雄蚊通过约翰斯顿器官（JO）的飞行音调来探测和定位同种雌蚊，约翰斯顿器官在局部粒子运动的影响下探测触角偏转。蚊子的声学行为及其JO生理在频域内得到了广泛的研究，但雄性蚊子在音致性飞行开始时的听觉范围和行为尚不清楚。在这项研究中，我们通过整合雄性JO的生理调谐响应和来自数值模拟的雌性气动声学特征，预测了飞行的致倦库蚊的最大空间感觉包络。我们的感官包络预测通过自由飞行的雄性对雌性人工纯音的反应进行了行为测试。在飞行试验中观测到的最小可探测粒子速度与我们在以前的研究中测量到的峰值JO灵敏度形成的理论预测很好地吻合。描述最小可检测粒子速度的等面代表了雄性的定量听觉范围，并且相对于雌性的身体方向是定向的。我们的研究结果阐明了交配行为的复杂性，并指出了观察飞行蚊子的身体取向对于充分理解同种交流的感觉生态学的重要性。
Male mosquitoes detect and localize conspecific females by their flight-tones using the Johnston's organ (JO), which detects antennal deflections under the influence of local particle motion. Acoustic behaviours of mosquitoes and their JO physiology have been investigated extensively within the frequency domain, yet the auditory sensory range and the behaviour of males at the initiation of phonotactic flights are not well known. In this study, we predict a maximum spatial sensory envelope for flying Culex quinquefasciatus by integrating the physiological tuning response of the male JO with female aeroacoustic signatures derived from numerical simulations. Our sensory envelope predictions were tested with a behavioural assay of free-flying males responding to a female-like artificial pure tone. The minimum detectable particle velocity observed during flight tests was in good agreement with our theoretical prediction formed by the peak JO sensitivity measured in previous studies. The iso-surface describing the minimal detectable particle velocity represents the quantitative auditory sensory range of males and is directional with respect to the female body orientation. Our results illuminate the intricacy of the mating behaviour and point to the importance of observing the body orientation of flying mosquitoes to understand fully the sensory ecology of conspecific communication.
