The control of mosquito transmitted diseases such as malaria, dengue fever, and Chikungunya is still largely dependent on mosquito population control. Unfortunately, many of the tools we use to control mosquito populations are currently threatened by the evolution of insecticide resistance. Researchers are developing new strategies to manage mosquito populations. Several new promising strategies involve genetic or reproductive control. In these cases, males will be mass reared in the laboratory and released into nature where they will need to compete with wild males for mates. These males will deliver technologies that will either reduce the mosquito population or the population's ability to transmit disease. Unfortunately, we know very little about mosquito mating behaviour. Specifically, we do not know what makes a male attractive to females. In this project, we propose to investigate newly discovered acoustic signals to determine if we can use male signalling ability to accurately predict how laboratory reared males will perform in competition with wild males. So far we know that the presence of a convergence event it important for female choice, but we do not know which components of the signal she is paying attention to. First, we will measure signal components such as latency, rate, range, and consistency while recording mating interactions between live mosquitoes to determine which are most predictive of male mating success. Males used in releases will need to be reared in the laboratory. Thus, understanding how rearing practices influence male courtship signals is important. However, the role of environment in shaping these signals has not been investigated. We will use artificial playbacks to measure the signalling performance of males that have been subjected to various laboratory conditions. Finally, we will use this new knowledge to determine if harmonic convergence signalling ability is a predictor of how males will perform under field conditions. We will test males with low or high signalling performance against wild males in large field cages. This will allow us to test if acoustic measurement could be used as a high-throughput assay to males in rearing programs. At the conclusion of this project, we will have advanced our understanding of sexual selection in mosquitoes and developed a new tool for control programs.

蚊子传播疾病如疟疾、登革热和基孔肯雅热的控制仍然主要依赖于蚊子种群控制。不幸的是，我们用来控制蚊子种群的许多工具目前正受到杀虫剂耐药性演变的威胁。研究人员正在开发新的策略来管理蚊子种群。一些新的有希望的策略涉及遗传或生殖控制。在这些情况下，雄性将在实验室中大规模饲养，并释放到大自然中，在那里它们需要与野生雄性竞争配偶。这些雄性将提供技术，减少蚊子数量或减少蚊子传播疾病的能力。不幸的是，我们对蚊子的交配行为知之甚少。具体来说，我们不知道是什么让男性对女性有吸引力。在这个项目中，我们建议调查新发现的声音信号，以确定我们是否可以使用男性信号的能力，以准确地预测实验室饲养的男性将如何执行与野生男性的竞争。到目前为止，我们知道收敛事件的存在对女性的选择很重要，但我们不知道她关注的是信号的哪些组成部分。首先，我们将测量信号成分，如延迟，速率，范围和一致性，同时记录活蚊子之间的交配相互作用，以确定哪些最能预测雄性交配成功。用于释放的雄性需要在实验室饲养。因此，了解养育方式如何影响雄性求偶信号是很重要的。然而，环境在塑造这些信号中的作用尚未被研究。我们将使用人工回放来测量已受到各种实验室条件下的男性的信号性能。最后，我们将使用这一新的知识，以确定谐波收敛信号的能力是一个预测如何男性将在现场条件下执行。我们将测试男性低或高信号性能对野生男性在大型领域的笼子里。这将使我们能够测试声学测量是否可以用作饲养计划中雄性的高通量测定。在这个项目结束时，我们将进一步了解蚊子的性选择，并开发出一种新的控制程序的工具。
