METHOPRENE 40596-69-8 Large in promotion

Details:

Insect juvenile hormone Methoprene is a kind of insect Juvenile hormone type biochemical insecticide developed by Novartis Co., Ltd. The juvenile hormone is capable of regulating the growth and development of insects and hormones themselves. The major role of juvenile hormone is to suppress the un-aged larvae metamorphosis, to maintain the larvae characteristics of juvenile insects, so that the larvae stage is still maintained after molting.
The methoprene act as a kind of tobacco leaf protectors and interfere with the peeling process of insects. It can interfere with the growth and development process of tobacco beetle and tobacco moth so that the imago would lose reproductive capacity, further effectively controlling the growth of the population of the tobacco leaf pest.
Information regarding the toxicity, application, and precautions of the insect-preserving hormone insecticides are edited by Tongtong from Chemicalbook (2017-03-04).
Toxicity Acute oral LD50> 34 600mg/kg: body weight.
The preparation has a stimulating effect on the eyes, belonging to a low-toxicity pesticide.
Application Juvenile hormone can not kill insects directly insects, can only make insects died in the metamorphosis process, or through infertility or eggs do not hatch to reduce the number of offspring population, it is slow, can not quickly control the risk of fulminant pests, Agricultural applications. At present mainly used in the following areas:
Control of health pests. Ethylenolate has a high activity of German cockroaches, which makes both female and male adults sterile. Continue to use this drug treatment, six months to a year later, it can be inferred because of infertility, large cockroaches are also effective. It is also effective to control the fleas, mosquitoes and flies.
Control of Hemiptera pests. Enzyme is effective in the control of greenhouse aphids and whitefly. But in the field application stability is not good. The control of greenhouse whitefly and scale insects is effective.
Control pests. Proposed juvenile hormones have high activity against Lepidoptera pests during storage of cereals, flour, tobacco and so on. The United States tries to use insecticides and dioxins to be effective for many pests.
Control of ants. The insect insect bait can block the normal larvae of the larvae, so that the king of infertility, prevention and treatment of kitchen ants and other effective. It is also useful to report juvenile hormone treatment of termites.
Pollution-free new pesticides for the control of tobacco storage pests and beetles and other beetles.
Increased silk production. (5 to 4 μg/head) or 5-year-old silkworm (1 to 3 μg/head) can inhibit metamorphosis, so that the fifth instar larvae extended More than 1 day, food intake increases, individual increases, silking increases. Generally can make the amount of cocoon silk increased by about 15%.Insects are different from other insecticides, and they can control pests that are resistant to other insecticides. However, attention should also be paid to the emergence and development of drug resistance to juvenile hormones.
