Estrada, Luis Gregorio | 2019-10-02
Studies of the insects associated with the epidemiological cycle of leishmaniasis on the Caribbean coast of Colombia have been focused on the departments of Sucre and Córdoba. The phlebotomine sand fly fauna of the rest of the Caribbean region remains little known. In the present study four species of the genus Lutzomyia are reported from the department of Cesar for the first time. Sand flies were sampled using two CDC light traps with blue color LEDs at Balneario Hurtado, a tourist area in the city of Valledupar. A total of 50 phlebotomine sand flies were collected, of which the species Lutzomyia cayennensis cayennensis (38 % of the sample) and L. trinidadensis (14 %) were already known from the departament. Specimens of L. evansi (28 %), L. venezuelensis (10 %), L. micropyga (6 %) and L. rangeliana (2 %) represent the first records of these species for Cesar, raising the number of known occurrences from the department to eight species. Noteworthy among the new records is the sandfly L. evansi, recognized vector de Leishmania spp. in the Colombian Caribbean coast.
