Summary
Researchers found that disrupting the male-specific isoform of the fruitless gene (fruM) in Aedes aegypti completely abolishes sound attraction behaviors in males, preventing them from locating females for mating. Mutant males showed severely reduced ability to amplify female flight sounds and transmitted sound-evoked electrical signals at about one-sixth the magnitude of controls. The study demonstrates that FruM controls male-specific hearing functions underlying mating behavior.
