【摘要】 夫暗蜂Stelis franconica Bluthgen是西鄂尔多斯荒漠地区重要传粉昆虫火红拟孔蜂Hoplitispyrrhosome的初级盗寄生性天敌.本文报道了夫暗蜂除成虫外各虫态的形态特征、生活史、幼虫的发育过程及成虫的寄生习性等生物学特性.夫暗蜂的危害主要发生在火红拟孔蜂的筑巢期,趁寄主蜂离巢采集之时,伺机潜入即将封口的寄主巢室将卵产下,幼虫孵化后杀死寄主幼虫、取食蜂粮直至完成发育.该蜂在西鄂尔多斯地区1年发生1代,以滞育的老熟幼虫茧在寄主巢内越冬.更多还原

【Abstract】 Stelis franconicais the primary cleptoparasitism predator of Hoplitis pyrrhosoma,its immature morphology,life history and biological characteristics were described.When Hoplitis left the nest,Stelis entered the nest and oviposited.The Stelislarvae killed the host larva after hatched,and developed to adults.The Stelis franconica took place one generation per year in West Erdos region and hibernated as diapause larva with a cocoon in host’s nest in the winter.更多还原
