Factors that may Influence the Infection Rate of Glossina Palpalis with Trypanosoma Gambiense: I.—The Age of the Fly at the Time of the Infected Feed.

Abstract

Much experimental work on the polymorphic trypanosomes has been hindered by the low percentage of flies that become infected. The conditions necessary for the infection of the fly and the factors which may increase the infection rate have been studied by several workers, but the published evidence is often conflicting.
