摘　　要：在甘孜州高寒牧区应用通用航空AS350B3直升飞机防治草原蝗虫试验,结果表明:直升机超低容量喷雾具有防治区域精确、喷雾均匀、效率高、防效好的特点,有利于改善高寒牧区草原虫害防治效率偏低的现状,是高寒牧区控制草原蝗虫危害的有效手段。1. 5%苦参碱可溶液剂应用直升机防治草原蝗虫防效可达到92. 38%;背负式喷雾器人工防治平均防效为93. 00%。两者防效相当,但直升机防治效率远远高于人工防治。The experiment of controlling locusts with helicopter AS350 B3 in alpine pastoral area of Ganze prefecture showed that the helicopter ultra-low volume spraying had the characteristics of precise control area,uniform spraying,high efficiency and good control efficiency. It was beneficial to improve the low efficiency of grassland pests control in alpine pastoral areas,and it was an effective way to control grassland locusts harm in alpine pastoral areas. The control efficiency of grassland locusts control could reach 92. 38% by using helicopter with 1. 5% matrine solution. The average control efficiency of knapsack sprayer artificial control could reach 93. 00%. Both of them had the nearly same control efficiency,but the control efficiency of helicopter was much higher than that of manual control.
