摘　　要：【目的】研究小型无人机超低量喷雾防治玉米螟的田间药效及经济效益评价,为发展科学合理、适宜新疆生产实际的玉米螟高效飞防技术提供指导。【方法】考虑大田实际防效、挽回产量损失、成本投入、纯增效益以及投入产出比等因素,对不同药剂处理进行系统评价,提出新疆荒漠绿洲生态区玉米螟飞防使用的最佳药剂及用量。【结果】34%乙基多杀菌素·甲氧虫酰肼(斯品诺)450.0 m L/hm^2的防效、可挽回产量、纯增效益及投入产出比最高,分别达89.60%、6 050.85kg/hm^2、9 264.30元/hm^2和1∶22.22;其次是阿维·氯苯酰(亮泰)悬浮剂,喷施600 m L/hm^2的防效、可挽回产量、纯增效益及投入产出比分别为84.18%、6 041.25kg/hm^2、9 219.0元/hm^2和1∶20.62;再次是20%氯虫苯甲酰胺(康宽)悬浮剂,喷施90.0 m L/hm^2的防效、可挽回产量、纯增效益及投入产出比则为81.01%、5 412.15 kg/hm^2、8 368.50元/hm^2和1∶28.76。此外,添加飞防专用助剂可使田间防效提升高达27.58%。【结论】在生产上玉米螟飞防使用的最佳药剂种类及用药量为,34%乙基多杀菌素·甲氧虫酰肼(斯品诺)悬浮剂450.0 m L/hm^2、阿维·氯苯酰(亮泰)悬浮剂600.0m L/hm^2、20%氯虫苯甲酰胺(康宽)悬浮剂90.0 m L/hm^2、45%甲维·虱螨脲(普克猛)水分散粒剂225.0 g/hm^2,同时添加飞防专用助剂。【Objective】To study the control effects of Pyrausta nubilalis and evaluating economic benefit by ultra-low volume spraying by unmanned aerial vehicle（UAV） in fields in the hope of providing guidance for developing high-efficiency flight control technology which might be scientific,reasonable and suitable for Xinjiang practical production. 【Method】By comprehensive consideration of factors including control effect,retrieved yield loss,insecticide cost input,net benefit and input-output ratio in fields,systemic evaluation of different kinds of chemical treatment was provided for optimal pesticide and dosage in flight control for Pyrausta nubilalis in Xinjiang desert and oasis ecological zone. 【Result】34% spinetoram and methoxy-fenozide（Sipinnuo） at dosage of 450. 0 m L/hm2 was the best in the control effect,retrieved yield loss and input-output ratio,which were up to 6,050. 85 kg/hm2,9,264. 30 yuan/hm2 and 1∶ 20. 62,respectively; The second one that produced better result was avermectin and cholorantraniliprole（Langat） at dosage of 600 m L/hm2,control effect,retrieved yield loss and input-output ratio,which were up to 84. 18%,6,041. 25 kg/hm2,9,219. 0 yuan/hm2 and 1∶ 20. 62,90 m L/hm2,8,368. 5 yuan/hm2 and 1∶ 28. 76,respectively. In addition,the addition of special agents for flight control improved the effectiveness of the field control up to 27. 58%.【Conclusion】Optimal use of insecticcdes and the dosage of corresponding insecticide in practical production was proposed as follows： 34% spinetoram and methoxyfenozide（Sipinnuo） SC 450. 0 m L/hm2,avermectin and cholrantraniliprode（Laangat） SC 600. 0 m L/hm2,20% chlorantranili prole（Coragen） SC 90 m L/hm2,45% emanectin benzoate and lufenuron（Pukemeng） water dispersidble granules 225. 0 g/hm2,and special agents for flight control should be added simultaneously.
