[determination of insecticide resistance and its biochemical mechanisms in 2 strains of culex quinquefasciatus from santiago de cuba].	it was analyzed the behavior of the resistance of 3 organophosphated insecticides (malathion, clorpirifos and methyl-pyrimifos), 3 pyrethroids (deltamethrin, lambda-cyhalothrin and cypermethrin), and 1 carbamate (propuxur) in populations of culex quinquefasciatus from 2 municipalities of the province of santiago de cuba. the values of the resistance factor proved that there is resistance to malathion and clorpirifos. however, in spite of the existence of a high frequency of the mechanisms of ele ...	1997	9685989
[the ecological succession of mosquito species in the town of boyeros, ciudad de la habana 1994-1996].	an analysis was made on the incidence of culicidae in boyeros municipality, city of havana from 1994 to 1996 based on the requirements of the national program for eradication of aedes aegypti. a total of 13 species was detected in which aedes mediovittatus predominated during 3 years of study, followed by culex quinquefasciatus whereas for the first time aedes albopictus species was found in the territory. people's councils wajay, santiago de las vegas and armada exhibited the highest values of ...	2000	11107909
[determination of glutathione-s-transferase activity in culex quinquefaciatus strains in cuba and other latin american countries].	in the present paper, we standardized a microtitration assay for the determination of specific activity of glutathione-s-transferase using a culex quinquefasciatus strain selected in lab with pyrethroid insecticide lambdacyhalothrin for 6 generations (sp6). the saturation values for reduced glutathione and 1-chlorine 2,4-dinitrobenzene were 15 mm and 40 mm, respectively; we also estimated that 3 minutes was the optimal time in order to differentiate resistant strain sp6 from the susceptible refe ...	2004	15846907
