Abstract
The structure of the Phlebotomine sand fly community from the Venezuelan Andes was studied using null-model tests. The analyses, at the living zones and altitudes scales, revealed C-scores larger than those expected by random, independently of the collection technique ( P < 0.05). These results imply that sand fly species are non-aggregated at both scales. Random results for the variance of C-score and for the favored states hypothesis suggest that sand fly species belong to an unique guild. The latter is reinforced by the fact that anthropophilic and zoophilic species use in the same way a common resource (blood). Finally, we suggest additional approaches to study the role of the sand fly community structure on the genesis and dynamics of transmission of American cutaneous leishmaniasis.
