用保幼激素类似物甲氧普烯（JHM）处理迁飞性东方粘虫Mythimna separata（步行者）后第1 ~ 6天，比较其飞行能力和能量物质含量。JHM处理蛾的飞行能力，通过12小时的系留飞行试验确定，显着低于对照组，尽管它可能与它们的年龄和性别不同。处理后第1 ~ 3天，处理间蛾的飞行能力差异不显著，但第4 ~ 6天，处理间蛾的平均飞行时间和飞行距离差异显著。在处理之间的相同阶段对长飞行器的评估也支持这一发现。JHM处理蛾的飞行能力也因性别而异。从第1天至第3天，JHM给药雌性动物的飞行时间并不少于对照组，但从给药后第4天至第6天，其飞行时间显著少于对照组。然而，在整个试验期间，JHM给药雄性的飞行能力不弱于对照组。JHM处理组与对照组能量物质水平的比较表明，JHM可能直接作用于甘油酯代谢，进而影响飞行能力。此外，在系留飞行试验期间的大部分时间里，接受治疗的雄性成年动物中较高水平的甘油酯使其飞行能力提高到比对照组更强的水平。但对雌、雄成虫糖原含量的影响不显著。因此，可以得出结论，JH的水平是一个关键因素调节迁移行为的军队蠕虫蛾。除影响甘油酯代谢外，本文还讨论了JH在决定迁飞行为中可能发挥的其他生理作用。
Abstract The flight capacity and contents of energy substances in the moths of migratory Oriental armyworm, Mythimna separata (Walker)dosed with juvenile hormone analogue methoprene(JHM) were compared with the normal moth through day‐1 to day‐6 after the treatment. The flight capacity of JHM‐treated moths, as determined by a 12‐hours tethered‐flight test, was significantly lower than that of the controls, although it might differ with their age and sex. The moth's flight capacity between the treatments was insignificantly different from the first to 3rd day after the treatment but was significantly different from the 4th to 6th day either in the mean flight duration or in distance. Evaluation of the long fliers at the same stages between the treatments also supported this finding. Flight capacity of the JHM‐treated moths also differed with the sex. The JHM‐treated female did not fly less than the control from day‐1 to day‐3, but did significantly less from day‐4 to day‐6 after the treatment. The flight capacity of the JHM‐treated males, however, was not weaker than that of the control throughout the test period. Comparison of the levels of energy substances in the JHM‐treated adults and the controls showed that JHM may directly acted on metabolism of glyceride, which in turn affected flight capacity. Furthermore, higher levels of glyceride in the treated male adults raised their flight capacity to a stronger levels than the control in most of the days of tethered‐flight test period. Contents of glycogen, however, were insignificantly affected by JHM in both male and female adults. In might therefore be concluded that levels of JH is a critical factor regulationg migratory behavior in the army worm moth. In addition to affect metabolism of glyceride, other possible physiological roles that JH played in determining migrattory behavior are also discussed.
