摘要
运用M-4小型飞机和Y-5大型飞机喷洒药剂防治美国白蛾的试验结果表明:飞机喷药比常规地面机械喷雾防治成本低,M-4小型飞机比Y-5大型飞机防效好,第1代和第2代美国白蛾防控检查验收平均有虫株率分别为0.9‰和0.7‰。分析探讨了影响飞防质量的几个关键因素,建议大力推广飞机防治美国白蛾技术。
The result of aerial spray against Hyphantria cunea （Drury） with M-4 light airplane and Y-5 large airplane showed that the cost of aerial control was lower than that of the conventional mechanical control on the ground. The control effect of M-4 light airplane was better than that of Y-5 large airplane and the average attacking rate was 0. 9‰ and 0. 7‰ respectively for the first and second generations of the pest. The key factors affecting the control quality were analyzed and the technology of airplane spray against Hyphantria cunea （Drury） was suggested for popularization.
