Report of the Distribution of Tsetse-flies in the Neighbourhood of Accra

Abstract

The results of the investigation may be summarised as follows: Two species of Glossina were encountered in the neighbourhood of Accra, namely, G.palpalis, R.-D., and G. longipalpis, Wied. They were found all along the range of hills to the west and north of the Accra plain, and extending thence a little way on to the plain, G. longipalpis spreading rather farther than G. palpalis. The greater part of the plain was found to be free from tsetse-flies and unsuitable for them. In the town of Accra itself no tsetse-flies were found, and although it is well known that occasional specimens reach it (probably being transported thither by motor vehicles and railway trains), no evidence was obtained that they had established themselves there or would be able to do so under existing conditions.
