5种杀虫剂对B型烟粉虱的毒力测定
Toxicities of five insecticides to Bemisia tabaci B-biotype
摘要
Abstract
Toxicities of raatrine, abamectin, cypermethrin, methomyl and imidacloprid to different development stages of Bemisia tabaci B-biotype were determined using leaf-dipping method. The results showed that matrine had the highest toxicity to eggs of B. tabaci, the LC50 value was 0.802 mg·L-1, which was 323.8 times as high as imidacloprid; abamectin, matrine and imidacloprid showed high toxicities to 1st and 3rd instar nymphs, and the toxicity to 1st instar nymphs was higher than to 3rd instar nymphs; abamectin and matrine had high toxicities to adults, which were 111.6 and 77.4 times as high as imidacloprid respectively; methomyl and cypermethrin had lower toxicities to all development stages of whitellies.关键词
