摘要: 目的 研究氟啶虫胺腈对南疆棉田三种蚜虫的毒力及其对三种瓢虫的安全性。方法 以22%氟啶虫胺腈悬浮剂和5%吡虫啉乳油为供试药剂,室内通过药膜法测定棉蚜、棉黑蚜和棉长管蚜氟啶虫胺腈的敏感性,采用滤纸接触法测定两种药剂对十一星瓢虫、异色瓢虫和龟纹瓢虫的安全影响。结果 棉蚜、棉黑蚜和棉长管蚜对两种药剂表现出不同的敏感性,三种蚜虫3日龄若蚜和成蚜对氟啶虫胺腈敏感性均高于吡虫啉,棉蚜3日龄若蚜和成蚜对氟啶虫胺腈的LC50分别为1.17、0.36 mg/L,5%吡虫啉乳油和22%氟啶虫胺腈悬浮剂的相对毒力分别为55.41、60.11,棉蚜对5%吡虫啉乳油表现出较强的耐药性。22%氟啶虫胺腈悬浮剂对十一星瓢虫、异色瓢虫和龟纹瓢虫的毒力均小于5%吡虫啉乳油,22%氟啶虫胺腈悬浮剂对三种瓢虫成虫的安全系数分别是5%吡虫啉乳油的6.16、7.90和4.54倍,对3龄幼虫的安全系数分别是5%吡虫啉乳油的5.07、7.48和9.23倍。结论 22%氟啶虫胺腈悬浮剂可用来防治棉田棉蚜、棉黑蚜和棉长管蚜,且对棉田瓢虫有较高的安全性。

Abstract: Objective To clarify the toxicity of sulfoxaflor to three aphids in cotton fields of Southern Xinjiang and its safety to three predatory natural enemies.Method The susceptibilities of Aphis gossypii, Aphis atrata, Acyrthosiphom gossypii were determined by membrane methods in the laboratory with 22% fludinamidonitrile suspension agent and 5% imidacloprid as the test reagent, and the safety of Coccinella undecimpunctata, Harmonia axyridis, Propylaea japonica was determined by filter paper contact methods. Result The results showed that A. gossypii, A. atrata, Ac. gossypii showed different susceptibilities to two kinds of insecticides. The susceptibilities of 3-day-old larvae and adult aphids of three kinds of aphids to sulfoxaflor were significantly higher than that of imidacloprid. The LC50 of 3-day-old larvae and adults of cotton aphids to sulfoxaflor were 1.17 mg/L and 0.36 mg/L, its' indexes of relative toxicity (5% imidacloprid EC/22% sulfoxaflor SC) were 55.41 and 60.11, and cotton aphids showed strong resistance to 5% imidacloprid EC. The toxicities of 22% sulfoxaflor SC to three predatory ladybugs were lower than those of 5% imidacloprid EC, and the safety coefficients of 22% sulfoxaflor SC to ladybug adults and3-instar larvae were 6.16, 7.90, 4.54 and 5.07, 7.48 and 9.23 times higher than that of 5% imidacloprid EC, respectively. Conclusion 22% sulfoxaflor can be used to control the three kinds of aphids, and had high safety to natural enemies.
