Instraspecific variations of wing and thorax size of <em>Glossina palpalis palpalis</em> (Robineau-Desvoidy, 1830) in the forest region of Côte d'Ivoire

Abstract

Thorax and wing morphometry was studied in 497 Glossina palpalis palpalis caught on the outskirts of a village in the center-west of Côte d’Ivoire. Significant size differences were observed depending on the sex and season of catching. Tsetse flies caught at the end of the rainy season were bigger than those caught during the dry season. Within a G. p. palpalis population, the relation between climatic conditions and a fly might affect the latter’s vectorial capacity. New analytical methods in size measurement will help further specify these results.
