摘　　要：【目的】研究新疆伊犁河谷玉米高效杀虫剂混配种类、施药量和减药增效配套技术,为新疆玉米主要害虫的协同高效防治及节本增效提供指导。【方法】选用植保无人机喷施不同杀虫剂,同时配合增效助剂对药剂混配组合进行减施处理,比较分析其对亚洲玉米螟、双斑萤叶甲和棉铃虫的实际防效。【结果】不同复配药剂对亚洲玉米螟、双斑萤叶甲、棉铃虫的防治效果不同,处理30%氯虫苯甲酰胺SC+9.8%甲维·虱螨脲SC药剂对玉米主要害虫的防效优于处理30%氯虫苯甲酰胺SC+22%噻虫·高氯氟SC。其中处理530%氯虫苯甲酰胺(凯荔)SC 7.5 mL/667m^(2)+9.8%甲维·虱螨脲(丝扑瑞)SC 18.75 mL/667m^(2)+迈诺安飞防助剂10 mL/667m^(2)药后28 d,对亚洲玉米螟、双斑长跗萤叶甲、棉铃虫防效最高,防效分别为91.68%、93.44%和91.22%。相同复配药剂下,添加飞防助剂可在降低用药量的同时增加其防治效果。【结论】处理5防效最佳,于玉米大喇叭口期施药,可兼防多种玉米害虫。此外,飞防过程中适量添加飞防助剂可达到较好的减药增施效果。【Objective】The screening of mixed types and application amounts of high-efficiency insecticides for maize in the Ili River Valley,and the research on the matching technology of reducing and increasing efficiency were carried out to provide guidance for the coordinated and efficient control of major pests of maize in Xinjiang and cost-saving and efficiency-increasing.【Methods】By using plant protection drones to spray pesticides with different insecticidal mechanisms,and at the same time with synergistic additives to reduce the application of the mixed combination of pesticides,the actual control effects on Ostrinia furnacalis,Monolepta hieroglyphica and Helicoverpa armigera were compared and analyzed.【Results】The results showed that the control effects of different compound insecticides on Ostrinia furnacalis,Monolepta hieroglyphica and Helicoverpa armigera were different.The control effect of 30%chlorantraniliprole+9.8%emamectin benzoate·lufenuron on the main pests of maize was better than that of 30%chlorantraniliprole+22%thiamethoxam·high chlorine fluoride.The best pesticide and dosage for the control of pests by drone application were as follows:30%chlorantraniliprole SC 7.5 mL/667m^(2)+9.8%emamectin benzoate·lufenuron(Sipurui)SC 18.75mL/667m^(2)+10 mL/667m^(2).After 28 days of treatment,the control effects on Ostrinia furnacalis,Monolepta hieroglyphica and Helicoverpa armigera were the highest,and the control effects were 91.68%,93.44%and 91.22%,respectively.Under the same formula of compound agents,the addition of flight prevention additives can reduce the dosage and increase the control effect.【Conclusion】Treatment 5 is the best.Pesticide application at the big trumpet stage of corn can prevent a variety of corn pests.In addition,adding an appropriate amount of anti-aircraft additives in the process of anti-aircraft can achieve a better effect of reducing pesticide and increasing application.
