ield studies were conducted in the Upper Rhine Valley to determine the responses of mosquitoes to CDC traps baited with either CO 2 , octenol, light or paired combinations of these. Among eight mosquito species caught, the attractant effect on trap catches was studied in the four most abundant: Aedes vexans, Ae.rossicus, Ae.cinereus and Culex pipiens . Traps baited only with light or octenol caught few mosquitoes, whereas many were caught by traps baited with CO 2 alone or in combination with either of the other candidate attractants. CO 2 baited traps, with or without light, caught the most Aedes . The combination of CO 2 and octenol attracted most Cx pipiens , but this apparent synergy was not significant. Using a caged hamster compared to CO 2 as bait in a CDC light‐trap with only intermittent fan suction, the hamster attracted less mosquitoes than CO 2 emitted at a rate of 225 g/h on days 1 and 2, whereas on days 3 and 4 the smell from the hamster's cage became significantly more attractive than this rate of CO 2 for all species of mosquitoes.
