Fig. 2

Morphospace showing wing shape variation pattern of G. palpalis populations from Northern, Western, and Eastern Regions of Ghana. Morphospace is based on the first two Canonical Variates from discriminant analysis of wing shape variables. Convex hulls delimit extent of wing shape variations within population. Circular points represent individual tsetse flies. Tsetse flies of the same population are represented by same colour points. Squares within hulls represent average shape of a population. Overlapping of hulls representing populations from the Western (red) and Eastern (black) Regions indicates similarity in wing shape. Separation of hull representing population from the Northern Region (blue) signifies its dis-similarity in wing shape from the other populations
