| 摘 要： | 在室内条件下，系统研究了粘早蛾飞翔活动与温度的关系，试验结果表明，空气相对湿度对粘虫蛾的翔活动具有显著影响，干燥或极端潮湿的条件均不利于粘虫飞翔活动，适宜的空气相对湿度为７０％－８５％。在蛾龄或温度不同的情况下，湿度对其飞翔活动的影响是一致的。在不同相对温度下由飞翔活动造成的体重和水分损失随温度的增加而减少，且蛾龄越低其损耗愈重。另外，根据测试结果讨论了粘虫在自然情况下迁悦时的空间位置等问题。

| Abstract: | The relationship between flight activity of adult oriental armyworm Mythimna separata (Walker), a well-known migratory insect pest, and relative humidity (RH) were studied in laboratory. The results showed that the flight activity of adult oriental army-worm was significantly dependant on RH conditions, both dry and too humid were unfavorable and the optimum RH for its flight ranged from 70%-85% , in despite of the different moth ages and temperatures. The consumptions of body weight and moisture content after flight decreased with the increased RH, the more young moth age, the more water loss by flight. In addition, its possible high altitude positioning in natural flight was discussed. |
