[Studies of the sensitivity to the usual domestic insecticides on insects of the Anopheles maculipennis group, and Musca domestica, Cimex lectularius and Blattella germanica species].

The present paper was designed to the study of the degree of sensitivity of mosquitoes, flies, bedbugs and cockroaches to organochloride and organophosphoric insecticides produced in Romania. Testing of the sensitivity to insecticides of these species, important as transmitters of human pathogens, showed the effectiveness of the products, which induced a high mortality rate in relatively small concentrations. Against Anopheles labranchiae atroparvus, the insecticides Detox, Carbetox and Lindatox proved efficient in concentrations of 1.0%, 0.5% and 1.0% respectively. Against Musca domestica Lindatox and Detox proved efficient in 1.0% concentration. Cimex lectularius responded with a mortality rate of 100% to 0.5% Lindatox, 1.5% Plotox and 1.0% Dipterex. Against Blattela germanica, 100% mortality was obtained after one hour exposure to Lindatox, Detox and Carbetox in 1.0% concentration, to 3.3% Plotox and 1% Piretrin.
