1.微生物杀虫剂——青虫菌一种流行性细菌杀虫剂,由苏云金杆菌蜡螟变种发酵、加工而成的制剂。昆虫食入后很快停止进食。芽孢在虫体内发芽,进入体腔,利用昆虫体液大量繁殖,使昆虫得败血症而死。病虫粪便和死虫再传染其他害虫,引起流行病,从而达到控制害虫的目的。青虫菌杀虫起效慢,施药后2~3天见效,有时要4~5天。因是活芽孢起杀虫作用,故药效受环境影响大。对家蚕有毒,对人、家畜、蜜蜂和植物无毒,不污染环境。每公顷用100亿个/克的菌粉750~1500 1. Microbial Pesticide - Coccidiosis An epidemic bacterial insecticide, Bacillus thuringiensis wax borer variant fermentation, processed from the preparation. Insects quickly stop eating after eating. Spores germinate in the worms, into the body cavity, the use of insect body fluids multiply, so that insects have sepsis and die. Pest excrement and dead insects re-infection of other pests, causing epidemics, so as to achieve the purpose of pest control. Caterpillar fungus insecticidal slow onset, 2 to 3 days after application effective, and sometimes to 4 to 5 days. Because living spores play a pesticidal effect, so the efficacy of the environment by the big impact. Toxic to silkworms, non-toxic to humans, livestock, bees and plants, does not pollute the environment. With 100 million per hectare / g of powder 750 ~ 1500
