摘要: 【目的】研究双酰胺类杀虫剂四唑虫酰胺对斜纹夜蛾的室内生测和田间药效试验。【方法】采用人工饲料混药法测定四唑虫酰胺对斜纹夜蛾3龄幼虫毒力,采用机率值分析方法对数据进行处理,用SAS统计分析系统计算毒力回归方程和LD50。用喷洒药剂悬浮液的方法进行田间试验,使用邓肯新复极差法(DMRT)对不同处理防治效果进行统计分析。【结果】四唑虫酰胺对斜纹夜蛾的LD50为0.58 μg/g,氯虫苯甲酰胺对斜纹夜蛾的LD50为1.12 μg/g,四唑虫酰胺的杀虫活性较高,但与氯虫苯甲酰胺的差异不显著。药后3 d,18%四唑虫酰胺悬浮剂7.5和10 mL/667m2处理对斜纹夜蛾的防效分别为85.00%和87.87%,显著高于5.0 mL/667m2 药剂处理,与5%氯虫苯甲酰胺悬浮剂 45 mL/667m2处理差异不显著。药后7 d,18%四唑虫酰胺悬浮剂 3个浓度处理对斜纹夜蛾的防效与5%氯虫苯甲酰胺 45 mL/667m2处理差异不显著。药后 14 d,18%四唑虫酰胺悬浮剂10 mL/667m2处理的防效显著高于5.0和7.5 mL/667m2药剂处理,但与5%氯虫苯甲酰胺 45 mL/667m2处理差异不显著。【结论】18%四唑虫酰胺悬浮剂对斜纹夜蛾具有良好的的防治效果,且随着浓度增高其防效增大。

Abstract: 【Objective】 Diamide insecticide is a new kind of insecticide which takes the receptor of fish nicotine as the target and has very high insecticidal activity to it. Chlorantraniliprole is the main variety of diamide insecticide. Due to the emergence of drug resistance, we have carried out the indoor bioassay and field efficacy test of a new kind of diamide insecticide tetraniliprole to S. litura. 【Methods】 The toxicity of tetraniliprole to the 3 rd instar larvae of S. litura was determined by the method of artificial feed mixture, the data were processed by the method of probability analysis, the regression equation and LD50 were calculated by SAS statistical analysis system, the field tests was carried out by spraying insecticide suspension, and the Duncan'smultiple range test (DMRT) was used to statistically analyze the effects of different treatments. 【Results】 The results of indoor bioassay experiment showed that the LD50 of tetraniliprole to S. litura was 0.58 μg/g, and the LD50 of chlorantraniliprole to S. litura was 1.12 μg/g. Tetraniliprole had higher insecticidal activity, but there was no significant difference between tetraniliprole and chlorantraniliprole. The results of field tests showed that 3 days after the treatment, the control effects of 18% tetraniliprole suspension 7.5 and 10 mL/ 667m2 on S. liturawas were 85.00% and 87.87%, respectively, which was significantly higher than that of 5.0 mL/ 667m2. However, the difference with 5% chlorantraniliprole 45 mL/667m2 was not significant. 7 days after the treatment, the control effect of three concentrations of 18% tetraniliprole suspension on S. litura was not significantly different with the 45 mL/667m2 of 5% chlorantraniliprole. On the 14 th day after the treatment, the control effect of 10 mL/667 m2 of 18% tetraniliprole suspension was significantly higher than that of 5.0 and 7.5 mL/667 m2, but there was no significant difference compared with 45 mL/667 m2 of 5% chlorantraniliprole. 【Conclusion】 The 18% tetraniliprole suspension had a good control effect on S. litura , and its control effect increases with increasing concentration. It has a good application prospect in the control of S. litura in cotton fields.
