黑盾胡蜂的生物学习性

Biological Habit of Vespa Bicolor

对黑盾胡蜂 (Vespabicolor)的生物学习性进行了研究 .结果表明 :出蛰雌蜂 5月中旬觅址筑巢 ,单母建群 ,历时36d建成具 34个巢房的小巢 ,此时雌蜂兼备职蜂和后蜂职能 ;该蜂卵期 3.5～ 5 .5d ,幼虫期 10～ 12d ,蛹期 10 .5～ 12 .5d ,完成发育需 2 4～ 30d ,并与气温密切相关 ;雌蜂日外勤晴天多达 4 2次 ,每次捕食外勤费时 6～ 2 2min ;职蜂出房后第 3天开始外勤 ,雌蜂随即停止外勤专司产卵 ,1a仅一世代 ,12月中旬弃巢结团越冬 .黑盾胡蜂亲代个体群居分工合作有利于生存和种族繁衍 .

Vespa bicolor is a kind of social insect in vespidae.Its biological habit research in northeastern Fujian Province shows:the female Vespa bicolor finishes its hibernation in the mist of May,and then finds a place to nidificate.Its haplometrosis takes 36 days to finish a 34-comb nest and the female wasp plays both roles of the worker wasp and the queen wasp.Its ova period lasts 3.5～5.5 d;its larva period lasts 10～12 d;its pupa period takes 10.5～12.5 d;its development period needs 24～30 d (it is closely related to temperature).Daily outing frequency of the female wasp has close relation with the local weather:its maximum can reach 42 times,per time is 6～22 min;worker wasps begin their field work when they are out of dormancy for three days;and the female wasp stops going out and invests all its energy in laying eggs (it only has a generation per year,they abandon their nests to hibernate in the mist of December).Parental generation living in groups and cooperating together contribute to Vespa bicolor′s existence and reproduction.
