四十年代末Orawford发现昆虫能产生雷达回波。五十年代英国昆虫学家Rainev应用气象雷达观测到蝗群的活动。六十年代以来英、美、加、澳等国先后组装专用的昆虫雷达用以观测昆虫迁飞,经20年的发展已成功地研究了非洲粘虫,蝗虫,云杉卷蛾等的迁飞规律。目前的专用昆虫雷达可以观测昆虫迁飞的高度、密度、速度和方向,並能辨识混虫种类。有的已实现电脑自动控制观测、记录和运算,用以系统监测迁飞害虫做出防治决策。 我们为研究粘虫的迁飞规律,在农牧渔业
Orawford in the late 1940s found that insects produce radar echoes. In the 1950s, British entomologist Rainev observed the activities of swarms using weather radar. Since the 1960s, special insect radars have been assembled by Britain, the United States, Canada, and Australia to observe the migration of insects. After 20 years of development, the migration of armyworms, locusts and spruces have been successfully studied law. Current special insect radars can observe the height, density, speed and direction of insect migration, and can identify the types of mixed worms. Some have implemented computer automatic observation, recording and computing operations to monitor the migration of pests to make systematic control decisions. In order to study the migration rule of armyworm, we studied in agriculture, animal husbandry and fishery
