摘要
香梨优斑螟Euzophera pyriella Yang是新疆果树重要的蛀果蛀干害虫,严重制约着香梨产业的发展。本研究通过昆虫飞行磨系统测定了香梨优斑螟成虫的飞行能力,结果表明2~5日龄香梨优斑螟飞行能力较强,4日龄飞行能力最强;吊飞14 h,平均飞行距离14.37±1.35 km,平均飞行时间9.40±0.55 h,平均飞行速度1.59±0.08 km/h。雄成虫飞行距离显著远于雌成虫,但飞行时间和速度差异不显著。雌雄成虫取食补充营养后飞行能力均有提高,但飞行距离和速度差异不显著。不同交配状态的香梨优斑螟飞行能力测定结果显示,未交配成虫飞行速度和飞行距离均高于已交配成虫,但飞行时间差异不明显。研究结果可为深入阐明香梨优斑螟飞行生物学和扩散机制提供科学依据。
Euzophera pyriella Yang is an important fruit and wood-boring pests of fragrant pear orchards in Xinjiang region,which have the latent threat to fragrant pear industry.The flight ability of the adults E.pyriella were tested by the flying mill system in laboratory.The results showed that moths of different ages had different flight ability,the flight ability of 2~5 days old moths were stronger,whereas 4 days old moths were the best.Hoisting for 14 h,the flight distance,time and speed were 14.37±1.35 km,9.40±0.55 h and 1.59±0.08 km/h respectively.The flight distance of male was significantly longer than that of female,but the difference of flight time and speed were not significant.The flight ability of both male and female adults fed with nutrition were higher than that of without nutrition,but the differences of flight distance and speed were not significant.The flight speed and distance of unmatched adults were greater than mated adults,but there were no significant difference in the flight time of adults.The results of this study lay the scientific foundation for understanding the flight biology and diffusion mechanism of E.pyriella.
