摘要
为探究茶尺蠖成虫的飞行扩散能力,本研究利用昆虫飞行信息系统,室内测定了茶尺蠖不同日龄、不同性别及交配前后成虫的飞行能力。结果表明,雌雄成虫均以2日龄的飞行能力最强,平均飞行距离分别达9.14 km和8.16 km,一次最远的飞行距离分别为2.56 km和1.93 km。雌成虫的飞行能力在3日龄时显著下降,雌雄成虫的飞行能力仅在3日龄时表现显著差异。交配对2日龄雌雄成虫的飞行能力无显著影响。
This study aimed to determine the flight capability and dispersal of adult tea geometrid, Ectropis oblique Prout. The flying speed, distance and duration of the insect were monitored using the computer-linked flight mills in the laboratory. The flight capability of the insects was at the highest 2 days after their emergence, and mating did not appear to significantly affect it. For the female and male adults, their average flying distances were 9.14 km and 8.16 km, respectively, and the longest continuous flights were 2.56 km and 1.93 km, respectively. The flight capability of tea geometrids tended to increase initially and declined significantly after they were 3-d-old, particularly for the females.
