摘要
采用浸渍法测定了3种农药制剂阿维.苏云菌WP、氰戊.马拉松EC和吡虫啉WP对桃蚜的室内毒力。结果表明,20%氰戊.马拉松EC的毒力最强,LC50为0.792 5 mg/L;10%吡虫啉WP的毒力次之,LC50为10.008 1 mg/L;0.1%阿维.苏云菌WP的毒力最差,LC50为279.405 8 mg/L。
The laboratory toxicity of three pesticide formulations to Myzs persicae was determined with leaf dips method. The results showed that the toxicity of Fenvalerate · malathion EC (20 % ) is the strongest (the LCs0 is 0.792 5 mg/L), then followed by fenvalerate ·malathion EC( 10% ) is imidacloprid WP (the LC50 is 10.008 1 rag/L) and abamectin ·Bt WP(0.1% )( the LC50 is 279.405 8 mg/L).
