[0026] In this embodiment, the box body 1 , the box body 2 4 , and the cover are all made of transparent plastic products, and the cover is elastic and can be stably buckled on the box body 1 .

[0027] When in use, put the wheat moth wasp and host A into box body 1 and close the lid. The air vents 3 on the lid can let air into box body 1 to ensure that the wheat moth wasp and host A get oxygen. Put host B into box body 2 4. The provided connecting parts facilitate the disassembly of box body 2 4 and box body 1, and then facilitate the replacement of different types of host B in box body 2 4. The provided blocking nets 1 9 and 10 can be used to dissipate the odor of box body 2 4 into box body 1, and at the same time prevent the ovipositor of wheat moth wasp from extending into box body 2 4 and injecting venom into host B to paralyze and lay eggs.

[0028] The utility model is easy to operate and saves time and effort.

[0029] Furthermore, in order to facilitate the detachable connection between box body 1 and box body 2 4 and prevent the meal moth cocoon wasp from laying eggs and parasitizing host B, the connecting piece includes a tube body 6 fixedly connected to the bottom end of box body 1, the bottom end of the outer wall of tube body 6 is fixedly provided with an external thread 7, and the top end of the inner wall of box body 2 4 is fixedly provided with an internal thread 8.

[0030] Furthermore, to prevent the meal moth wasp from entering the box body 2 4 and the host B from entering the box body 1 , the mesh numbers of the blocking net 1 9 and the blocking net 2 10 are both 200-270 meshes. In the present embodiment, the blocking net 1 9 and the blocking net 2 10 both use 200-mesh gauze.

[0031] Furthermore, in order to facilitate the taking and placing of the meal moth cocoon wasp and host A, as well as the supply of nutrition to host A, the lid includes a cover body 2, the cover body 2 is an elastic body, and a groove 5 is opened in the middle of the bottom end of the cover body 2.

The air vents 3 provided on the lid can allow air to enter the box body 1 to ensure that the wheat moth wasp and host A obtain oxygen. Host B is placed in the box body 2 4. The provided connecting piece facilitates the disassembly of the box body 2 4 and the box body 1, and further facilitates the replacement of different types of host B in the box body 2 4. The provided blocking nets 1 9 and 10 can be used to disseminate the odor of the box body 2 4 into the box body 1, while preventing the ovipositor of the wheat moth wasp from extending into the box body 2 4 and injecting venom into the host B to paralyze and lay eggs. By changing the different types and categories of host B in the box body 2 4, the effects of different odors emitted from the box body 2 4 on the secretion of venom by the wheat moth wasp are studied, and the paralysis rate of the wheat moth wasp on the host A is counted. It should be noted that, according to the experimental requirements, the host B can be an insect or a plant. The experimental duration is generally 24 hours, which can be specifically selected according to the actual experimental requirements.
