[Control of malaria vectors in tropical Africa (author's transl)].
Indoor spraying with residual insecticides is at present the most effective method of malaria control. Following the failures observed during the campaigns of malaria control using D.D.T., B.H.C. and dieldrin, the W.H.O. has undertaken a wide programme for evaluating and testing new insecticides. The principal compounds tested are discussed. Only four insecticides have been held back: malathion, propoxur, fenitrothion and dichlorvos. However this compounds are very expensive and less remanent than D.D.T.
