【摘要】 为了在美国白蛾防治上推广应用无人机施药技术，在该虫发生区域进行了无人机和地面机械施药技术防治美国白蛾对比试验。试验结果显示：美国白蛾幼虫无人机施药防治效果可达93.2%，地面机械施药防治美国白蛾幼虫防治效果为92.4%，两种施药技术防效均显著，但地面机械防治成本高于无人机防治成本，建议根据美国白蛾发生区的实际情况推广应用无人机防治技术。更多还原

【Abstract】 In order to promote the application of unmanned aerial vehicle(UAV) pesticide application technology in the prevention and control of hyphantria cunea, a comparative experiment between UAV and ground mechanical pesticide application technology is carried out in the area where the insect occurs. The test results show that UAV spraying has a 93.2% control effect against hyphantria cunea larvae, ground mechanical spraying has a 92.4% control effect against hyphantria cunea larvae, and both application techniques have significant control effects, but the cost of ground mechanical control is higher than the cost of UAV control. It is suggested to popularize and apply UAV control technology according to the actual situation of hyphantria cunea occurrence area.更多还原
