许多蛾类在连续过夜后完成长距离迁徙，但对迁徙时间和距离知之甚少。这些信息是预测迁移途径和了解其演变的关键。系留飞行实验表明，卵巢发育的水稻纵卷叶螟（Cnaphalocrocis medinalis [Guenée]）蛾加快和同步飞行的前三个晚上，其中大多数女性然后成熟交配和繁殖。因此，这只飞蛾可能会飞行三个晚上才能完成迁徙。为了验证这一假设，采用了9年的田间试验数据。medinalis采自广西南宁。前向轨迹表明，大多数飞蛾在三个晚上的飞行后到达合适的繁殖区。因此，C.这种迁徙的持续时间和距离是medinalis合理适应地理分布的适宜生境。雌蛾卵巢在连续三次夜间飞行后的发育似乎是该物种在迁徙和繁殖利益之间取得平衡的生存策略。因此，在迁徙路线和生理特征的自然选择的影响下，迁徙-繁殖能量分配的最佳平衡点逐渐形成。
Many moths finish their long distance migration after consecutive nights, but little is known about migration duration and distance. This information is key to predicting migration pathways and understanding their evolution. Tethered flight experiments have shown that ovarian development of rice leaf folder (Cnaphalocrocis medinalis [Guenée]) moths was accelerated and synchronized by flight in the first three nights, whereby most females were then matured for mating and reproduction. Thus, it was supposed that this moth might fly three nights to complete its migration. To test this hypothesis, 9 year’s field data for C. medinalis was collected from Nanning, Guangxi Autonomous Region in China. Forward trajectories indicated that most moths arrived at suitable breeding areas after three nights’ flight. Thus, for C. medinalis this migration duration and distance was a reasonable adaptation to the geographic distribution of suitable habitat. The development of female moth ovaries after three consecutive night flights appears to be a well-balanced survival strategy for this species to strike between migration and reproduction benefits. Hence, an optimum solution of migration-reproduction trade-offs in energy allocation evolved in response to the natural selection on migration route and physiological traits.
