总结并分析了稻纵卷叶螟有关迁飞过程方面的研究成果，并利用标记回收试验资料，通过对飞行参数的组合试验研究，具体确定了稻纵卷叶螟轨迹分析参数，即起飞时间为每晚２０：００、续航时间为每晚８～９ｈ．同时．选择了江淮稻区有代表性区域的７个地点的３ａ虫情资料，利用口推和顺推轨迹分析模型，对上述参数进行了实际应用和验证．并得出了具体的飞行天数为２—８ｄ，平均５ｄ，还具体探讨了确定虫源地的方法．另外．对轨迹分析的终止条件以及在确定轨迹分析参数过程中遇到的一些问题也作了深入的讨论．
The paper summarizes and analyzes the research results on the migration process of the rice leaf roller and utilizes the experimental data of the marker recovery and the experimental study of the flight parameters to determine the parameters of the tracked rice leafroller trajectory analysis, 20:00 every night, life time is 8 ~ 9h per night. Simultaneously. The data of 3a insects in 7 locations in the representative area of Jianghuai rice area were selected and the above parameters were applied and verified by using the model of push and push trajectory analysis. And got the specific flight days 2-8d, an average of 5d, also specifically discussed to determine the source of the method. In addition. The termination conditions of trajectory analysis and some problems encountered in determining trajectory parameters are also discussed in depth.
