The attraction of female mosquitoes (Anopheles quadrimaculatus Say) to stored human emanations in conjunction with adjusted levels of relative humidity, temperature, and carbon dioxide

Abstract

An apparatus has been assembled which permits storage and injection, at the same flow rate, of air containing human emanations into one port and air containing no emanations into the other port of a dual-port olfactometer, while monitoring the two flows for differences in temperature, relative humidity, and carbon dioxide level. Results of bioassays so conducted have led us to conclude that female mosquitoes (Anopheles quadrimaculatus Say) are attracted in significant numbers primarily by chemical emanations other than carbon dioxide and water.
