摘要黑纹银纹夜蛾（Autographa nigrisigna，鳞翅目：夜蛾科）是蔬菜交配干扰剂Confuser V的靶种。Nigrisigna在Confuser V处理的菜地中没有减少。作为该现象的原因之一，考虑了交配雌性动物迁移至Confuser V处理区域。因此，我们研究了雌性A. nigrisigna通过使用计算机接口actograph和飞行磨设备。飞行测量交配和未交配的个体4至6日龄记录了24小时。活动图分析结果显示，交配后的雌虫比未交配的雌虫活动更活跃，这可能与它们的产卵行为有关。飞行持续时间和飞行范围，这是由飞行磨装置测量，不断减少与年龄和交配和未交配的女性之间没有表现出显着差异，通过年龄从4到6天。这一结果表明，交配状态并没有直接影响飞行时间或范围。实验结果表明，雌虫交配后维持与交配前相同的体力，交配后的雌虫更积极地在寄主植物周围活动产卵。这些猜测进行了讨论，有关的控制A。nigrisigna通过交配中断。
ABSTRACT Autographa nigrisigna (Lepidoptera: Noctuidae) is the target species of the mating disruptant for vegetables, Confuser V. However, emergence of A. nigrisigna does not decrease in the Confuser V treated vegetable fields. As one of the reasons for this phenomenon, migration of mated females into the Confuser V treated area were considered. Thus, we studied the flight ability of female A. nigrisigna by using computer-interfaced actograph and flight mill devices. Flight measurements for mated and unmated individuals 4- to 6-d-old were recorded for 24 h. The results of the actograph assay revealed that mated females moved more actively than unmated females, possibly because of their oviposition behavior. Both the flight duration and flight range, which were measured by the flight mill device, decreased continuously with age and did not show a significant difference between mated and unmated females through the ages from 4 to 6 d. This result indicates that mating status did not directly affect the flight duration or range. From our experiments, it was suggested that females maintain physical energy after mating at the same level as before mating and then mated females locomote more actively around the host plants for oviposition. These speculations are discussed in relation to the control of A. nigrisigna by mating disruption.
