[Levels of resistance to insecticides and their mechanisms in 2 strains of Aedes aegypti from Panama].
The levels of susceptibility and/or resistance to insecticides in larvae and adults of Aedes aegypti from 2 localities of Panama (Rio Abajo and Victoriano Lorenzo) were determined. Among larvae, it was found resistance to methyl- pyrimifos in both localities; however, they were susceptible to the rest of the organophosphate insecticides (temephos, malathion, fenthion fenitrothion and clorpirifos) and to pyrethroids (deltamethrin, lambda-cyhalothrin, cypermethrin and cyfluthrin. In the trials carried out in adults, according to the categories of the World Health Organization, the 2 localities proved to be completely susceptible to deltamethrin, lambda-cyhalothrin, beta cypermethrin and cyfluthrin.
