Autocidal Gravid Ovitrap Incorporation with Attractants for Control of Gravid and Host-Seeking Aedes aegypti (Diptera: Culicidae)

Aedes aegypti Linnaeus (Diptera: Culicidae) is a primary vector of multiple arboviruses including Zika, dengue, chikungunya, and yellow fever. After incorporating BG lure or BG lure + octenol, the CDC's Autocidal Gravid Ovitrap (AGO) was more effective at collecting and controlling host-seeking female Ae. aegypti than gravid female mosquitoes. The addition of octenol to the AGO did not increase the number of female mosquitoes captured by the AGO, compared with the AGO alone. The AGO baited with the BG lure captured a significant number of host-seeking female Ae. aegypti. This finding indicates that the combination of AGO with BG lure could enable the trap to control female Ae. aegypti mosquitoes representing either host-seeking or gravid physiological states.
