果蝇蛹寄生虫在幼虫和成虫阶段对热浪的不同反应

寄生虫的生活史分为寄生在寄主无脊椎动物体内或寄生在寄主无脊椎动物身上的未成熟阶段和自由生活的成虫阶段。我们测试了两种世界性果蝇蛹寄生虫 Pachycrepoideus vindemiae（膜翅目：Pteromalidae）和 Trichopria drosophilae（膜翅目：Diapriidae）在幼虫和成虫阶段分别暴露于 35 和 40°C 热浪时的表现。此外，我们还测试了幼虫阶段的热硬化是否会影响成虫对热浪的耐受性。我们没有发现在幼虫阶段经历过热硬化的成蜂的耐热性有明显提高。经历过35°C热浪的嗜水蝇幼虫发育时间较长，但存活下来的个体与未经历过升温的个体相比，寿命和繁殖力没有明显下降。相比之下，35°C热浪造成的嗜水蝇成虫死亡率较低，但存活下来的个体寿命和繁殖力明显下降。我们的研究清楚地揭示了两种寄生虫的幼虫期和成虫期对热浪的不同反应，并强调了热耐受性的个体发育差异对预测寄生虫分布和种群动态的重要性。

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.
