Abstract. The present study had the objective of estimating the abundance and monthly frequency of vector phlebotomines for American cutaneous leishmaniasis (ACL) in the municipalities of Saquarema, Rio Bonito, Piraí and Rio Janeiro, in the state of Rio de Janeiro. Seven sites located in these municipalities were monitored over a 10 to 12-month period. Lutzomyia migonei (França) Lutzomyia (Pintomyia) fischeri (Pinto) and Lutzomyia (Nyssomyia) intermedia (Lutz & Neiva) the vectors for ACL, were recorded in all four of these municipalities. In this study, it was noteworthy that Lutzomyia (Lutzomyia) longipalpis (Lutz & Neiva) the vector of visceral leishmaniasis (VL) was registered. In addition to these vectors, three other phlebotomine species, including Lutzomyia edwardsi (Mangabeira), Lutzomyia sallesi (Galvão & Coutinho) and Lutzomyia firmatoi (Barreto, Martins & Pellegrino) were captured in peridomestic environments at the seven monitoring sites (MS) over a 1476-hour period. A total of 23,187 specimens were captured leishmaniasis vector species accounted for 99.6% of the specimens captured. Lutzomyia (N.) intermedia presented the highest abundance (SISA = 1.0) and was recorded at all monitoring sites, with the highest mean Williams values. Lutzomyia migonei was the second most abundant and was found at all sites except MS 6 (SISA = 0.66). Lutzomyia (L.) longipalpis, Lutzomyia sallesi, Lutzomyia firmatoi and Lutzomyia (P.) fischeri were occasionally observed at the MS . These studies point to the need for adoption of policies involving actions of health education, associated with the notion of environmental management and the basics concepts of the disease, as element of success of an integrated program of entomological surveillance and control of American cutaneous leishmaniasis.
Introduction: Nyssomyia intermedia is an important vector of American cutaneous leishmaniasis. Methods: Sand flies were captured in a Shannon trap and after landing on human collectors and retrieved monthly. Nocturnal activity was estimated using a log-linear model. Results: Peak sand fly collection in the Shannon trap occurred in summer and winter, and peak fly collection on humans occurred in spring and summer. Conclusions: Ny. intermedia was captured in both the hottest and coldest months, indicating its adaptability to different seasons and the possibility of disease transmission at any time of the year in Campus
