A total of 52,033 sandflies, comprising 33 species, was collected in tree buttresses in Panama. Of the 18,025 females collected, 1,592 (8.8%) engorged phlebotomines of 18 species contained sufficient blood for identification of their vertebrate hosts by the microcapillary precipitin method. and , vectors of , had fed predominantly on sloths (47.0% and 65.1%, respectively). , a common non-anthropophilic sandfly in tree buttresses also fed most frequently on sloths (28.0%) and probably also contributes to the transmission cycle among the edentates. Two-toed sloths (), the principal reservoir of in Panama, cohabit the same arboreal bioptope with these sandfly species. was isolated in culture from 14 of 68 (20.6%) captured in the study sites during the period of this investigation. The data illustrate that the buttresses of large trees in Panama represent potential pathobiocenose bioptopes of . Other sandfly species tested for host-feeding sources included: , which fed preferentially on reptiles; , and fed most frequently on armadillos. The hosts of 11 additional sandfly species were identified; however, the numbers recorded were too small to discern distinct feeding patterns among these phlebotomines.
