摘要: 【目的】研究5种双酰胺类杀虫剂对甜菜夜蛾毒力的温度效应和变化趋势,为不同环境温度下甜菜夜蛾的化学防控提供依据,为有效的提高双酰胺类杀虫剂的利用率奠定理论基础。【方法】采用浸叶法测定5种双酰胺类杀虫剂在15~35℃对甜菜夜蛾3龄幼虫的室内毒力。【结果】在供试温度范围内,5种双酰胺类杀虫剂对甜菜夜蛾的毒力均呈正温度效应。氯虫苯甲酰胺、氟苯虫酰胺对甜菜夜蛾毒力分别增长了6 527.23和3 939.80倍,溴氰虫酰胺和氟氰虫酰胺温度系数稍低于前两者,分别为+407.24和+566.98,四氯虫酰胺温度系数最小,仅为+142.05。从各供试药剂温度系数变化趋势来看,除四氯虫酰胺温度系数增长趋势一直较为平缓外,其他4种供试药剂均在不同温度梯度下出现了明显的温度系数增长。【结论】在15~35℃范围内,5种双酰胺类杀虫剂对甜菜夜蛾的毒力均表现出极明显的正温度效应。

Abstract: 【Objective】 To clarify the temperature effects and their variation trend on the toxicity of five diamide Insecticides to Spodoptera exigua.【Methods】 In this paper, the laboratory toxicity of five diamide insecticides to the 3 rd instar larvae of S. exigua in the range of 15-35℃ was determined by leaf dipping method.【Results】 Within the tested temperature range, the temperature effects on the toxicity of the five diamide insecticides to S. exigua all showed positive. The toxicity of chlorantraniliprole and flubendiamide to S. exigua increased by 6,527. 23 and 3,939.80 times, respectively. The temperature coefficients of cyantraniliprole and tetraniliprole increased to +407.24 and +566.98, respectively, which were slightly lower than those of chlorantraniliprole and flubendiamide. And SYP-9080 has the lowest temperature coefficient, only +142.05. According to the variation trend of the temperature coefficient of these insecticides, except for the temperature coefficient of SYP-9080 has been increased slowly, the other four test insecticides showed significant temperature coefficient increasing trend under different temperature gradients.【Conclusion】 The toxicity of the five diamide insecticides to S. exigua showed a very significant positive temperature effect in the range of 15 to 35℃. This study will provide the basis for chemical control of S. exigua at different environmental temperatures, and will also lay a theoretical foundation for improving the utilization of diamide insecticides effectively.
