烯啶虫胺、醚菊酯及其混剂对褐飞虱的毒力测定
Toxicity of nitenpyram, ethofenprox and their mixtures on Nilaparvata lugens
摘要
Abstract
[ObjectiveJThe present experiment was conducted to study the toxic effects of nitenpyram, ethofenprox and their mixtures on Nilapanata lugens, and to provide scientific basis for developing chemical pesticide for its control. [Method] The toxic effects of nitenpyram, ethofenprox and their mixtures on N. lugens were determined by using rice stem dipping method. [Result]The values of LC30 for nitenpyram, etofenprox on the 3nd nymph of Nilapanata lugens were recorded as 0.4922 and 9.1847 mg a·i·L-1, respectively. When the efficiency mass ratio of the two single insecticides was 1:12 and 1:27 (Nitenpyram:Etofenprox), the co-toxicity coefficients (CTC) were 249.89 and 138.15, respectively. [Conclusion JThe data revealed that combined mixture of two insecticides in the ratioes of 1:12 and 1:27 (Nitenpyram:Etofenprox) gave excellent synergistic effect.关键词
