Bottom Line: Nyssomyia whitmani was the most frequent out of a total of 6,699 specimens collected, belonging to 16 species, followed by Psathyromyia bigeniculata and Lutzomyia longipalpis, found in all the environments investigated, though in their greatest numbers in the animal shelters.Noteworthy was the finding of two species naturally infected by flagellates: Ny. whitmani and Pa. bigeniculata.The local population and visiting tourists should be warned of the threat posed by leishmaniasis and the health authorities alerted to the need for adopting environmental sanitary measures, especially regarding such animal shelters as they seem to provide favorable conditions to the proliferation, maintenance and breeding opportunities of phlebotomines.

ABSTRACT
The aim of this study was to identify behavioral aspects of the sandfly fauna of a fishing tourism area in the municipality of Bonito (MS). Monthly captures were undertaken from December 2009 to November 2010, using automatic CDC type light traps, from 18h00 to 06h00, in a forested area, a savannah area, peridomiciles and animal shelters near peridomiciliary areas. Nyssomyia whitmani was the most frequent out of a total of 6,699 specimens collected, belonging to 16 species, followed by Psathyromyia bigeniculata and Lutzomyia longipalpis, found in all the environments investigated, though in their greatest numbers in the animal shelters. Ny. whitmani exhibited its highest frequencies during the dry months, coincident with the fishing season, when the risk of transmission of cutaneous leishmaniasis for tourists and inhabitants increases. Noteworthy was the finding of two species naturally infected by flagellates: Ny. whitmani and Pa. bigeniculata. The local population and visiting tourists should be warned of the threat posed by leishmaniasis and the health authorities alerted to the need for adopting environmental sanitary measures, especially regarding such animal shelters as they seem to provide favorable conditions to the proliferation, maintenance and breeding opportunities of phlebotomines.

Mentions: Capture sites: A total of nine sites were sampled in different environments (Fig. 1): peridomiciliary areas near fruit trees,native grass and tuberous vegetables (A1), native species of trees, fruit trees andbamboos (A2) and bordered by a stream, within a bamboo grove, near fruit and ornamentaltrees (A3); area of savannah with selective extraction of timber and native species oftrees (A4); gallery forests with some secondary vegetation which grew after theselective extraction of timber (A5, A6) and animal shelters such as a pigsty (A7), ahenhouse (A8) and a perch (A9), near peridomiciliary areas.
