| [prevalence of microbiota in the digestive tract of wild females of lutzomyia longipalpis lutz & neiva, 1912) (diptera: psychodidae)]. | we dissected the digestive tract of 245 females in pools of 35 flies forming 7 groups. these flies were lutzomyia longipalpis originating from lapinha cave, lagoa santa, minas gerais. out of the 8 species of bacteria isolated there was a predominancy of gram negative bacterias (gnb) in the group of non-fermenters of sugar belonging to the following species: acinetobacter lwoffii, stenotrophomonas maltophilia, pseudomonas putida and flavimonas orizihabitans. the group of gnb fermenters were: ente ... | 2000 | 10967602 |
| studies on populations of lutzomyia longipalpis (lutz & neiva, 1912) (diptera: psychodidae: phlebotominae) in brazil. | studies were performed on five brazilian populations of lutzomyia longipalpis: salvaterra (pa), são josé do ribamar (ma), canindé (ce), natal (rn) and gruta da lapinha, lagoa santa (mg). no morphological differences were observed that could distinguish between these populations. homogeneity tests showed that the allopatric populations display a certain heterogeneity and that the sympatric populations, with different patterns of spots, are homogeneous. the student-newman-keuls test, represented b ... | 2000 | 10800188 |
