平唇原胡蜂(Prevespa barthelemyi)剖巢观察

Nest Anatomical Observation of Prevespa barthelemyi

对平唇原胡蜂营巢地和蜂巢的结构进行了观察,结果表明:(1)蜂巢中部较大的巢脾为主要繁殖区;(2)幼虫和工蜂所占比例最高,占全巢各虫态总数的70%左右;(3)巢中成熟个体中,除蜂后外其余全部为雌性工蜂;(4)由于当地气候适宜,越冬期的低温虽使其活动能力下降,但不会引起大量死亡,可以在原巢址内越冬。

Prevespa barthelernyi, belonging to family Vespidae, is a kind of social insect. We observed the structure of its nest and habitat in details. The results indicated that： （1） Those combs in the middle of nest were the major breeding areas; （2） Larvae and workers took up the most of the whole nest, with the ratio of more than 70 percent; （3） All the mature wasps, except for the queen, were female workers; （4} Although the activity of wasps, owing to the low temperature in the wintering period, decreased to some degrees, mass death didn＇t happen; thus, P. barthelemyi could live through the winter in the original nest.
