Evaluation of Aedes Aegypti Presence and Abundance in Septic Tanks and Their Impacts on Dengue Transmission

摘要

Aedes aegypti is the mosquito vector for dengue fever and has historically been considered to prefer 'clean' water for development. A 2006 study by the Centers for Disease Control and Prevention (CDC) demonstrated large numbers of adult Ae. aegypti mosquitoes emerging from septic tanks in Puerto Rico. The purposes of this study were (1) to definitively document larval presence in septic tanks and evaluate the water properties and environmental factors related to that presence, (2) examine the use of 2,2- dichlorovinyl dimethyl phosphate impregnated strips for control of mosquito productivity in septic tanks, and (3) use Geographic Information Systems to examine the association between the presence of septic tanks and other environmental factors and the incidence of dengue in Puerto Rico.
