Flebótomos (Diptera: Psychodidae) del departamento de Guaviare, Colombia, con nuevos registros para el país

Abstract

Introduction: Although cases of leishmaniasis have been reported in the province of Guaviare, Colombia, no entomological studies were included to identify the Lutzomyia sand fly vector species in that area. Objective: Lutzomyia species were identified from four townships of Guaviare. Probable vectors were named based on those species involved in transmission in other areas. Materials and methods: Sampling was undertaken with CDC light traps suspended at heights between 1.5 m and 9 m. Additional sand flies were collected with Shannon traps and by aspiration of adult flies from daytime resting sites. Results: Sand flies belonging to 37 different species were collected. 35 of them were recorded for the first time in Guaviare Province. Four species were new records for Colombia: Lutzomyia begonae, L. campbelli, L. sericea and L. nematoducta. The most abundant species were L. hirsuta 24.3% (148/610), L. yuilli 15.2% (93/610), L. davisi 10.3% (63/610), followed by L. fartigi, L. carrerai, L. antunesi, L. flaviscutellata and L. olmeca bicolor. Conclusion: Seven of these species of have been associated previously with endemic or epidemic transmission of leishmaniasis.
