摘要: 目的】研究四氯虫酰胺对棉铃虫生物活性的温度效应及其影响程度,分析棉铃虫体内4种解毒酶系对该温度效应的影响机制。【方法】采用浸叶法,分别测定15、20、25、30和35℃条件下,四氯虫酰胺对棉铃虫的室内生物活性,测定四氯虫酰胺亚致死剂量下,棉铃虫体内羧酸酯酶(CarE)、谷胱甘肽S-转移酶(GST)、多功能氧化酶(MFO)和尿苷二磷酸糖基转移酶(UGT)比活力的变化。【结果】四氯虫酰胺对棉铃虫的生物活性具有明显的正温度效应,与15℃时相比,其温度系数从+5.52增长为+1 257.35。四氯虫酰胺对棉铃虫的正温度效应可能与GST和MFO有关,其中GST在较低温下的活性变化尤为显著,而CarE和UGT则未发现与四氯虫酰胺生物活性的正温度效应明显相关。【结论】四氯虫酰胺对棉铃虫表现为明显的正温度系数药剂,高温时使用生物活性最佳,低温时抑制GST活性,可能会提高四氯虫酰胺对棉铃虫的生物活性。

Abstract: Objective】 To clarify the temperature effect and its degree on the biological activity of tetrachlorantraniliprole to Helicoverpa armigera, and to explore the influence mechanism of four detoxification enzymes of H. armigera to this temperature effect.【Methods】 The authors respectively determined the indoor biological activities of tetrachlorantraniliprole to H.armigera at 15, 20, 25, 30 and 35℃ with the leaf dipping method, and then determined the specific activities of carboxyl esterase (CarE), glutathione S-transferase (GST), multifunctional oxidase (MFO) and UDP-glycosyltransferase (UGT) of H.armigera treated by the sublethal doses of tetrachlorantraniliprole.【Results】 Tetrachlorantraniliprole had a significant positive temperature effect on the biological activity to H.armigera. Compared with 15℃, the temperature coefficient increased from +5.52 to +1,257.35. From the study about the mechanism of the four detoxification enzymes of H.armigera to the temperature effect, it was found that the positive temperature effect might be related to GST and MFO. Among them, the activity of GST at lower temperatures changed more significantly, while CarE and UGT were not clearly related to the positive temperature effect on the biological activity of tetrachlorantraniliprole. 【Conclusion】 Tetrachlorantraniliprole was an insecticide with an obviously positive temperature coefficient to H. armigera and the biological activity would be best when used at high temperature. The biological activity of tetrachlorantraniliprole against H. armiger may increase when the activity of GST is inhibited at low temperature.
