苏云金芽胞杆菌安全性的研究进展

Research Progress on the Safety of Bacillus thuringiensis

苏云金芽胞杆菌(Bacillus thuringiensis,简称Bt)是目前应用最为广泛的一类微生物农药。本文分析比较了我国及美国Bt产品登记和安全评价等情况,并对Bt制剂的风险评价进行了分析。Bt菌株不是人或其他哺乳动物的已知病原体,对哺乳动物无毒性、感染性和致病性;其种群数量在环境中呈逐渐减少趋势,无残留风险;对非靶标昆虫的生存和繁殖及土壤微生物群落结构无显著影响。

Bacillus thuringiensis(Bt)has become the most widely used type of microbial pesticide.This review summarized the registration and safety evaluation of Bt products in China and the United States,and analyzed the risk evaluation of Bt products.Bt strains are not known pathogens of humans or other mammals,and non-toxic,infectious and pathogenic to mammals,poultry,etc.;their populations gradually decreased in the environment,and there is no residual risk;it has no significant impact on the survival and reproduction of non-target insects and the structure of soil microbial community.
