摘要: 目的】评价氟啶虫胺腈、氟吡呋喃酮、烯啶虫胺原药以及22%氟啶虫胺腈悬浮剂、17%氟吡呋喃酮可溶液剂和5%烯啶虫胺水剂不同处理剂量对棉蚜的杀虫活性。【方法】采用浸叶法和茎叶喷雾法进行室内毒力测定和田间药效试验。【结果】氟啶虫胺腈/氟吡呋喃酮、烯啶虫胺原药对棉蚜24 h LC50分别为2.41、1.49、0.81 μg/mL;48 h LC50分别为1.35、0.72、0.32 μg/mL。22%氟啶虫胺腈悬浮剂和7%氟吡呋喃酮可溶液剂对棉蚜具有很好的速效性,平均防治效果在70%以上。【结论】3种药剂均表现很好的持效性,氟啶虫胺腈、氟吡呋喃酮、烯啶虫胺可有效防治棉蚜,是棉花生产上防治棉蚜的高毒农药理想的替代药剂。

Abstract: Objective】 To evaluate the insecticidal activity of chlorfenapyr, flupirfuranone, nitenpyram, 22% flupirfenapyr SC, 17% flupirfuranone SC and 5% nitenpyram against cotton Aphis gossypii by indoor toxicity test and field efficacy test. 【Methods】 indoor toxicity test and field efficacy test were conducted by leaf dipping method and stem leaf spray method respectively. 【Results】 The results of indoor toxicity test showed that the 24 h LC50 of fipronil flupyrfuranone and nitenpyram to Aphis gossypii were 2.41, 1.49 and 0.81 μg/mL respectively, and the 48 h LC50 were 1.35, 0.72 and 0.32 μg/mL respectively. The results of field trials showed that 22% fipronil SC and 7% flupyrfuranone SC had good quick effect on Aphis gossypii, and the average control effect was more than 70%. 【Conclusion】 Fipronil, flupyrfuranone and nitenpyram can effectively control Aphis gossypii, and they are ideal substitutes for high toxic pesticides to control Aphis gossypii in cotton production.

Key words: fipronil; flupyrfuranone; nitenpyram; insecticide; Changji area of Xinjiang; Aphis gossypii; indoor toxicity test; field efficacy
