一、溴氰菊酯和杀虫脒混用 就北大生物系张宗炳教授对(虫非)蠊的中霉试验,溴氯菊酯和滴滴涕都是轴突神经毒剂,作用于轴状突上的神经冲动传导,使神经纤维产生一连串的神经连续冲动,引起昆虫体内酪氨酸脱羧酶活性增加,催化酪氨酸脱羧生成酪胺,酪胺对昆虫神经、血循环和消化系统的活动起抑制作用,最后导致昆虫死亡。但是昆虫的血淋巴中存在大量单胺氧化酶,极易催化酪胺氧化,去氨成为无神经毒性的对羟基扁桃酸,因此如溴氰菊酯使用浓度低,虫体内产生微量酪胺毒素只能引起暂时兴
First, the deltamethrin and chlordimeform mixed With the Department of Biology, Professor Zhang Zongbing Department of Biology, (non-cockroach) in the mold test, both permethrin and DDT are axonal nerve agents, acting on the axonal nerve impulses Conduction, nerve fibers produce a series of continuous nerve impulses, resulting in increased activity of tyrosine decarboxylase in insects, catalytic tyrosine decarboxylation of tyramine, tyramine on insect nerve, blood circulation and digestive system activity play a role in the final lead Insects die. However, there is a large amount of monoamine oxidase in hemolymph of insects, which can catalyze the oxidation of tyramine and detoxification to become nontoxic parahydroxy mandelic acid. Therefore, if the concentration of deltamethrin is low, trace amounts of tyramine toxin can only cause temporary Hing
