摘要: 【目的】研究十一星瓢虫取食氟啶虫酰胺、吡蚜酮、吡虫啉3种农药不同亚致死剂量处理棉蚜对其生长发育和繁殖的影响,为合理使用杀虫剂和协同生物防治防控棉蚜提供科学依据。【方法】根据3种不同农药对棉蚜的毒力测定结果,以供试药剂的LC25、LC50为处理浓度,采用浸叶法对棉蚜进行处理后,选取活体棉蚜作为十一星瓢虫的食物,分析对其生长发育和繁殖的影响。【结果】取食3种农药亚致死浓度处理的棉蚜,十一星瓢虫生长发育和繁殖均受到不同程度的影响。取食吡虫啉LC25和LC50处理的棉蚜,十一星瓢虫幼虫发育历期较对照分别延长3.01和4.57 d;取食吡蚜酮和氟啶虫酰胺LC25和LC50处理的棉蚜,其幼虫发育历期分别较对照延长0.09、0.50 d和1.48、1.64 d。取食吡虫啉LC25和LC50处理的棉蚜,十一星瓢虫产卵期明显缩短,分别较对照缩短2.56和3.46 d,其单雌产卵量分别较对照下降22.40%、32.45%,孵化率较对照分别下降9.57%、17.02%;十一星瓢虫取食氟啶虫酰胺和吡蚜酮亚致死剂量处理的棉蚜,其产卵量、卵孵化率等下降不明显。【结论】取食3种杀虫剂不同亚致死浓度处理后的棉蚜(害虫),对十一星瓢虫(天敌)的生长发育和繁殖均有不同程度的影响,其中吡虫啉较其他2种药剂影响更为明显,并且不同杀虫剂以及同一杀虫剂不同亚致死剂量对天敌的影响也有所不同。

Abstract: 【Objective】 This project aims to provide a scientific basis for the rational use of pesticides and the cooperative biological control of Aphis gossypii by studying the effects on development and fecundity of Coccinella undecimpunctata feeding on Aphis gossypii treated with sublethal doses of imidacloprid, pymetrozine and flonicamid.【Method】According to the results of toxicity determination of LC25 and LC50 of three insecticides on Aphis gossypii, the influence of growth, development and reproduction of Coccinella undecimpunctata feeding on Aphis gossypii treated with sublethal doses by the leaf soaking method were determined.【Result】Aphis gossypii treated with three different pesticides of LC25 and LC50 sublethal concentrations had different effects on the growth, development and reproduction of the Coccinella undecimpunctata. The larval developmental duration of Coccinella undecimpunctata feeding on Aphis gossypii treated with imidacloprid LC25 and LC50 were 3.01 d and 4.57 days longer than that of the control, respectively; After feeding on Aphis gossypii treated with pymetrozine and flonicamid of LC25 and LC50 concentrations, the developmental period of the larvae were prolonged by 0.09, 0.50, 1.48, and 1.64 days, respectively. The difference in fecundity parameters of aphids treated with pymetrozine and flonicamid sublethal doses were not significant, while the Aphis gossypii treated with imidacloprid LC25 and LC50 significantly shortened their spawning period, which were shorter 2.56 and 3.46 days than the control. The number of eggs laid per female decreased by 22.40%, 32.45% compared with the control, and the hatching rate decreased from 75.20% of the control to 68.00% and 62.40%.【Conclusion】Aphis gossypii (pests) treated with the three sublethal concentrations of the three insecticides had different effects on the growth, development and reproduction of the Coccinella undecimpunctata (natural enemy). Therefore, insecticides had certain effects on natural enemies, and the effects of different insecticides and different sublethal doses of the same insecticide on natural enemies were also different.
