Bayesian phylogenetic trees of DWV isolates based on a 434 nt region encoding viral structural proteins. (A) Bayesian phylogenetic trees of DWV isolates from V. destructor infested honey bee pupae (VD_B) and matched mites (VD_M), and (B) T. mercedesae infested honey bee pupae (TM_B) and mites (TM_M), were constructed based on partial VP2 and VP1, and full VP4 sequences. Cases in which a pupa and infesting mites were infected by an identical single DWV variant are indicated as either VD_BM or TM_BM. Posterior probabilities are shown at the corresponding node of each branch. DWV type A, B, and C strains (with red letter) were included for analysis as references and SBV (Sac brood virus) with blue letter was used as an outgroup.
