower end of each of the two mesh pull-out boxes. Slide rails that cooperate with the sliders are fixedly connected to the inner walls of the front and rear sides of the box body.

[0008] Preferably, the top plate and the housing are connected by a connecting assembly, which includes connecting blocks fixedly connected to the left and right sides of the housing, and fixing blocks fixedly connected to the left and right sides of the top plate. Bolts are threadedly connected to the two fixing blocks and the corresponding connecting blocks.

[0009] Preferably, two strip plates are fixedly connected to the inner walls of the left and right sides of the box, and multiple guide rods are fixedly connected to the adjacent sides of the two strip plates.

[0010] Preferably, the multiple guide rods are all inclined, and the multiple guide rods located on the left strip plate are staggered with the multiple guide rods located on the right strip plate.

[0011] Preferably, the right inner wall of the box is rotatably connected to two sealing plates.

[0012] Preferably, the breathable mesh is evenly distributed in a honeycomb pattern on the top plate, and the pore size of the breathable mesh is in the range of 0.2 mm.

[0013] Compared with existing technologies, the advantages of this device are:

[0014] 1. Compared with existing technologies, the design of two mesh pull-out boxes is based on the behavioral differences between the host and the parasitic wasp. The non-parasitic host is attracted to the feed and enters the upper layer to feed, while the parasitic host is controlled by the parasitic wasp to migrate downward to the sawdust layer to pupate. No manual screening is required, the sorting accuracy is high, and the problem of low efficiency of manual operation is effectively solved.

[0015] 2. Compared with existing technologies, the use of multiple guide rods makes it easier for the host to climb into the mesh pull-out box above during separation, further improving the separation effect between the parasitic wasp and the host.

[0016] 3. Compared with existing technologies, the sealing plate, through its design, will rotate downwards and close the opening each time the mesh pull-out box is removed, under the action of gravity, preventing non-parasitic hosts from escaping through the opening, while also isolating external dust and insects from entering.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-3 A host separation device for *Condor Heliotropium formosanus* includes a box 1 made of transparent PC material, with a separation chamber inside. A top plate 2 is provided at the upper end of the box 1, and the top plate 2 is sealed to the upper surface of the box 1 by a sealing strip. The top plate 2 has breathable mesh 3, which is evenly distributed in a honeycomb pattern. The pore size of the breathable mesh 3 is 0.2 mm, which is smaller than the minimum body width of an adult *Condor Heliotropium formosanus* (0.3 mm), effectively preventing adult escape. Two openings 4 are provided on the right side of the box 1. Inside the box 1... There are two mesh pull-out boxes 5. The upper mesh pull-out box 5 is used to place feed, and the lower mesh pull-out box 5 is used to lay sawdust substrate. The mesh pull-out boxes 5 are made of 304 stainless steel wire mesh with a mesh size of 10 mesh, which can ensure the passage of insects and prevent sawdust from leaking out. The right side of each mesh pull-out box 5 is fixedly connected to a handle 6. The front side of each handle 6 extends to the outside through the corresponding opening 4. The lower end of each mesh pull-out box 5 is fixedly connected to a slider 12. The inner walls of the front and rear sides of the box body 1 are fixedly connected to slide rails 11 that cooperate with the sliders 12.

[0023] The top plate 2 is connected to the box body 1 by a connecting assembly, which includes connecting blocks 8 fixedly connected to the left and right sides of the box body 1. Fixing blocks 7 are fixedly connected to both the left and right sides of the top plate 2. Bolts 9 are threadedly connected to the two fixing blocks 7 and the corresponding connecting blocks 8.

[0024] Among them, two strip plates 13 are fixedly connected to the inner walls of the left and right sides of the box body 1. Multiple guide rods 14 are fixedly connected to the adjacent sides of the two strip plates 13. The multiple guide rods 14 are all inclined. The multiple guide rods 14 on the left strip plate 13 are staggered with the multiple guide rods 14 on the right strip plate 13.

[0025] Two sealing plates 10 are rotatably connected to the inner right side of the box 1. When the mesh pull-out box 5 is fully pushed into the box 1, the sealing plate 10 is in a horizontal position above the mesh pull-out box 5. When the mesh pull-out box 5 is pulled out, the sealing plate 10 rotates downward under the action of gravity, closing the opening 4.

[0026] The functional principle of this utility model can be explained through the following operation: In the initial state, the top plate 2 is fixed to the box 1 with bolts 9, so that the ventilation mesh 3 covers the upper end of the box 1. At the same time, artificial feed and sawdust substrate are respectively laid in the two mesh pull-out boxes 5. Then, they are pushed into the box 1 along the slide rail 11, so that the mesh pull-out box 5 containing artificial feed is on top and the mesh pull-out box 5 containing sawdust substrate is on the bottom. At this time, the sealing plate 10 naturally fits against the inner wall of the right side of the box 1. When the parasitized egg mass is put in, the unparasitized host insects will be attracted by the feed and climb upward along the inclined and staggered guide rods 14 on both sides of the box 1, pass through the mesh of the mesh pull-out box 5 and enter the upper feeding area; while the parasitized host, due to the development regulation of the parasitized wasp, changes its behavior pattern and migrates downward to the lower sawdust substrate to cocoon and pupate, thereby achieving spatial isolation between the two. When it is necessary to change the feed or transfer the pupae and cocoons, pull the handle 6 to pull out the mesh pull box 5. The right-side sealing plate 10 will automatically rotate under the action of gravity to close the opening 4, preventing the escape of the non-parasitic host.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
