Maximum likelihood tree of partial COI sequences from Glossina sp. field samples. 563 bp stretches of 74 sequences were aligned and analysed as described under Methods to provide an overview of the population diversities in the different sampling sites. Tamura-3-parameter model with gamma distribution with the default setting for number of discrete gamma categories was used to construct the tree and evaluated with 800 bootstrap replicates. Sampling sites are indicated in brackets. Sequences with different positions than in the phylogenetic analysis shown in Fig. 2 are indicated. CAM Cameroon [32]
