[Experimental studies of the control of mosquitoes of the genus Anopheles using selected insecticides]

In the research 4 compounds: Iodofenphos, Propetamphos, Dioxacarb and Permethrin and two commercial insecticides: Pibutoks Super (Permethrin) and Safrotin 10 WP (Propetamphos) were used to control anophelini females. The chemicals were tested in the laboratory on mosquitoes caught in the nature and the contact method was employed. Propetamphos and Permethrin at concentrations 0.05% and 0.1%, after 2 hours of 1 hour exposure reduced the mosquitoes in 96% and 99.9% respectively. Iodofenphos and Dioxacarb, even at concentration 0.1%, after 24 hours of 1 hour exposure caused barely 78.3% and 83.9% mortality of these insects. Both insecticides tested, in the 7 days period after the spraying, caused more than 97% reduction of the Anopheles population in the cow-sheds.
