Abstract: | A means of contaminating tsetse flies in the field with fluorescent pigment powders has been developed, using pigment in open-ended plastic chambers at the cage position on traps. Glossina pallidipes Austen and G.morsitans morsitans Westwood passed rapidly through the chambers, and on exit were contaminated with consistent doses of powder: about 90 micrograms/fly when powder was presented on the chamber roof and about 28 micrograms/fly when powder was presented on the chamber floor. The technique automatically marks tsetse flies with pigment, cheaply, simply and with the minimum imposition of stress and is expected to be particularly useful in ecological studies. Its potential for marking other biting flies is discussed. |
