黑盾胡蜂单母建群习性的观察

通过引蜂筑巢研究黑盾胡蜂VespabicolorFabricius单母建群的生物学习性。结果表明 :母蜂在最初 3只子代工蜂羽化之前兼负蜂王和工蜂的职能 ,建成外包巢壁内具有 3 4个巢房的小巢 ,饲育的幼虫数不超过 1 7只 ,各虫态历期分别为卵期 5 5d ,幼虫期 1 2d,蛹期 1 2 5d ;母蜂日外勤飞翔次数与天气相关 ,晴天可达 42次 ,其中近 80 %为捕食。作者认为 ,黑盾胡蜂单母建群时期可能是其生活史中既脆弱又关键的阶段。

Observation on the bionomics of the haplometrosis of Vespa biocolor

During attracting wasps and nidification, the biological habit of the haplometrosis of Vespa bicolor Fabricius was observated.The results showed that the female wasp before the eclosion of three warker wasps, was fanctioning as both the queen wasp and the worker wasp and built a small nest with 34 combs. At the same time the female wasp did not bring up more than 17 larvae. The developmental phases of the egg, lerval and pupal stage were 5\^5,12 and 12\^5 days respectively.The time numbers per day that the famale wasp went out are related to the weather. In a fine day, it may go out 42 times, of 80% are for food hunting.The haplometrosis stage of V.bicolor may be a weak and crucial stage in its life history.
