Resumo: | American Tegumentary Leishmaniasis is endemic in the province of Tucumán since 1916 where the first Argentinian case of leishmaniasis was reported. An epidemic outbreak took place in the province during 1986-1988, after that the number of cases increased gradually again between 1991-1996. Since October of 1999 sand flies captures were performed at different places associated with current and past transmission or sites identified as risky ones. The collections were carried out with CDC mini light trap and modified Shannon trap. In this study 2338 Phlebotominae were captured being prevalent Lutzomyia neivai (Lu intermedia complex) (97.7%), followed by Lu. migonei. We report Lu. shannoni for the first time in the province. Phlebotominae was abundant in the warm and humid months and showed a peak before the summer rains. Lutzomyia neivai showed a pattern (peridomestic prevalence, anthropophilia, abundance in secondary forest) consistent with other outbreak studies. Thus, the results reinforce this species incrimination as vector of leishmaniasis in the area. Domestic animals close to houses increase its abundance, and so the probable associated risk of human-Phlebotominae contact. Further studies should be done to understand the role of each Phlebotominae species in the transmission of leishmaniasis in Tucumán in order to design entomological surveillance strategies. |

La Leishmaniasis Tegumentaria Americana es endémica en la provincia de Tucumán desde 1916, lugar donde se reportara el primer caso argentino de leishmaniasis. Entre 1986-88 ocurrió un brote epidémico en la provincia, después de este hecho el número de casos aumentó en forma gradual nuevamente entre los años 1991-1996. A partir de Octubre de 1999 se realizaron capturas de Phlebotominae en la provincia en diferentes sitios asociados con transmisión actual o pasada de leishmaniasis o en aquellos sitios identificados como de riesgo. Los muestreos se llevaron a cabo con mini trampa de luz tipo CDC y trampa Shannon modificada. En el presente estudio 2338 individuos fueron capturados e identificados siendo prevalente Lutzomyia neivai (Complejo Lu intermedia) (97.7%), seguida de Lu. migonei. Se reporta por primera vez la presencia de Lu. shannoni para la provincia de Tucumán. Los datos preliminares muestran que estos insectos son abundantes en los meses cálidos y húmedos y presentan un pico de actividad anterior a las lluvias de verano. Lutzomyia neivai mostró un patrón (prevalencia peridomiciliaria, antropofilia, abundancia en bosque secundario) consistente con otros estudios de brotes epidémicos. De este modo, los resultados refuerzan la incriminación de esta especie como vector de leishmaniasis en el área. Los animales domésticos cercanos a las viviendas aumentan su abundancia, y por lo tanto el probable y asociado riesgo de contacto hombre - Phlebotominae. Estudios posteriores deben realizarse para comprender el rol de cada especie de Phebotominae en la transmisión de Leishmaniasis en Tucumán y así poder diseñar estrategias de vigilancia entomológica.
