摘　　要：利用昆虫飞行数据微机采集系统对草地螟阿格姬蜂Agrypon flexorius(Thunberg 5)个日龄的飞行能力进行了测定。结果表明,不同日龄的草地螟阿格姬蜂飞行能力存在显著差异,1日龄飞行能力较弱,3日龄开始增强,5日龄达到最高峰;对5日龄成虫的4个温度和3个湿度梯度进行研究发现,适于飞行的温度为20℃,相对湿度为60%。温度在28℃以上,其飞行能力明显降低。温度在20℃时,草地螟阿格姬蜂雌虫的平均飞行时间、飞行距离、飞行速度分别为1.123 h、0.990 km、0.849 m/s;雄虫的平均飞行时间、飞行距离、飞行速度分别为1.250 h、0.929 km、0.838 m/s。在相对湿度40%、60%和80%时,雌虫的飞行时间分别为0.354、0.829和0.176 h;雄虫的飞行时间分别为0.428、1.071、0.313 h;飞行距离与相对湿度的关系与飞行时间相似。飞行速度随温度的增高而减小,在相对湿度60%左右时,平均飞行速度较快。Flight capacity of 5 age groups of Agrypon flexorius Thunberg was tested using a computer monitored flight mill system. The results show that adult of different ages showed different flight ability, being the weakest in 1 day old adults and the strongest in 5 day old adults. Further studies show that 20℃and 60%RH was suitable for adult flight in 5 day old A. flexorius. When temperature reached above 28℃, flight was decreased obviously. At 20 ℃, average flight duration, flight distance and flight speed were 1.123 h, 0.99 km, and 0.849 m/s, respectively, for females and 1.25 h, 0.929 km, and 0.838 m/s, respectively, for males. At 40%, 60%and 80%RH, flight duration were 0.354, 0.829 and 0.176 h for females, respectively, and 0.428, 1.071 and 0.313 h, respectively, for males. The relation between flight distance and humidity was similar to that between flight duration and humidity. At increased temperature, flight duration was prolonged and flight speed was decreased. Flight speed was greater at about 60%RH.
