In the present investigation, speed of mosquitoes A. aegyptii (Linnè) and Culex quinquefasciatus (Say) is measured by designing and constructing a low speed wind tunnel in the laboratory. The velocity of mosquitoes is less than the other myogenic and neurogenic insects. Lift, one of the important aerodynamic forces that a flier has to develop for its efficient flight, is studied in mosquitoes by developing a simple technique using digital single pan balance. Lift, drag and their coefficients of hovering mosquito are calculated from the knowledge of body parameters by considering the wings of mosquito as harmonic oscillator. The calculated value of lift is verified with the experimental. The study throws light on morphophysiological adaptation of mosquitoes for the generation of aerodynamic forces in hovering, tethered and forward flights.
