| 中文摘要: |
| 本文明确温度、相对湿度和光照强度等3个环境因子变化对桔小实蝇 Bactrocera dorsalis(Hendel)雌、雄成虫飞行能力的影响。在不同温度、相对湿度和光照强度下,通过室内静风吊飞测试桔小实蝇雌、雄成虫的飞行距离、时间及速度。结果表明，适宜桔小实蝇飞行的温度范围是20℃-32℃，雌虫比雄虫更耐高温；最适宜飞行的空气相对湿度在60%-75%；桔小实蝇雌、雄成虫在有光照的条件下飞行，在500-2000 lux光照强度下飞行能力最强。分析表明，环境温度、空气相对湿度以及光照强度对桔小实蝇的飞行影响明显。低温或太高温对桔小实蝇飞行不利；较湿润的空气环境对桔小实蝇飞行有利，干燥或湿度过大均不利于桔小实蝇的飞行活动；光刺激是导致桔小实蝇飞行活动的基本条件，光照强度过弱或过强均不利于桔小实蝇飞行。 |
| 英文摘要: |
| This study aims to clarify the influences of the ecological factors including temperature, relative humidity and light intensity on flight activity of Bactrocera dorsalis(Hendel).The flight distance, flight duration and flight speed of B. dorsalis under different conditions of temperature, relative humidity and light intensity were assayed and analyzed by tethered flight testing.The results showed that different temperatures, humidities and light intensities could cause different flight activities of B.dorsalis.The temperature ranged from 20℃ to 32℃, the relative humidity ranged from 60% to 75% and the light intensity ranged from 500 to 2000 lux were suitable for flight activity of B.dorsalis. The females could tolerate higher temperature than the males. Low or too high temperature, dry or extreme humidity, too weak or too strong light intensity was adverse to the flight activities of B.dorsalis.The light stimulation was the basic conditions of B. dorsalis's flight activity. |
