The crested auklet, Aethia cristatella, emits a class of aldehydes shown to be potent invertebrate repellents when used by heteropterans against their predators. Our aim was to determine the efficacy of these aldehydes against mosquitoes in the laboratory. Synthetic analogues of the auklet odorant were strongly repellent to mosquitoes in controlled laboratory trials. Furthermore, the efficacy was similar to previous reports for commercial mosquito repellents. These results, in combination with a previously published study, show that constituents of the aldehyde odorant are broad spectrum in efficacy against ectoparasitic arthropods of birds. Our report is the first empirical evidence for an endogenous mosquito repellent in birds.
冠海雀（Aethia cristatella）会释放出一类醛类物质，研究表明，当半翅目昆虫用其抵御捕食者时，这类醛是有效的无脊椎动物驱避剂。我们的目的是在实验室中确定这些醛对蚊子的驱避效果。在对照实验室试验中，冠海雀气味剂的合成类似物对蚊子具有很强的驱避作用。此外，其效果与先前关于商用驱蚊剂的报道相似。这些结果与之前发表的一项研究相结合，表明醛类气味剂的成分对鸟类的体外寄生节肢动物具有广谱驱避效果。我们的报告是鸟类体内存在内源性驱蚊剂的首个实证依据。
