摘要

当寄生蜂幼虫共用一个寄主昆虫时，它们会进行激烈的种间竞争，对失败者具有致命的后果。一般认为，幼虫与寄生蜂的竞争是由身体特征来解决的，比如下颌骨变大。虽然独居的寄生性幼虫通常是群居幼虫的优势竞争者，但这种生理特征不太可能对大量竞争者有效。幼虫竞争可能是由母体因素介导的，从而增加了面临种间竞争的后代的存活率，从而提高了亲代的适合度。当在宿主体内产卵时，许多雌性拟寄生物也会注射产卵液，这种液体可以抑制宿主的免疫反应，从而使后代成功发育。我们探索了两种Cotesia属黄蜂(Cotesia rubecula，一种强大的竞争者，几乎总是在与较弱的竞争者Cotesia glomerata的种间竞争中获胜)的产卵液是否也可能代表母体因素提高其后代的种间竞争能力。研究结果表明，注射风疹c的毒液和花萼液均能抑制肾小球c的卵孵化和幼虫发育。红毛囊蛇毒使肾小球球虫卵发育降低2.7倍，花萼液注射导致23%的肾小球球虫发育畸形。相反，反复注射肾小球囊孢虫卵液对风疹囊孢的发育没有抑制作用。我们的研究结果表明，母体因素可以提高寄生蜂幼虫的种间竞争能力，挑战了以往寄生蜂幼虫竞争主要通过身体对抗或幼虫分泌物来解决的假设。

期刊介绍： Ecological Entomology publishes top-quality original research on the ecology of insects and related invertebrate taxa. Our aim is to publish papers that will be of considerable interest to the wide community of ecologists who are motivated by ecological or evolutionary theory. The suitability of a manuscript will usually be assessed within 5 days. We publish full-length Original Articles as well as Reviews, Short Communications, Methods and Natural History papers. In Original Articles, we greatly prefer papers that test specific hypotheses and which have a high degree of novelty. All categories aim for innovative contributions that advance the subject of ecological entomology.
