为了解微生物农药的安全性，通过对苏云金杆菌、增产菌、白僵菌、棉铃虫核型多角体病毒、茶小卷叶娥颗粒体病毒、苜蓿银纹夜蛾颗粒体病毒５ 种微生物农药的安全性评价，认为单纯微生物农药没有化学农药意义上的急、慢性毒性，所试微生物对哺乳动物不致病，无生殖毒性和致突变作用，是安全的。所试微生物农药之所以对哺乳动物无危害，关键可能是从植物、昆虫分离的这些细菌、真菌、杆状病毒不能侵入动物机体，在体内不能复制、繁殖
In order to understand the safety of microbial pesticides, five kinds of microbial pesticides such as Bacillus thuringiensis, growth bacteria, Beauveria bassiana, Helicoverpa armigera nucleopolyhedrovirus, Chamaecrista parvovirus, Autographa californica granulosis virus Safety evaluation, that the simple microbial pesticides in the sense of acute and chronic chemical pesticides in the sense that the tested microorganisms on mammals disease-free, non-reproductive toxicity and mutagenicity, is safe. The reason why the tested microbial pesticides are not harmful to mammals is that these bacteria, fungi and baculovirus isolated from plants and insects may not be able to invade into the animal body and can not be reproduced and multiplied in vivo
