为了验证Heliothis armigera (Hubner)（鳞翅目：夜蛾科）的飞行活动符合“产卵-飞行综合征”的假设，使用系绳飞行技术，对来自印度和马拉维的雌性飞蛾在羽化后的第2、4和6晚进行了飞行测试。印度菌株的最大飞行活动发生在第2晚，马拉维菌株在3晚的飞行活动无显著差异。这种差异可以用印度女性比马拉维女性早48小时达到生殖成熟来解释。在羽化后第4晚对不同成熟状态的雄性和雌性进行飞行测试，证实了“繁殖-飞行综合征”的存在。未成熟的飞蛾比成熟的处女飞蛾和成熟的交配飞蛾飞得多。研究了马拉维棉蚜晚熟系系缚飞活动的遗传特性。通过中亲本回归，对总飞行时间（0.39 +/- SE 0.083）和最长飞行时间（0.15 +/- 0.058）的遗传力进行了显著估计。讨论了这种系留飞行数据对夜蛾野外迁徙的意义，并得出目前的实验设计不能令人满意地反映迁徙飞行的结论。
To test the hypothesis that the flight activity of Heliothis armigera (Hubner) (Lepidoptera: Noctuidae) conforms to the 'oogenesis-flight syndrome', female moths from India and Malawi were flight tested on nights 2, 4 and 6 after eclosion, using a tethered-flight technique. Maximum flight activity in the Indian strain occurred on night 2, that of the Malawian strain was not significantly different on the three nights of flight. This difference is explained by the Indian females reaching reproductive maturity c. 48 h before the Malawian females. The existence of a 'reproduction-flight syndrome' was confirmed by flight testing males and females of different maturity status on the fourth night after eclosion. Immature moths flew significantly more than did either mature-virgin or mature-mated moths. The inheritance of tethered-flight activity in a late-maturing line of Malawian H. armigera was investigated. Significant estimates of heritability, by offspring on mid-parent regressions, were obtained for both the total flight time (0.39 +/- SE 0.083) and the longest flight (0.15 +/- 0.058). The significance of such tethered-flight data to noctuid migration in the field is discussed, and the conclusion drawn that the current experimental design does not index migratory flight satisfactorily.
