1973—1977年,本组与广西各协作单位根据室内外饲养、越冬情况调查、田间系统赶蛾和卵巢解剖、高山和海岛空中网捕、海面观察、人工标记释放和回收、天气和水稻生长情况分析,证明稻纵卷叶螟是一种远距离迁飞的昆虫,并明确在广西的迁飞规律。为了及早应用于生产,我们从1977年开始用这一规律进行该虫的预测预报。几年的实践证明,它大大提高了该虫预测预报的准确 From 1973 to 1977, the cooperative units in Guangxi and Guangxi conducted surveys on indoor and outdoor rearing, winter moth surveys, field system moth and ovary dissection, alpine and island air net catching, surface observation, artificial marker release and recovery, weather and rice growth Analysis, to prove that rice leaf roller is a long-distance migratory insects, and clear rules of migration in Guangxi. In order to be applied to the production as early as possible, we use this rule from 1977 to forecast the pest. Years of practice has proved that it greatly improves the accuracy of the worm prediction
