抗蜕皮激素“灭幼脲1号”(又名除虫脲)是一种昆虫发育抑制剂,它对昆虫具有独特的杀伤机理,故称为第三代杀虫剂。它的作用主要是,通过幼虫和成虫口服后抑制体内蜕皮激素,使真皮细胞几丁质合成酶产生受阻,新内表皮几丁蛋白复合物不能正常形成,旧表皮脱除受阻而僵化,所以它只能作用于节肢动物所特有的蜕皮与变态过程,因而对哺乳类和其他生物毒害很小,不污染环境。近几年来国内外用该激素对许多农林害虫进行活性测定及应用试验,表明其对鳞翅目中具有明显
Anti-ecdysone “Diurea 1” (also known as diflubenzuron) is a kind of insect development inhibitor, which has a unique mechanism of killing insects, it is called the third generation of insecticides. Its main role is that, after larvae and adults oral administration of ecdysterone suppression, so that the dermis of chitin synthase obstruction, the new inner epidermis chitin complex can not be formed normally, blocked the removal of the old epidermis and rigid, so it It can only act on the molting and metamorphosis peculiar to arthropods, so it has little toxicity on mammals and other organisms and does not pollute the environment. In recent years, the hormones at home and abroad with many of the determination of agricultural and forestry pests and application tests showed that it has obvious Lepidoptera
