Tests carried out since 1974 in the field and the laboratory with Anopheles sacharovi Favr, A. hyrcanus (Pall.) and A. maculipennis Mg. from Turkey showed that resistance to organophosphorus and carbamate insecticides has developed in all 3 species, in the first 2 in the southern Chukurova plain and in the third in the northern area around Osmanjik. Resistance was indicated by the failure of supposed lethal doses to kill significant proportions of the anopheline populations. The temperature at which the tests were carried out had a marked influence on the level of mortality obtained. Broad spectra of resistance were shown by all 3 species, though with interspecific differences; they are attributed to the extensive and intensive use of a wide range of chemicals for agricultural pest control. Of the insecticides readily available for house-spraying for malaria control, malathion appears to be the one with the greatest potential usefulness.
