ResumoThe thoracic spiracles were found to open synchronously in response to carbon dioxide or high temperature. At 25°C in a 20% carbon dioxide and air mixture, the opening of the spiracles was accompanied by a small depression of body temperature (of about 0·6°C). These spiracles opened fully at about 39–41°C and above this air temperature a depression of about 1·6°C was recorded. With all spiracles blocked the depression was much smaller and in moist air there was no depression. The conditions which, in the laboratory, were accompanied by spiracular opening may occasionally be comparable to the environment in the natural resting sites of the fly. The adaptive value of the mechanism is not proven, however.
