上海青蜂(Chrysis shanghaiensis Smith)是黄刺蛾茧期的主要寄生性天敌。笔者曾多次观察到该蜂的寄生产卵过程,近年来结合室内饲养对其产卵习性和发生发育作进一步研究,现将结果报道如下(附图见封面照片)。1 产卵习性 上海青蜂成虫寻找到黄刺蛾茧后,先绕周围茧爬行一周,选好合适的位置,用大颚在坚硬的茧上咬一个直径0.8mm左右的产卵孔(图左上),咬此孔最短37分钟,最长1小时43分钟,咬孔后,掉转身将产卵管插进孔内产卵(图左下)这一过程约3—11分钟,大多数一次完成,也有的再次调转身用口器对产卵孔进行“修理”后再次产卵。产卵后用口器封 Chrysis shanghaiensis Smith is the major parasitic natural enemy of the sting. The author has repeatedly observed the bee parasitic egg production process, in recent years combined with indoor feeding its habit of spawning and development for further study, the results are reported below (see the cover photo). 1 spawn habitat Shanghai Green Bee adults to find yellow sting moth cocoon, first around the cocoon crawling a week, select the right location, with a large jaw on the hard cocoon bite a diameter of about 0.8mm oviposit ), Bite this hole for a minimum of 37 minutes, up to 1 hour and 43 minutes, after bite hole, turn and turn the ovipositor into the hole spawning (bottom left) This process takes about 3-11 minutes, most of the time to complete, Some also turned around again with the mouth of the spawning hole to “repair” again after spawning.
