摘    要:温度对甜菜夜蛾飞行能力有显著的影响(P<0.05)。在16~32℃内,成虫均能进行正常的飞行活动。24℃下的成虫飞行能力最强,在15 h的吊飞飞行中,成虫飞行距离最远(37.14 km)、飞行速度最快(0.87 m/s)、飞行时间最长(11.73 h)。温度低于20℃或高于28℃时,其飞行能力均显著降低。甜菜夜蛾在不同温度下飞行时对主要能源物质(甘油三酯)的利用效率不同。在较适宜的温度下,尽管成虫飞行消耗的甘油三酯较多,但单位飞行距离所消耗的甘油三酯却较少,即利用效率较高,表明成虫飞行能源物质利用效率的不同是导致其在不同温度下飞行能力产生差异的主要原因之一。

关 键 词:甜菜夜蛾  温度  飞行能力  甘油三酯

Abstract:Flight capacity and triglyceride utilization of the beet armyworm, Spodoptera exigua adults during flight at temperatures from 16℃ to 32℃ were investigated. The moths flying at 24℃ exhibited the greatest flight distance and longest flight duration although they could fly normally at all temperatures tested. Adult flight capacity significantly declined at temperatures below 20℃ or above 28℃.These results suggested that the temperature most suitable for their flight be about 24℃. Utilization of energy substrate by the moths during flight was greatly affected by ambient temperature. Variations in flight capacity of adults at different temperatures were primarily caused by differences in triglyceride utilization efficiency by the moth, i.e., the triglyceride utilized for a given flight distance at suitable temperature was much less than at the unsuitable temperature, which might be one of the major reasons for difference in flight capacity of the moth at different flying temperature.
Keywords:Spodoptera exigua  temperature  flight capacity  triglyceride
