Effects of Flooding and Temperature on Aedes albifasciatus Development Time and Larval Density in Two Rain Pools at Buenos Aires University City
Aedes albifasciatus is a floodwater mosquito that breeds in temporary waters. This semi-domestic species, widely distributed in Argentina, is a competent vector of the western equine encephalitis. The present study was carried out in two rain pools of the city of Buenos Aires, from April 1998 throug...
