“…intermedia is abundant in many endemic areas of ACL, where it has adapted to habitats modified by human activity, showing an increased predisposition to enter houses and bite both man and dogs (Falqueto 1995, Marzochi & Marzochi 1997, Domingos et al 1998).

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.

“…Both species are suspected of transmitting cutaneous leishmaniasis due to their very high frequencies at foci of the diseases in southern and southeastern regions of Brazil (Andrade Filho 2003) and to the fact that they have been found naturally infected by flagellates by Rangel et al (1984) (N. intermedia), Forattini et al (1972) and Casanova et al (1995) (N. neivai, presumably).…”

ABSTRACT. Polymorphism, inter-population and inter-specific variation in Nyssomyia intermedia (Lutz & Neiva) and Nyssomyia neivai (Pinto) (Diptera, Psychodidae, Phlebotominae). Nyssomyia intermedia (Lutz & Neiva) and Nyssomyia neivai (Pinto) are morphologically very close and both present great variation in some structures. The objective of this study is a description of the variation among the females of these species in populations from the States of Minas Gerais and São Paulo. The morphological structures studied were the number of horizontal teeth in the cibarium and the number of rings and the shape of the terminal knob of the spermathecae. The spermatheca rings are significantly more numerous in N. intermedia than in N. neivai and the simple shape of the terminal knob predominated in both species. Regarding the cibarium, eight to eleven teeth have been found in both species, with up to twelve teeth in the latter. The number of horizontal teeth and the shape of the terminal knob of the spermathecae were variable throughout the populations of both species and all structures were polymorphic in the populations studied.
