Abstract

Understanding how nest parasites contribute to brood mortality rates in host species is an important step towards uncovering the potential implications for host behaviour. This can be especially important for understanding the evolution of social living, where defence against parasites is often posited as a major benefit of cooperative nesting. Only two parasitoid species have previously been reported for the only known social colletid bee, Amphylaeus morosus: the gasteruptiid wasp, Gasteruption primotarsale, and the mutillid, Ephutomorpha tyla. Here we report six additional parasitoid species of A. morosus: the gasteruptiid wasps G. atrinerve, G. globiceps, G. melanopoda and G. cinerescens; the bombyliid fly Anthrax maculatus; and the mutillid wasp Ephutomorpha aff. varipes. The mechanisms of parasitism for these eight parasitoid species are described in combination with how they operate throughout the host brood rearing period and whether benefits of social nesting vary across the season.

维多利亚独特的社会性colletid蜂Amphylaeus morosus的寄生蜂(膜翅目:Colletidae)
了解巢穴寄生虫如何导致寄主物种的幼虫死亡率是揭示寄主行为潜在影响的重要一步。这对于理解群居生活的进化尤其重要,在群居生活中,抵御寄生虫通常被认为是合作筑巢的主要好处。唯一已知的群居蜜蜂,Amphylaeus morosus,以前只报道过两种寄生性物种:gasteruptiid wasp, Gasteruption primotarsale和phutomorpha tyla。本文报道了另外6种拟寄生蜂:G. atrinve、G. globiceps、G. melanopoda和G. cinerescens;斑炭疽蝇;残蜂Ephutomorpha affes . varipes。这8种寄生蜂的寄生机制,结合它们在寄主育雏期的运作方式,以及社会性筑巢的效益是否随季节变化而变化,进行了描述。
