| 摘 要： | 迁飞是草地贪夜蛾Spodoptera frugiperda(J.E.Smith)快速扩散的生物学基础。本研究对草地贪夜蛾1~13日龄成虫飞行参数的测定表明:1~5日龄的个体具有较强的飞行能力,3日龄达到峰值后逐渐下降。3日龄个体吊飞24 h,平均飞行距离、飞行时间和飞行速度分别为(29.21±1.54)km、(11.00±0.47)h和(2.69±0.10)km/h。1~11日龄成虫的振翅频率无显著差异,平均振翅频率范围为42.39~44.64 n/s。相同日龄雌、雄蛾的飞行距离和飞行时间均无显著差异,但1日龄雄蛾的平均飞行速度显著大于雌蛾。补充营养组成虫的飞行距离和飞行时间显著高于未补充营养组。研究结果为深入阐明草地贪夜蛾的飞行生物学和迁飞机制提供了科学基础。

| Abstract: | Migration is the biological basis for the rapid spread of Spodoptera frugiperda (J. E. Smith). In this study, the flight parameters of 1-13-day-old moths were measured using a flight mill system. The results showed that 1-5-day-old adults had strong flight capacities, with the 3-day-old moth reached the peak and then gradually declined. The average flight distance, flight duration and flight velocity for 3-day-old adults in a 24 h tethered flight were (29.21±1.54)km, (11.00±0.47)h and (2.69±0.10)km/h, respectively. There was no significant difference in the wingbeat frequency among 1-11-day-old adults, which took a range from 42.39 n/s to 44.64 n/s. There was no significant difference in flight distance and flight duration between male and female moths at the same age, but the average flight velocity of the first day male was significantly faster than female at the same age. The flight distance and flight duration of the adult supplied with complemental nutrition were significantly higher than those of adults without feeding. The results provide a scientific basis for further elucidating the flight biology and migratory mechanism of S. frugiperda. |
