Resumo: A synthetic blend of chemicals comprising volatiles released by the human body has been shown to be an effective attractant for female Aedes aegypti in olfactometer bioassays with laboratory-reared mosquitoes. We report the laboratory evaluation of Ae. aegypti response to a synthetic blend tested with 4 types of mosquito traps (CDC model 512, CDC model 1012, CFG, and Fay Prince traps). Aedes aegypti females were attracted significantly by the blend. The higher release rate of attractant (320.2 +/- 10.71 mg/h) more efficiently attracted mosquitoes than the lower release rate (42.0 +/- 2.3 mg/h). Although both the Fay-Prince and CFG traps caught higher number of mosquitoes than the other traps, only the CFG trap caught a statistically significant greater number of mosquitoes. The results suggest that the synthetic blend is effective in attracting Ae. aegypti females under controlled laboratory conditions (i.e., a closed system). Further studies are needed to evaluate the efficacy of this blend in baited traps under field conditions.
