[A comparison of the level of resistance and irritability in Anopheles hyrcanus and An. superpictus to insecticides].

The resistance and irritability to malathion, fenitrothion, propoxur and DDT (WHO insecticide impregnated paper) were determined in the endophilic Anopheles superpictus population in Dushanbe and in the exophilic An. hyrcanus population in Parkhar district. An. superpictus proved to be completely susceptible to malathion, fenitrothion and propoxur, low resistant to DDT, and highly or moderately irritable to all the insecticides. On the contrary, An. hyrcanus, was low irritable to insecticides but highly resistant to DDT and moderately resistant to propoxur, while its susceptibility to malathion and fenitrothion remained complete. It is supposed that the nature of adaptation to insecticide pressure is, to a great extent, determined by mosquito endophily or exophily.
