Salivary protein profiles distinguish triatomine species and populations of Triatoma dimidiata (Hemiptera: Reduviidae).
Seven Triatoma dimidiata (Latreille, 1811) populations from different provinces of Guatemala were compared along with three related triatomine species using the electrophoretic profiles of salivary proteins. The analysis of salivary proteins allowed the separation of two of the species into their respective complexes, phyllosoma (T. pallidipennis) and protracta (T. nitida) (Lent and Wygodzinsky, 1979), whereas T. dimidiata seems slightly separated from either of these. Based on salivary protein profiles, T. dimidiata is most closely related to the cluster including T ryckmani and T. nitida (protracta) and more diverged from T. pallidipennis (phyllosoma). Among Guatemalan T. dimidiata populations, the cave population from Lanquin is separated from the rest of populations analyzed, suggesting that it is in the process of speciation. No difference in protein banding pattern was observed among populations from domestic and peridomestic ecotopes from the same region.
