湖北省农科院植保土肥研究所近期通过叶片浸渍法研究了氟啶虫胺腈对棉蚜的室内活性,同时分析了其对棉花的安全性。室内毒力测定结果表明,氟啶虫胺腈处理棉蚜24小时的LC50和LC90为1.98mg/L和26.02mg/L,显著低于吡虫啉的8.69mg/L和132.68mg/L,毒效比达4.39;处理48小时后,氟啶虫胺腈对棉蚜仍表现出很高的杀虫活性,且显著高于吡虫啉。棉花安全性试 Hubei Academy of Agricultural Sciences Institute of Plant Protection Soil and Fertilizer recently by leaf dipping method of flurbaron nitrile to cotton aphid indoor activity at the same time analyzed its security to cotton. The results of indoor toxicity test showed that the LC50 and LC90 of chlorfenapyr for 24 hours were 1.98mg / L and 26.02mg / L, significantly lower than that of imidacloprid 8.69mg / L and 132.68mg / L, respectively Up to 4.39. After 48 hours of treatment, the nitrendipamide showed high insecticidal activity against cotton aphid and was significantly higher than imidacloprid. Cotton safety test
