通过在日落周围更快地殴打翅膀，雄性肛门蚊子将听觉系统感知到女性飞行音调。
在整个热带世界中，一群疟疾在日落中持续不到30分钟。检测系统：通过将其飞行调提高到女性的1.5倍，男性提高了女性的可听性，特别是在群中报道的“谐波收敛”事件。各种各样跨男性。
By beating their wings faster around sunset, male Anopheles mosquitoes sensitize their auditory system to female flight tones. Mating swarms of malaria mosquitoes form every day at sunset throughout the tropical world. They typically last less than 30 minutes. Activity must thus be highly synchronized between the sexes. Moreover, males must identify the few sporadically entering females by detecting the females’ faint flight tones. We show that the Anopheles circadian clock not only ensures a tight synchrony of male and female activity but also helps sharpen the males’ acoustic detection system: By raising their flight tones to 1.5 times the female flight tone, males enhance the audibility of females, specifically at swarm time. Previously reported “harmonic convergence” events are only a random by-product of the mosquitoes’ flight tone variance and not a signature of acoustic interaction between males and females. The flight tones of individual mosquitoes occupy narrow, partly non-overlapping frequency ranges, suggesting that the audibility of individual females varies across males.
