摘要: 【目的】研究溴氰虫酰胺对棉花蓟马的毒力和田间药效,为该药防治棉花蓟马提供依据。【方法】采用浸叶法,室内测定溴氰虫酰胺对棉花蓟马的毒力;评价溴氰虫酰胺对棉花的安全性;比较溴氰虫酰胺、呋虫胺、噻虫嗪3种药剂田间防治棉花蓟马的效果。【结果】溴氰虫酰胺对巨野、利津两地采集的棉花蓟马LC50分别为7.667 和17.049 mg/L,有较好的生物活性; 10%溴氰虫酰胺可分散油悬剂对棉花的安全阈值大于240 g.a.i./hm2(田间用量的4倍),对棉花安全性好;10%溴氰虫酰胺可分散油悬剂49.95、60 g.a.i./ hm2 2个处理,施药14 d后,巨野防效为91.11%、95.36%,利津防效为88.50%、97.32%。【结论】溴氰虫酰胺对棉花蓟马有较好的防效,生产中与其他作用类型杀虫剂交替使用,有效防控棉花蓟马的同时能一定程度上延缓棉花蓟马的抗药性。

Abstract: 【Objective】 The purpose of this study is to determine the toxicity and field efficacy of cyantraniliprole on cotton thrips and to provide the basis for the control of this insect.【Method】 The toxicity of cyantraniliprole to cotton thrips was determined indoors by leaf-leaching method, the cyantraniliprole safety to cotton was evaluated, and the effects of cyantraniliprole, dinotefuran and thiamethoxam were compared.【Result】 The results showed that thrips collected from Juye and Lijin showed good susceptibilities to cyantraniliprole, the LC50 were 7.667 mg/L and 17.049 mg/L. The safety threshold of 10% cyantraniliprole OD to cotton was higher than that of 240 g.a.i./hm2 (4 times of field dosage). After 14 days of application by 10% cyantraniliprole OD 7.667 mg/L and 17.049 mg/L, the control effects of Juye and Lijin were 91.11% and 95.36, 88.50% and 97.32%, respectively.【Conclusion】 Cyantraniliprole showed good control effects on cotton thrips, and alternate use of insecticides in production with other types of pesticides can effectively prevent and control cotton thrips while delaying the development of drug resistance to cotton thrips to a certain extent.

Key words: cotton thrips; cyantraniliprole; toxicity; control efficiency
