Mosquitoes have developed specialized oviposition strategies that allow them to develop in a wide variety of aquatic habitats. Environmentally cued hatching traits may also play an important role in the successful colonization of some larval habitats, but this subject has remained largely unexplored in Culicidae. Aedes atropalpus (Coquillett) is an autogenous rock pool specialist that may maintain unique adaptations for oviposition and egg hatching. We investigated the egg-laying strategies of Ae. atropalpus exposed to standard (non-diapausing) rearing conditions and diapause-inducing conditions and tested the impact of physical agitation on egg hatch rates by exposing floating and submerged eggs to physical agitation treatments. The results of the oviposition experiment indicate that Ae. atropalpus females primarily lay non-diapausing eggs directly onto the water surface and lay diapausing eggs directly on solid surfaces. The egg-hatching experiment demonstrated that physical agitation significantly increases Ae. atropalpus hatch rates. Floating and submerged eggs responded similarly to the agitation treatment. These data suggest that oviposition behaviors based on both egg diapause status and environmentally-cued hatching strategies may be important adaptations for Ae. atropalpus in riverine rock pools.

滞育影响白纹伊蚊的产卵行为和物理卵孵化线索（双翅目：Culicidae）：可能影响河流岩池成功定殖的特征

蚊子已经制定了专门的产卵策略，使它们能够在各种各样的水生栖息地中发育。环境提示的孵化特征也可能在一些幼虫栖息地的成功定殖中发挥重要作用，但这个主题在库利科动物中仍然很大程度上未被探索。Aedes atropalpus (Coquillett) 是一种自体岩池专家，可以保持对产卵和卵孵化的独特适应性。我们研究了Ae的产卵策略。回眼暴露于标准（非滞育）饲养条件和滞育诱导条件，并通过将漂浮和浸没的鸡蛋暴露于物理搅拌处理来测试物理搅拌对鸡蛋孵化率的影响。产卵实验的结果表明，Ae。atropalpus雌性主要将非滞育卵直接产在水面上，并将滞育卵直接产在固体表面上。孵化实验表明，物理搅拌会显着增加Ae。atropalpus 孵化率。漂浮和浸没的鸡蛋对搅拌处理的反应相似。这些数据表明，基于卵滞育状态和环境提示的孵化策略的产卵行为可能是重要的适应埃。atropalpus在河流岩石池中。
