Análise documental da diversidade de flebotomíneos (Diptera, Psychodidae) do município de Lagoa Seca, PB.

Abstract

Phlebotomines (Diptera: Psychodidae) make up a group, important for Medical Parasitology, of blood spatters and natural vectors of Leishmaniasis. The objective of this work was to analyze the diversity of Phlebotomines species in the city of Lagoa Seca-PB. A retrospective documentary research was done, using secondary data recorded in the Environmental Health Surveillance sector of the Lagoa Seca Municipal Secretary, for the years 2008-2017. The entomological surveys conducted in the field by the Endemic Agents staff were analyzed as part of the Leishmaniasis Surveillance and Control Program. The selected Phlebotomines were identified at the Entomology Laboratory and at FUNASA, Campina Grande. In the period 2008-2017, 410 specimens of Phlebotomines were captured, of which 268 were not identified among the years 2008 and 2011 (65.4%). In 2017, 142 specimens were identified and eight species were found: Lutzomyia longipalpis (6.3%), Lu. oswaldoi (62.7%), Lu. trinidadensis (9.2%), Lu. Goiana (7%), Lu. migonei (6.3%), Lu. intermediate (3.5%), Lu. whitmani (2.1%) and Lu. evandroi (2.8%). Regarding the collecting area, all the specimens were captured in rural areas, with records in the intradomicile (except Lu. migonei and Lu. evandroi) and in the peridomicile, with predominance of males except Lu. longipalpis, Lu. trinidadensis and Lu. whitmani, which predominated females. The presence of these species in a city with dense vegetation, climatic and environmental factors favorable to the vector, together with the fact that the municipality already has a registry of cases of American Cutaneous Leishmaniasis in humans may increase the risk of Leishmania transmission, which makes this study a relevant contribution to Public Health, when it comes to the control of neglected and tropical parasitic diseases, such as leishmaniasis.
