Resumen
RODRIGUEZ, María Magdalena; BISSET, Juan; DIAZ, Cristina y SOCA, Alain. Selección de una cepa de Culex quinquefasciatus resistente a lambdacialotrina y su espectro de resistencia cruzada a otros insecticidas. Rev Cubana Med Trop [online]. 1998, vol.50, n.2, pp. 129-132. ISSN 1561-3054.
A field strain of Culex quinquefasciatus resistant to pyrethroid lambda-cyhalothrin insecticide was selected to be used as a reference strain in the laboratory for conducting studies of biochemistry and genetics of resistance, to evaluate the utility of this insecticide for the control of mosquitoes in Cuba, and to determine the cross resistance to organophosphate insecticides, pyrethroids and a carbamate. A hig resistance to lambdacyhalothrin was obtained after 6 generations of selective pressure. Lowe or no cross resistance to other pyrethroids (deltamethrin and cyper-methrin), to a carbamate (propoxur) and to the organophosphate insecticides (clorpirifos and methyl-pyrimifos) was observed. A high cross resistance to malathion (organophosphate) was detected.
