摘  要:
参照NY/T 3152—2017《微生物农药环境风险评价试验准则》测定了0.2亿孢子/mL蝗虫微孢子虫悬浮剂对日本鹌鹑、意大利蜜蜂、家蚕、大型溞和斑马鱼等环境非靶标生物的毒性。结果表明,在供试的最大危害暴露剂量下,0.2亿孢子/mL蝗虫微孢子虫悬浮剂对蜜蜂经口毒性的致死率为8.3%,但与对照组无显著差异;日本鹌鹑、意大利蜜蜂、家蚕、大型溞和斑马鱼与其接触均未出现死亡。上述结果表明0.2亿孢子/mL蝗虫微孢子虫悬浮剂对主要的环境非靶标有益生物较安全。

摘  要:
The toxicity of 20 million spores/mL Nosema locustae SC to some environmental non-target organisms such as Coturnix japonica, Apis mellifera, Bombyx mori, Daphnia magna, Brachydanio rerio were determined according to NY/T 3152-2017 "Environmental Risk Assessment Test Guidelines for Microbial Pesticides". The results showed that the lethal rate of 20 million spores/mL Nosema locustae SC to honeybee oral toxicity was 8. 3 % at the maximum exposure dose tested, but there was no significant difference with the control group. No death occurred in Coturnix japonica, Bombyx mori, Daphnia magna, Brachydanio rerio, and Apis mellifera contact toxicity. The above results showed that Nosema locustae was relatively safe for major environmental non-target beneficial organisms.
