Adult mosquito surveillance is the backbone for all integrated mosquito management programs, as these data collected is used to analyze trends in vector mosquito populations, the prevalence of arboviruses such as Eastern equine encephalitis, Jamestown Canyon virus, and West Nile virus. Essentially, adult mosquito surveillance is about gathering data to make informed decisions for effective mosquito management and protecting public health.
To track adult mosquitoes and arboviruses in the area, PVMCD staff will deploy over 400 specialized adult mosquito surveillance traps across 212 trap sites.
There are two distinct types of traps that are primarily used by the District:
CDC Miniature Light Trap: This trap is baited with carbon dioxide (CO2) and designed to attract a variety of mammal-biting mosquitoes. The use of CO2 mimics the exhalation of mammals, making a very effective tool for attracting mosquitoes seeking blood-meals. CDC Miniature light traps can also be baited with Octenol, a chemical that is used to attract Aedes albopictus mosquitoes.
Gravid Trap: Characterized by its unappealing aroma, the gravid trap is baited with hay-infused water. This unpleasant scent is specifically attractive to Culex pipiens and restuans mosquitoes, which are considered primary vectors in the spread of WNV.
