福建农林大学植物保护学院研究人员近期采用浸叶法,分别测定了苦参碱、阿维菌素、氯氰菊酯、灭多威和吡虫啉等5种杀虫剂对B型烟粉虱不同虫态的毒力。试验结果表明,苦参碱对烟粉虱卵的毒力最高,LC50值为0.802毫克/升,其毒力是吡虫啉的323.8倍;阿维菌素、苦参碱和吡虫啉对烟粉虱1龄和3龄若虫的毒力均较高,但对1龄若虫的毒力高于3龄若虫;阿维菌素和苦参碱对烟粉虱成
Institute of Plant Protection, Fujian Agriculture and Forestry University recently adopted the dipping leaf method were measured five kinds of matrine, abamectin, cypermethrin, methomyl and imidacloprid and other insecticides on the Bemisia tabaci B force. The results showed that matrine had the highest virulence to B. tabaci eggs with an LC50 value of 0.802 mg / l, and its virulence was 323.8 times that of imidacloprid. Abamectin, matrine and imidacloprid had no significant effect on the first- And 3rd instar nymphs were higher, but the virulence of 1st instar nymphs was higher than that of 3rd instar nymphs. Avermectin and matrine had stronger toxicity to Bemisia tabaci
