Abstract:
To study the sand fly fauna, surveys were performed atfour different leishmaniasis-endemic areas of Ecuador, during February 2013 andApril 2014. The conventional Shannon trap was modified and simplified to anewly named mini-Shannon trap for its multiple uses at different study sites,such as limited, forested and narrow spaces. The mini-Shannon, CDC light trapsand the protected human landing method were employed for sand fly collection.The species identification of sand flies was performed mainly based on themorphology of spermathecae and cibarium, after dissection of freshsamples. In this study, therefore, onlyfemale samples were used for analysis. A total of1,480 female sand flies belonging to 25 Lutzomyia species were collected. Numbers of the female sand fliescollected by each trap were 417 (28.2%) by the mini-Shannon trap, 259 (17.5%)by CDC light trap and 804 (54.3%) by human landing. The total number of sand flies per trap collected bydifferent methods was markedly affected by study sites, probably because ofdifferent species compositions at each locality. Further, as an additionalstudy, the attractiveness of sand flies against the mini-Shannon traps poweredwith LED White-light and LED Black-light, waspreliminary tested, together with CDC light trap and human landing. In the test,a total of 426 sand flies of nine Lutzomyia species, seven man-biting and two non-man-biting species, were collected by threecapture trials during May and June 2014 in an area endemic for leishmaniasis(La Ventura). The Black-light equipped trap was relatively superior in capturenumbers to the White-light equipped one, but no significant difference wasobserved statistically between the two traps.
