  abstract = {{M}osquitoes of many species mate in station-keeping swarms. {M}ating chases ensue as soon as a male detects the flight tones of a female with his auditory organs. {P}revious studies of hearing thresholds have mainly used electrophysiological methods that prevent the mosquito from flying naturally. {T}he main aim of this study was to quantify behaviourally the sound level threshold at which males can hear females. {F}ree-flying male {A}nopheles coluzzii were released in a large arena (similar to 2 m highx2 mx1 m) with a conspicuous object on the ground that stimulated swarming behaviour. {M}ales were exposed to a range of natural and synthetic played-back sounds of female flight. {W}e monitored the responses of males and their distance to the speaker by recording changes in their wing beat frequency and angular speed. {W}e show that the mean male behavioural threshold of particle velocity hearing lies between 13 and 20 d{B} sound particle velocity level ({SVL}) (95% confidence interval). {A} conservative estimate of 20 d{B} {SVL} (i.e. <0.5 mu m s(-1) particle velocity) is 12-26 d{B} lower than most of the published electrophysiological measurements from the {J}ohnston's organ. {I}n addition, we suggest that (1) the first harmonic of a female's flight sound is sufficient for males to detect her presence, (2) males respond with a greater amplitude to single-female sounds than to the sound of a group of females and (3) the response of males to the playback of the flight sound of a live female is the same as to that of a recorded sound of constant frequency and amplitude.},
