[0002] In agricultural production and daily life, the existence of pests poses a serious threat to crops, stored materials and human health and living environment. In order to effectively control pests, insecticides are widely used. Touch-kill type insecticides, as a common type of insecticide, act by directly contacting the body wall of pests to exert insecticidal effect.

[0003] The indoor biological determination of touch-kill type insecticides on insects usually requires the use of a spray tower to directly attach the pesticide to the surface of the insect body, and the pesticide can enter the insect body through the mouth or spiracle. The immersion method directly applies pesticide solution to the surface of the insect body by immersion, and determines the touch-kill toxicity of the insecticide penetrating the cuticle to cause insect poisoning and death.

[0004] The conventional indoor biological determination of touch-kill type insecticides on insects uses powder spraying and spraying devices, which not only requires the purchase of expensive equipment, but also has a high cost. The immersion method is time-consuming and labor-intensive, and also has the problem of inconsistent drug application time when repeating experiments. SUMMARY

[0008] Preferably, the height of the lower bottom is 10-15 mm, the diameter of the lower bottom is 40-60 mm, the height of the partition plate and the height of the liquid injection cylinder are the same as the height of the lower bottom, the diameter of the liquid injection cylinder is 8-10 mm, the included angle between every two adjacent partition plates is 60°-120°, the diameter of the distribution hole is 1-3 mm, the distribution holes are evenly distributed in the bottom of the liquid injection cylinder, and the number of distribution holes between every two adjacent partition plates is the same.

[0009] Preferably, the diameter of the filter screen is 42-62mm, the aperture of the filter screen is 2-4mm, the filter screen is selected according to the size of the insect to be tested, the thickness of the filter screen is 1-3mm, the edge of the filter screen is fixedly connected with a baffle, the height of the baffle is 1-2mm, and the thickness of the baffle is 1-2mm.

[0010] Preferably, the diameter of the upper cover is 40-60mm, and the height of the upper cover is 10-15mm.

[0011] The utility model has the following beneficial effects:

[0012] The device is divided into several chambers by the partition plate, can be used for repeated experiments, and the filter screen can be selected according to the size of different insects, so that the device has wide applicability. Compared with the traditional spraying method, the device does not need to purchase expensive instruments, has low cost and is easy to operate. Compared with the immersion method, the device saves time and labor, and different chambers are treated at the same time, so that the time error is reduced, the interference of other liquid medicine on the determination result is reduced, the accuracy of the determination result is improved, and the contact of personnel with the liquid medicine is greatly reduced, so that the device is safer.
