Sensory Effects of Relative Humidity on Thoracic Spiracles of Aedes Mosquitoes

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.
