Phylogenetic tree of the T. dimidiata salivary lipocalins with those from other triatomine bugs. The sequences of T. dimidiata lipocalin obtained in the present study were aligned with representative triatomine lipocalin sequences obtained from the non-redundant protein database, and a phylogenetic tree was constructed. The sequences from the database are represented by “GenBank accession number (abbreviation of the species name)”. T.in, T. infestans; T.br, T. brasiliensis; T.pa, T. pallidipennis; T.pr, T. protracta; R.pr, R. prolixus. The scale bar represents 0.2% divergence.
