The eradication of <i>Glossina morsitans submorsitans</i> Newst. and <i>Glossina tachinoides</i> Westw. in part of a river flood plain in Northern Nigeria by chemical means. Part II.

Abstract

A stretch of river with its flood plain, a habitat of Glossina morsitans submorsitans Newst. and G. tachinoides Westw. in the Sudan savannah zone of Northern Nigeria, which is an important cattle-raising area, is described. An effective technique for the eradication of both species of tsetse has been developed, using a single application of a 5 per cent, aqueous suspension of DDT by knapsack sprayer in the places of dry-season concentration of the fly, and on the principal midday resting sites, viz ., between ground-level and a height of 5 ft. on tree trunks greater than 6 in. in diameter.
