title: Distribution of Simulium yahense after larviciding activities in the southern extension of the Onchocerciasis Control Programme.
abstract: The distribution range of Simulium yahense in the Eastern Operational Area of the Onchocerciasis Control Programme increased after larviciding treatments were started in 1988, to control important Simulium damnosum s. 1. vectors of onchocerciasis. A distribution map indicating the extended range is drawn and the importance of this expansion of S. yahense to disease transmission discussed.
