BISSET, Juan A.; RODRIGUEZ, María Magdalena  e  CACERES, Lorenzo. Niveles de resistencia a insecticidas y sus mecanismos en 2 cepas de Aedes aegypti de Panamá. Rev Cubana Med Trop [online]. 2003, vol.55, n.3, pp. 191-195. ISSN 1561-3054.

The levels of susceptibility and/or resistance to insecticides in larvae and adults of Aedes aegypti from 2 localities of Panamá (Río 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, b cypermethrin and cyfluthrin.
