Preliminary evalution of a black cylinder suction trap for Aedes aegyptia and Culex quinquefasciatus (Diptera: Culicidae)

The response of A. aegyptia 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 A. aegypti trap. In a series of trials, the cylinder trap caught only 1/3 as many female A. aegypti but took twice as many males as the Fay trap. Unexpectedly, both traps caught significant numbers of C. quinquefasciatus . The black cylinder took 1.5x as many males and 1.8x as many females as the Fay trap. Gravid, nulliparous, engorged, and parous specimens were represented in the catches.
