对苹果蠹蛾的飞行能力进行了研究。（鳞翅目：卷蛾科）在实验室中通过使用计算机连接的飞行米尔斯进行测量。苹果蠹蛾表现出很大的变化，个体之间的飞行能力。我们任意定义了一个最长的单次飞行（LSF）超过5公里的长飞行者的指数。约16.7%的处女和10.0%的交配男性和20.0%的处女和7.4%的交配女性进行了这样的飞行。基于LSF和总飞行距离（TDF），我们得出结论，男性和女性的飞行能力几乎没有差异，而且在栖息地内和栖息地之间的飞行在数量和幅度上都是相似的。因此，在实地，女性可能能够进行最多11公里的飞行，其他作者报告的男性也是如此。处女蛾、交配雄蛾和处女蛾在羽化后2-7天，即生命的前三分之一，这种能力最高。交配后的雌虫在羽化后1 ~ 3天飞行能力达到高峰，这与雌虫的主要产卵期相对应。在产卵前进行了几次长时间的飞行。这些研究结果不同意与卵子发生飞行综合征所描述的其他作者，这一理论被认为不适用于苹果蠹蛾。我们的实验室研究结果进行了讨论，在一般的野外实验和假设发展的意义，长传单为这个物种。
The flight capacity of Cydia pomonella L. (Lepidoptera: Tortricidae) was measured in the laboratory by using computer-linked flight mills. Codling moths showed a large variation in flight capacity between individuals. We defined arbitrarily a longest single flight (LSF) of more than 5 km as an index for long-flyers. About 16.7% of virgin and 10.0% of mated males and 20.0% of virgin and 7.4% of mated females undertook such flights. Based on the LSF and the total distance flown (TDF) we concluded that males and females have little or no difference in flight capacity and that both the within- and between-habitat flights are similar in number and magnitude for both sexes. In the field, females are therefore potentially able to undertake flights of up to 11 km, as reported for males by other authors. This ability was highest at ages of 2-7 days after emergence, i.e. the first third of their lifetime, for virgin and mated male moths and for virgin female moths. Mated females showed peak flight capacity between 1 and 3 days after eclosion, which corresponded with the major egg-laying period. Few long flights were undertaken before oviposition. These findings do not agree with the oogenesis flight syndrome described by other authors, and this theory is believed not to apply to C.pomonella. Our laboratory results are discussed in relation to field experiments in general and hypotheses are developed about the significance of long-flyers for this species.
