Aedes aegypti, Aedes albopictus, and dengue in Argentina: current knowledge and future directions
Current resistance status to temephos in Aedes aegypti from different regions of Argentina
In Argentina, more than 25,000 cases of dengue were reported in the
summer of 2009, even in provinces where the disease was formerly
absent. We analysed the susceptibility levels to the larvicide temephos
in seven populations of Aedes aegypti , the primary vector of dengue,
collected during summer 2007/2008, using the susceptible Rockefeller
strain as a control. Although no control failures were observed during
the experiment, a majority of the lethal concentration and resistance
ratio values indicate an incipient resistance. An integrative program
to monitor the resistance of Ae. aegypti to insecticides is needed in
the country
