Azadirachtin is a biological insecticide extracted from neem tree species. It can control more than 200 agricultural, forest, storage and indoor health pests. It is recognized as a broad-spectrum, efficient, low toxicity, easy to degrade, residue free insecticide and has no drug resistance in the world. It can drive and kill almost all plant pests, indoor bedbugs, fleas, flies and mosquitoes. Especially for Hemiptera, Lepidoptera, Coleoptera and other pests, without any pollution to humans, animals and the surrounding environment. Azadirachtin compounds are very similar to steroids, steroids and other hormone substances in insects, so it is difficult for pests to distinguish whether they are inherent in the body or imposed by the outside world. Therefore, they can not only enter the body of pests and interfere with a life process of pests, so as to kill pests, but also not easily cause pests to develop drug resistance. These compounds are very different from vertebrate hormones, so they are almost harmless to human and animal. Azadirachtin has antibacterial and antifungal activities. It can be used to control or drive away flies, mosquitoes, locusts and other pests indoors, in vegetable gardens, gardens and lawns, as well as ticks, flies, flies, flies, midges, bedbugs, fleas and mosquitoes on pets, cattle, sheep and other livestock. The generally accepted mechanism of azadirachtin on insects is as follows: it produces antifeedant effect directly or indirectly by destroying the chemical sensing organs of insect mouthparts; Through the action of digestive enzymes in the midgut, the nutrient conversion of food is insufficient, which affects the vitality of insects. High dose Azadirachtin can directly kill bedbugs, fleas and other insects, while low dose will lead to permanent larvae, or deformed pupae and adults.
Azadirachtin can reduce the number of blood cells of insects, reduce the protein content in hemolymph, reduce the concentration of trehalose and metal cations in hemolymph, inhibit the activities of protease, amylase, lipase, phosphatase and glucoamylase in insect midgut esterase and fat body, reduce the feeding rate and food conversion and utilization rate of insects, and affect the normal respiratory rhythm of insects. Reduce the content of DNA and RNA in insect fat body, reduce the content of protein, glycogen and lipid in female ovary, fallopian tube and seminal vesicle and the activity of some enzymes, affect the male reproductive system, make the brain, pharyngeal body, cardiac body, pre thymus and fat body of insects sick, affect the hormone balance in insects, and interfere with the growth and development of insects.
