本文报道了应用多旋翼无人机喷施农药防治甘蔗绵蚜的研究.作者根据无人机药特点,自行研究了2种微胶囊杀虫剂ALV-1501和ALV-1502和2种喷雾助剂SPA-01和SPA-02,并进行防治蚜虫试验.试验结果显示:ALV-1501剂量2.25L/hm2,药后1d防治效果为60.02％,药后5d为54.14％,ALV-1502剂量2.1L/hm2,药后1d和5d的防治效果分别为76.35％和81.35％.ALV-1501中分别添加SPA-01和SPA-02 0.6L/hm2,防治效果分别比单用提高1.42～1.47倍和1.16～1.45倍;ALV-1502中分别添加SPA-01和SPA-02 0.6L/hm2,防治效果分别比单用时提高1.23～1.25倍和1.15～1.16倍.3m/s、5m/s和8m/s三个飞行速度试验,对绵蚜的防治效果分别为:99.72％～99.97％、81.6％～99.81％和63.52％～68.77％.
