摘要:
本文首次介绍了凹纹胡蜂Vespa uelutina auraria Smith与黑尾胡蜂V.tropica ducalis Smith在实验室内饲养和自然条件下的生物学习性观察情况。结果表明，两种胡蜂在室内温度14-25 ℃，相对湿度43-89%，条件下完成一代发育所需时间为33-53天，其中卵期9-15天，幼虫期10-18天，蛹期15-20天，全年可发生三代。工蜂寿命为24-142天，雄蜂4-60天。凹纹胡蜂可在人工控制条件下越冬和自行营巢。两种胡蜂的主要天敌是蜂蝙科Stylopidae和寄绳科Tachinidae昆虫。
Abstract:
The present paper deals with the biology of wasps Vespa velutina auraria Smith,V.tropica ducalis Smith.In Kunming they could have three generations a year and overwinters in the holes of trees and soil.These Wasps complete their life cycle in laboratory at 14-15℃,the relative humidity at 43-89% between 33-53 days,in which the egg stage 9-15 days,the larval stage 10-18 days,and pupal stage 15-20 days.The longivity of workers is 24-142 days,and 4-60 days for males.The queens emerge in March and nest-building in April-May.They only do two times of nest-building in their life cycles,first,is bencath soil surface,usually in abandoned rodent burrow,second,on the tree,but for somes,their life-cycles and all within the soil.Nests are typically built in the spring by a single female.The first offspring are all workers,mating of the new queen with the males in October-November,and then the inseminated queens hibernate in the last ten-days of November.The Wasps could build their nests under the control of artificial conditions.Their important natural enemies are the parasites,Stylopidae and Tachinidae.
