Figure 5.

Neighbor-joining tree of infected black flies based on cox1 gene sequences. Bootstrap values and posterior probabilities (NJ/ML/BI) are shown above or near the branches. A dash indicates that support values are less than 50% (for NJ and ML) or 0.50 (for BI). The scale bar represents 0.02 substitutions per nucleotide position. Red triangles, blue circles, green squares, and black stars before each specimen designate the specimens obtained from this study and also indicate the species/group of nematode larvae recovered.
