Impact of underground storm drain systems on larval ecology of Culex and Aedes species in urban environments of Southern California

Abstract An extensive network of storm water conveyance systems in urban areas, often referred to as the “underground storm drain system” (USDS), serves as significant production habitats for mosquitoes. Knowledge of whether USDS habitats are suitable for newly introduced dengue vectors Aedes aegypt...
