| 摘 要： | 研究了阿里山潜蝇茧蜂与长尾潜蝇茧蜂的种间竞争．结果表明：长尾潜蝇茧蜂不能识别被阿里山潜蝇茧蜂寄生过的寄主幼虫．寄主供阿里山潜蝇茧蜂寄生后再供长尾潜蝇茧蜂寄生，会造成寄主幼虫及蛹的大量死亡，在存活下来的寄主羽化出来的寄生蜂中阿里山潜蝇茧蜂占多数，总的羽化率（75．95％）比阿里山潜蝇茧蜂或长尾潜蝇茧蜂单独寄生时的羽化率（63．43％或62．25％）都高．寄主供阿里山潜蝇茧蜂寄生后间隔不同时间再供长尾潜蝇茧蜂寄生，各处理问长尾潜蝇茧蜂的羽化率无显著差异；时间间隔为132h时，寄生蜂总的羽化率最高，为86．63％．

| Abstract: | Interspeeitlc competition between Fopius arisanus （Sonan） and Diachasmimorpha longicaudata （Shmead） were studied. The results showed that D.longicaudata could not discriminate the hosts which had previously been parasitized at egg stage by F. arisanus. Most of the hosts died, which were parasitized by F. adsartus at egg stage firstly and parasitized by D.longicauda see oncUy, and the emerged adults from the host pupae were mostly F. arisanus, total emergence percentage of parasitoids was higher than that exposed to only one species. The ,exnergence percentage of D.longicaudata had no significant differences among the interval extension. With the interval of 132 h, the total emergence percentage of parasituicls was 86.63%. |
