Since 2003 some Arizona counties have followed mosquito surveillance protocols to trap the West Nile Virus vector, Culex spp., using CO2 traps. Despite low sensitivity of these traps to detect Aedes spp., one out of seven CO2 traps deployed in Santa Cruz County detected Aedes aegypti in 2014. Enhancing surveillance for Aedes spp. in this region is critical, given that local transmission of dengue has occured across the border in Nogales, Sonora. Limited resources in Santa Cruz County have previously inhibited efforts to enhance mosquito surveillance . To broaden the reach of county surveillance, we implemented a community participatory project by engaging residents to conduct ovitrapping, a non-technical trap that attracts Aedes spp.
Objective
The objective of this work is to develop an efficient communitybased strategy to enhance mosquito surveillance for Aedes spp., vector for chikungunya and dengue viruses, in Santa Cruz County on the U.S.-Mexico border. We aim to determine vector presence, distribution, and seasonality by using ovitraps maintained by community members.
