【摘要】 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．更多还原

【Abstract】 The previous conclusions of ricei leaf roller relating to flight behaviors were summarized. The perameters of trajectory analysis were determined by using the results of releasing-catching experiments and through the trajectory analysis under different composition of the presuming flight parameters. The results displayed that the exact flight parameters were: take-off at 20 o’ clock, succession flying for 8～9 hours each night. Data of this insect of 3 years in 7 representative counties selected from Huaihe and Yangtze river rice areas were applied in the back and forward trajectory models to utilize and verify the above parameters. The method to determine the source regions was also given in detail. The limitation and further research fields of trajectory analysis were also discussed.更多还原
