摘要
比较研究了广赤眼蜂雌蜂羽化后不同时间、有无产卵经历、有无交配经历等对其搜寻寄主和检验寄主所需的时间的影响。羽化后 48～ 72小时的雌蜂所用的搜寻时间和检验卵的时间显著比羽化后 0～ 48小时的雌蜂长 ;有产卵经历的雌蜂所用的搜寻时间和检验时间显著比没有产卵经历的雌蜂短 ;交配与否不影响雌蜂用于搜寻寄主和检验寄主的时间。
We studied the effects of post-emergence time, oviposition experience and copulation experience on the host-searching time and host-examining time in Trichogramma evenescense (Hymenoptera:Trichogrammatidae),an egg parasitoid of the cotton bollworm, Helicoverpa armigera (Lep. Noctuidae).The female parasitoid of more than 48 hours after emergence significantly spent more time than that of less than 48 hours for host-location and host-examination. The female with oviposition experience used less time than that without it in the host-location and host-examination. But copulation experience did not affect the host-locating and host-examining time.
