Biological aspects and demographic parameters of Cephalonomia stephanoderis Betrem (Hymenoptera: Bethylidae) and Prorops nasuta Waterston (Hymenoptera: Bethylidae) parasitoids of the coffee berry borer (CBB), Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae: Scolytinae) were investigated using diet-reared CBB hosts. Developmental time from eggs to adults, oviposition, and postoviposition period were comparable for both parasitoids. However, P. nasuta had a considerably longer preoviposition and longevity period averaging 17.3 and 63.1 d, respectively. The reproductive rate for C. stephanoderis was 46.1 daughters per female with a mean generation time of 47.4 d, whereas P. nasuta had a reproductive rate of 18.3 daughters per female in a mean time of 58.6 d. Oviposition behavior was also different with C. stephanoderis typically ovipositing on CBB prepupae and pupae, while P. nasuta preferred prepupae and second-instar CBB larvae. An abridged cohort life table for both parasitoids was constructed for growth rates estimations.
利用以特定食物饲养的咖啡果小蠹寄主,对咖啡果小蠹(Hypothenemus hampei (Ferrari),鞘翅目:象甲科:小蠹亚科)的两种寄生蜂——斯氏长尾啮小蜂(Cephalonomia stephanoderis Betrem,膜翅目:肿腿蜂科)和长角啮小蜂(Prorops nasuta Waterston,膜翅目:肿腿蜂科)的生物学特性和种群统计学参数进行了研究。两种寄生蜂从卵到成虫的发育时间、产卵期和产后时期相当。然而,长角啮小蜂的产卵前期和寿命明显更长,平均分别为17.3天和63.1天。斯氏长尾啮小蜂的繁殖率为每雌46.1头雌蜂,平均世代时间为47.4天,而长角啮小蜂的繁殖率为每雌18.3头雌蜂,平均时间为58.6天。产卵行为也有所不同,斯氏长尾啮小蜂通常在咖啡果小蠹的前蛹和蛹上产卵,而长角啮小蜂则更喜欢前蛹和二龄咖啡果小蠹幼虫。构建了两种寄生蜂的简略群组生命表以估计增长率。
