Abstract:

The behavior of the thoracic spiracles of A. triseriatus and A. aegypti was observed in high 90 plus or minus 5 and low 5 relative humidities. Following a 5-minute exposure to low RH, spiracular responses to 1 2 carbon dioxide were reduced in both species, but only A. triseriatus showed attenuated spiracular behavior after a 2-minute exposure. Conservative spiracular opening was observed in both unfed and fed mosquitoes. It is postulated that the spiracular response to low RH is a sensory one.
