Abstract
A general account is given of insecticidal control of black-flies in North and Central America, and the problems are contrasted with those arising in the control of Simulium damnosum Theo. in Nigeria. Some recent biological observations on Canadian black-flies are described, and it is emphasized that these have materially contributed to successful control. It is pointed out that S. damnosum control is being practised in the absence of much fundamental biological knowledge of this pest. Entomological aspects of onchocerciasis in Mexico and Guatemala are discussed, and compared with S. damnosum and its relationship to onchocerciasis in Nigeria.
