Abstract

Há poucos estudos sobre a microbiota do trato digestivo de flebotomíneos, considerando-se que o sangue não é o único alimento ingerido. Os flebotomíneos, tanto os machos como as fêmeas, alimentam-se de açúcares, provenientes de várias fontes, possibilitando a ingestão de microrganismos. As chances de contaminação aumentam nos insetos criados em laboratório e pode interferir no desenvolvimento da Leishmania spp. Foi separado um total de 300 fêmeas, divididas em dois lotes, das quais extraímos o trato digestivo. No lote 1(fêmeas alimentadas com sangue e sacarose) das 10 espécies bacterianas isoladas, a família Enterobacteriaceae esteve representada pelos gêneros Serratia, Enterobacter e Yokenella, e o grupo dos não fermentadores pelos gêneros Pseudomonas, Acinetobacter e Stenotrophomonas. No lote 2 (fêmeas alimentadas apenas com sangue) das 8 espécies isoladas o grupo dos não fermentadores esteve representado pelos gêneros Acinetobacter, Stenotrophomonas, Burkolderia e Pseudomonas, e a família Enterobacteriaceae, pelos gêneros Enterobacter e Serratia.

Abstract

Males of cryptic or closely related species present great morphological variation in their genitalia, whereas females, such as those of the Chagasi Series of the PsychodopygusMangabeira, 1941 genus, are more similar. Therefore, our aim was to study the fine structure of the male genitalia of five species of the Chagasi Series to better understand the variation in their morphology and its influence on the copulatory process. The sand fly species were captured in the following Brazilian states: Psychodopygus chagasi(Costa Lima, 1941) (Rondônia), Psychodopygus complexus(Mangabeira, 1941) (Tocantins), Psychodopygus squamiventris maripaensis(Floch & Abonnenc, 1946) (Amapá), Psychodopygus squamiventris squamiventris(Lutz & Neiva, 1912) (Amazonas), and Psychodopygus wellcomeiFraiha, Shaw & Lainson, 1971 (Pará and Ceará). Insects were stored in ethanol 70% (then dehydrated) and dry after they were sputtered with gold. The samples were observed under a scanning electron microscope. Microtrichiae, two types of trichoid sensilla, coeloconic and chaetic sensillae, were observed on the antenna of all species, with no difference between them. Only on the anepimeron of P. squamiventris squamiventrisa modified ‘racket’-like scale was observed. As for the male genitalia, the setae and structures of each species were fully described, such as the small setae on the paramere apex of the P. squamiventrissubspecies, and the grooves present in this region and on the paramere lobe of P. complexusand P. wellcomei, which are impossible to observe with optic microscopy. New information is thus provided on the male genitalia, which can contribute to future bionomic studies of these species.
