ABSTRACT
By employing protected human bait landing and modified Shannon light trap, a total of 1924 phlebotomine sand fly Lutzomyia spp. were captured in an area from which L. (V.) guyanensis was reported as the causative parasite of cutaneous leishmaniasis (CL). The sand flies captured alive were dissected and identified at species level, based mainly on their spermathecae. At the same time, the sand flies dissected were searched for the Leishmania parasites by microscopic-test, and later on by PCR-test. No positive sand flies were detected by both tests, while considerable numbers of anthropophilic sand fly species of the genus Lutzomyia were observed as probable vectors of the Leishmania parasite in the areas. Those were eight species, Lu. robusta, Lu. trapidoi, Lu. maranonensis, Lu. gomezi, Lu. shannoni, Lu. migonei, Lu. punctigeniculata and Lu. spathotrichia. Among them, the first two species Lu. robusta and Lu. trapidoi were most dominant, suggesting probable vectors of the Leishmania parasite prevailing in the area. Lu. punctigeniculata and Lu. spathotrichia were for the first time recorded for the Manabí province, Ecuador. These findings provide basic information useful for future planning of the control and management of the disease in the areas, though further study to incriminate the vector sand fly remains.
