在求爱期间，男性经常向女性传达有关其健康状况的信息。最近描述了在男女上的飞行蚊子或谐波收敛的谐波成分。这种行为发生在交配之前，并已建议在伴侣选择中起作用。我们调查了谐波融合是蚊子求爱的组成部分的假设。该假设的关键预测是，谐波收敛应向潜在的有关健身益处的伴侣提供信息。我们测量了谐波收敛行为对女性获得的直接和间接益处的影响。我们发现，在交配之前以谐波频率汇聚的对儿子的交配成功增加了，并且这些后代本身更有可能在交配之前融合。这些结果表明，男性可能能够在交配之前向女性发出有关其遗传质量的信息，并且该信号可能是可遗传的。这些发现对于我们对蚊子行为的理解很重要，并在控制蚊子传播疾病中应用。这项研究还有助于研究男女相互作用和信号进化。
During courtship males often communicate information about their fitness to females. The matching of harmonic components of flight tone in male-female pairs of flying mosquitoes, or harmonic convergence, was recently described. This behaviour occurs prior to mating and has been suggested to function in mate selection. We investigated the hypothesis that harmonic convergence is a component of mosquito courtship. A key prediction of this hypothesis is that harmonic convergence should provide information to potential mates about fitness benefits. We measured the effect of harmonic convergence behaviour on the direct and indirect benefits obtained by females. We found that the sons of pairs that converged at harmonic frequencies prior to mating had increased mating success and that these offspring were themselves more likely to converge prior to mating. These results suggest that males may be able to signal information about their genetic quality to females prior to mating and that this signal may be heritable. These findings are important for our understanding of mosquito behaviour and have applications in the control of mosquito-borne disease. This study also contributes to the study of male-female interactions and signal coevolution.
