title: [The level and nature of insecticide resistance (DDT and malathion) in laboratory-strain mosquitoes].
abstract: Authors characterize 7 mosquito strains and species from the collection of the E. I. Martsinovskiĭ Inst. with regard to the levels and mechanisms of their resistance to malathion and DDT. Resistance mechanisms of the strains An. stephensi, An. sacharovi, An. atroparvus, Ae. aegypti and C. pipiens were determined with the help of synergists. Malathion-resistance in one of the An. stephensi strains is due to high carboxyl activity. Other strains featured various levels of DDT-resistance due to various mechanisms: in Ae. aegypti it was due to mixed-function oxidases activity; in An. atroparvus, An. sacharovi and An. stephensi second strain to glutathione-dependent transferase, in C. pipiens, An stephensi third strain and, partially, An. sacharovi,--to the probable presence of kdr-factor.
