摘要
[目的】研究氯氟氰虫酰胺对棉铃虫的毒力和田间药效。【方法】采用浸渍法，测定氯氟氰虫酰胺对棉铃虫的室内活性，并进行田间药效试验。【结果】氯氟氰虫酰胺对棉铃虫的毒力Lc，值为0．145mg／L，与氟苯虫酰胺、氯虫苯甲酰胺相当，高于高效氯氰菊酯。田间试验结果表明，药后3～10d，在45～60ga．i．／hm2时，20％氯氟氰虫酰胺悬浮剂对棉铃虫的杀虫、保蕾和保顶防效均可达90％以上，与氟苯虫酰胺、氯虫苯甲酰胺相当，高于高效氯氰菊酯。【结论】氯氟氰虫酰胺对棉铃虫具有良好的室内生物活性和田间防效，可应用于防治棉铃虫。
[Aims] The aim of this study is to evaluate the toxicity and the field efficacy of cyhalodiamide against Helicoverpa armigera. [Methods] The toxicity of cyhalodiamide against H. armigera was tested by leaf-dipping method, and field trial was carried out. [Results] The LCs0 value of toxicity against H. armigera was 0.145 mg/L, almost equivalent to that of flubendiamide and chlorantraniliprole, higher than that of beta cypermethrin. The control efficacy against H. armigera 3-10 d after treatment was above 90% at 45-60 g a.i./ha, equivalent to that of flubendiamide and chlorantraniliprole, higher than that of beta cypermcthrin. [Conclusions] Cyhalodiamide has good bioactivity and field efficacy against H. armigera, and can be sprayed to control H. armigera.
