摘要
笔者于2008年夏、秋、冬3个季节,每个季节在福州乌山果园对橘小实蝇进行10 d的全天观测,然后各季节分别选择3 d晴朗或多云的气候条件下所得数据,结合气象资料,分析比较该虫的日飞翔活动变化情况。结果表明,橘小实蝇在不同季节的飞翔活动节律不同,在晴到多云天气里,该虫夏季的活动高峰期为上午7:00,秋季为上午9:00,冬季则为下午15:00。橘小实蝇成虫仅在白天有光照情况下进行飞翔活动,气温、相对湿度对该虫活动有显著的影响。气温在20～30℃时,橘小实蝇飞翔活动最活跃,相对湿度大于60%时其飞翔活动最活跃。降水带来的气温与相对湿度的变化对橘小实蝇飞翔活动有显著的影响。
The daily flight activity rhythm of orient fruit fly [Bactrocera dorsalis （Hendel）] was continuously observed every hour for 10 days respectively in summer, autumn and winter in 2008 in Wushan Hill Orchard, Fuzhou. Their activity rhythm were analyzed and compared by the observations of 3 clear or cloudy days, together with meteorological data. The result showed that the adults only flied in daytime, and that the daily flight activity rhythm of the pest was not the same in different seasons; their flying peak in the sunny or cloudy weather conditions was at 7：00 am in summer, 9：00 am in autumn, and 15：00 pm in winter. The study found that temperature and relative humidity played an important role on the daily flight activity rhythm of orient fruit fly; the adults were the most active at temperature of 20 ~30 ℃ and the humidity up to 60%; the change of temperature and relative humidity due to rainfall had a significant impact on the activity of orient fruit fly.
