Spiracular Responses of Aedes Mosquitoes to Carbon Dioxide and Oxygen
Annals of the Entomological Society of America
(1970)
Abstract
Observations were made on the responses of the thoracic spiracles of adult Aedes aegypti (L.), and adult A. triseriatus (Say) to a constant CO2 pressure in serial concentrations of O2 in N2 and to the O2 in N2 series alone. Less than atmospheric pressures of O2 caused an increase in the frequency and duration of spiracular opening. Higher than atmospheric O2 tensions had no effect on frequency of spiracular opening, but reduced the duration of opening. Carbon dioxide effected full spiracular opening in proportion to the O2 concentration. The duration of spiracular opening, regardless of amplitude, was also proportional to the ratio of CO2 to O2. Responses of Aedes spiracles to hypoxia and CO2 decreased with increasing duration of exposure.
