使用系留飞行技术研究了衰老和雌性交配状态对棉铃虫（Hubner）飞行潜力的影响，棉铃虫是从印度南部的木豆作物中采集的幼虫。 在喂食糖溶液的非交配蛾中，从成虫羽化后的第一个晚上开始，每晚总飞行时间和最长连续飞行时间增加到第 4 晚，并保持在这一水平，直到至少第 6 晚。卵巢成熟迅速，77% 的未交配蛾在第三晚开始产卵。 根据现场证据，如果当地有带有花蜜或含糖分泌物的植物，大多数雌性很可能会在第三或第四晚交配。 与年龄相仿的未交配雌性相比，成功交配的雌性的总飞行时间减少了 15 倍，最长连续飞行时间减少了 28 倍。 由于在野生成虫羽化期间，当地存在适合成虫取食和产卵的寄主植物，因此在研究的种群中不太可能发生同步的繁殖前迁移。
The effects of ageing and female mated status on the flight potential of Helicoverpa armigera (Hubner), collected as larvae from a pigeonpea crop in southern India, were investigated using a tethered-flight technique. In non-mated moths fed sugar solution, from the first night after adult eclosion, the durations of both total and longest continuous flight per night increased up to night 4 and remained at this level until at least night 6. Ovarian maturation was rapid with 77% of unmated moths having commenced oviposition by the third night. On the basis of field evidence it is likely that most females would be mated by the third or fourth night, provided plants with nectar or sugary exudates were locally available. In successfully-mated females a 15-fold decrease in total flight duration and a 28-fold decrease in longest continuous flight duration was observed in contrast to non-mated females of similar age. As host plants suitable for adult feeding and oviposition were locally available during the time of feral adult emergence, synchronous pre-reproductive migration was unlikely to occur in the population studied.
