中文摘要：
【目的】 为明确斑翅果蝇Drosophila suzukii Matsumura和黑腹果蝇Drosophila melanogaster飞行能力的差异。【方法】 利用昆虫飞行磨系统对斑翅果蝇和黑腹果蝇雌、雄虫各7个日龄分别进行22-24 h连续吊飞试验，并对相关飞行参数进行显著性检验。【结果】 两种果蝇在1日龄时的飞行时间、飞行速度和飞行距离均最小，随着日龄的增加，飞行能力出现两个高峰。斑翅果蝇的第一个高峰出现在2日龄，黑腹果蝇的第一个高峰出现在3日龄；两种果蝇飞行能力的第二个高峰均出现在15日龄，此时雌、雄虫的累计飞行距离均最大。斑翅果蝇雌、雄虫15日龄的总飞行距离最远，而黑腹果蝇雌虫15日龄、雄虫3日龄飞行距离最远、飞行时间最长。【结论】 斑翅果蝇和黑腹果蝇的飞行能力与日龄和性别均有关系，且两种果蝇雌虫的飞行能力均强于雄虫。
英文摘要：[Objectives] To compare the flight ability of Drosophila suzukii and D. melanogaster. 【Methods】 A flight mill system was used to measure the flight ability of 1-7 day-old male and female D. suzukii and D. melanogaster for 22-24h, after which differences in relevant flight parameters were tested for significance. 【Results】 One day-old adults had the shortest flight duration, velocity and distance. There were subsequently two peaks in flight capacity; the first at 2 days of age in D. suzukii and at 3 day of age in D. melanogaster, and the second at 15 days of age when the longest total flight distance was recorded for females of both species. Fifteen day old female and male D. suzukii, and female D. melanogaster, had the longest total flight distance, whereas the longest flight distance, and flight time, recorded for male of D. melanogaster was achieved by 3 day old individuals. 【Conclusion】 The flight ability of D. suzukii and D. melanogaster are related to age and sex and females of both species have stronger flight capacity than males.
