摘要
为了分析我国稻飞虱(褐飞虱Nioaparvata lugens,白背飞虱Sogatella fercifera)迁飞的路径,以确定我国各稻区稻飞虱迁入种群的虫源地,本文在综合各种轨迹分析模型的基础上,提出一种计算稻飞虱迁飞轨迹的实用方法。通过实际虫情与气象资料的验证表明该方法可用于稻飞虱及与稻飞虱迁飞行为相似的中小型迁飞昆虫的轨迹分析及异地预测。
In order to analyze the pathways of migrating rice planthoppers ( Nilaparvata lugens , Sogatella fercifera ) and to find out their resource areas, a method based on other trajectory analysis models was put forward to calculate accurate migration pathways of rice planthoppers. The result that was calculated with actual meteorological data indicated that the method is a useful trajectory analysis tool for insect migration researches and inter-regional pest forecasting practice.
