Abstract
Over 30% of the sand flies collected in emergence traps from a "terra firme" forest in the Amazon Basin of Brazil were known vectors of cutaneous leishmaniasis. Fifteen species of sand flies were collected from a region where at least 50 species are known to occur. The majority of specimens were taken from traps set during the month of November. It was estimated that 100 m2 of terra firme forest will only produce an average of. 4.1 sand flies per day; however, this productivity may reach as hign as 14 sand flies per 100 m2 per day.
