Technical Field

[0001] The utility model belongs to the field of pesticide toxicity testing, and in particular relates to a pesticide toxicity testing device. Background Art

[0002] Drug toxicology is a science that uses the principles and methods of toxicology to conduct a comprehensive and systematic safety evaluation of drugs based on their physical and chemical properties, and to clarify their toxic mechanisms in order to reduce the degree of harm to human health caused by drugs; its main purpose is to guide the rational use of drugs in clinical practice, reduce adverse drug reactions, and reduce the failure of new drug development due to drug toxicity. In the field of plant protection, drug toxicity testing is a basic experiment that reveals the toxicity level of drugs to organisms. Even if you want to find a new pesticide, it is necessary to study the degree of toxicity to insects to understand whether the drug can effectively kill the target insects.

[0003] When testing drugs on whiteflies, the existing insect test box cannot clearly observe whiteflies, and because whiteflies are small and fast, it is difficult to quickly keep the whiteflies in the insect test box in a static state, which is not convenient for counting and checking the released whiteflies and understanding their mortality rate after the test, affecting the progress of the test. Therefore, we proposed an insecticide toxicity test device. Utility Model Content
