Preliminary Evaluation of a Black Cylinder Suction Trap for Aedes Aegypti and Culex Quinquefasciatus (Diptera: Culicidae)1

Abstract

The response of Aedes aegypti to an experimental glossy black cylindrical suction trap was evaluated in a series of 30-min tests under controlled conditions. Maximum mean capture rates of 60 and 90% were observed for males and females, respectively. These results suggested a field comparison with the Fay Aedes aegypti trap. In a series of trials, the cylinder trap caught only 1/3 as many female Ae. aegypti but took twice as many males as the Fay trap. Unexpectedly, both traps caught significant numbers of Culex quinquefasciatus. The black cylinder took 1.5 x as many males and 1.8 x as many females as the Fay trap. Gravid, nulliparous, engorged, and parous specimens were represented in the catches.
