化学通讯是最古老和最广泛的通讯形式。然而，我们才刚刚开始理解化学信号的复杂性及其在性选择中的作用。本文以昆虫为研究对象，综述了嗅觉性别选择研究的最新进展。我们将展示，有越来越多的经验证据表明，性选择影响化学性状的进化，但选择的形式和强度在物种之间存在差异。研究表明，某些化学信号的表达与个人的状况有关，并取决于年龄、免疫能力、生育能力、体型或近亲繁殖的程度等。男性或女性可能会受益于选择基于这些特征，获得资源或“好基因”。其他化学性状似乎可靠地反映了一个人的潜在基因型，并适合选择最匹配自己的基因型的交配伴侣。
Chemical communication is the most ancient and widespread form of communication. Yet we are only beginning to grasp the complexity of chemical signals and the role they play in sexual selection. Focusing on insects, we review here the recent progress in the field of olfactory-based sexual selection. We will show that there is mounting empirical evidence that sexual selection affects the evolution of chemical traits, but form and strength of selection differ between species. Studies indicate that some chemical signals are expressed in relation to an individual’s condition and depend, for example, on age, immunocompetence, fertility, body size or degree of inbreeding. Males or females might benefit by choosing based on those traits, gaining resources or “good genes”. Other chemical traits appear to reliably reflect an individual’s underlying genotype and are suitable to choose a mating partner that matches best the own genotype.
