Sexual selection theory meets disease vector control: Testing harmonic convergence as a "good genes" signal in Aedes aegypti mosquitoes.

Background: The mosquito Aedes aegypti is a medically important, globally distributed vector of the viruses that cause dengue, yellow fever, chikungunya, and Zika. Although reproduction and mate choice are key components of vector population dynamics and control, our understanding of the mechanisms of sexual selection in mosquitoes remains poor. In "good genes" models of sexual selection, females use male cues as an indicator of both mate and offspring genetic quality.

Male accessory gland molecules inhibit harmonic convergence in the mosquito Aedes aegypti.

Aedes aegypti mosquitoes transmit pathogens such as yellow fever, dengue, Zika, and chikungunya viruses to millions of human hosts annually [1]. As such, understanding Ae. aegypti courtship and mating biology could prove crucial to the success of disease control efforts that target reproduction.
