The influence of temperature and r.h. on the flight performance of tethered virgin female Aedes aegypti was investigated. Mosquitoes of similar age were flown to exhaustion on flight mills at various temperatures and relative humidities. Parameters measured were distance flown, duration of flight, speed of flight, initial weight of mosquitoes, and live weight lost during exhaustive flight. The temperature range at which sustained tethered flight occurred was 15 to 32C. Temperature extremes at which flight was possible were 10 and 35C; however, performance was minimal in both duration and distance at these temperatures. The optimal temperature for flight was 21C. Mosquitoes flew farther at 15C than at the commonly reported optimal temperature of 27C. In general, flight performance was greater below 27C. Relative humidity within 30 to 90 per cent had no demonstrable influence on flight performance at any temperature studied except at 32C, where 30 per cent had a marked limiting effect on mosquito flight.
