Acoustotactic response of mosquitoes in untethered flight to incidental sound

Abstract Mosquitoes are vectors for some of the most devastating diseases on the planet. Given the centrality of acoustic sensing in the precopulatory behavior of these vectors, the use of an exogenous acoustic stimulus offers the potential of interfering with the courtship behavior of these insects...

Previous research on the acoustotactic response of mosquitoes has been conducted on tethered preparations using low-intensity sound stimuli.

The data show, for the first time, significant sex- and species-specific differences in acoustotactic responses. A. aegypti exhibited a greater response to sound stimulus compared to An. gambiae, and the response also extended over a larger range of frequencies.
