苏芸金杆菌作为微生物农药,已在国内外广泛生产应用。但在生产中往往受到噬菌体的侵染,严重地影响这种微生物农药的应用和发展。蜡螟杆菌“010”(简称“010”)是我组于1964年自蜜蜂死亡幼虫体内分离出的一种对人畜无害的中温好气性芽孢杆菌。北京动物研究所(1973)鉴定为苏芸金杆菌蜡螟变种(Bacillus thuringiensis var.galleriae)。它对多种鳞翅目害虫有高效的毒杀作用,田间防治菜青虫(Pieris rapae)、稻苞虫(Parnara guttata)、松毛虫(Dendrolimus punctatus)、稻纵卷叶螟(Cnaphalocrocis medinalis)、杨天社蛾(Melalopha(Pygaera)anachoreta)等试验效果显著。死亡率一般都在90—95％,个 Bacillus thuringiensis as a microbial pesticide, has been widely produced at home and abroad. But in the production are often infected by phages, which seriously affect the application and development of this kind of microbial pesticide. Bacillus callosus “010” (referred to as “010”) is my group in 1964 from dead bee larvae isolated a kind of harmless to humans and animals in the temperature of aerobic Bacillus. The Beijing Institute of Zoology (1973) identified as Bacillus thuringiensis var.galleriae. It is highly toxic to many lepidopteran pests, and the field control Pieris rapae, Parnara guttata, Dendrolimus punctatus, Cnaphalocrocis medinalis, Moth (Melalopha (Pygaera) anachoreta) and other test results were significant. Mortality rates are generally 90-95%, a
