The paper presents results of comparative studies of the level of sensitivity of endophilic malarial mosquito species to DDT and malathion. The sensitivity of the vectors was shown to remain at the same level in spite of cessation of DDT use in medical practice. It may be probably due to the use of organochlorines as pesticides within the city area. Wide use of organophosphorous preparations in medical and agricultural practices has not still led to malathion resistance.
