“…hirsuta were the commonest species collected in forested areas of Rio de Janeiro, on human bait 6 5 , it was collected at Parati (ca. 5 m a. s. l.), in an area similar to Itaguaí, although closer to the sea 1 . These Psychodopygus species therefore seem to have a patchy distribution in SE Brazil, including the possible replacement of Lu.…”

Abstract Abstract Abstract The phlebotomine sandfly fauna of a primary forest reserve at Morretes (eastern Paraná State) was studied, using CDC-like light traps, one night per month, at canopy and ground level, between April 1995 and March 1996. A total of 3,106 insects were collected, identified as belonging to nine species. Lutzomyia ayrozai and Lu. geniculata were predominant, seven other species also being present. Monthly mean temperature, rainfall and the temperature of the collection night significantly influenced the numbers of Lu. ayrozai while the two first factors influenced the numbers of Lu. geniculata, besides the collected quantities of females of the two species. The influence of the factors on Lu. ayrozai numbers was more immediate than in those of Lu. geniculata. Numbers of both species and of the females of Lu. geniculata collected in different seasons, but not at the different heights, varied significantly. Differences between the behaviour of Lu. ayrozai in Morretes and in other regions could be attributed to environmental differences and/or to regional variations in the species, which could constitute species complexes. Hourly variations of collections were different in the species and seasons. Key-words: Key-words: Key-words: Key-words: Key-words: Phlebotominae. Fauna. Seasonal variation. Psychodidae.

Resumo Resumo ResumoResumo Resumo A fauna de flebotomíneos de uma reserva de floresta primária em Morretes (leste do Estado do Paraná) foi estudada, utilizando armadilhas luminosas tipo CDC, uma noite por mês, no nível do solo e da copa, entre abril de 1995 e março de 1996. Um total de 3.106 insetos foi coletado. Lu. ayrozai e Lu. geniculata foram predominantes, além de outras sete espécies. A temperatura média mensal, a pluviosidade e a temperatura na noite de coleta influenciaram significativamente as quantidades de Lu. ayrozai e os dois primeiros fatores influenciaram Lu. geniculata, além das quantidades de fêmeas coletadas de ambas as espécies. A influência do aumento dos fatores nas quantidades de Lu. ayrozai foi mais imediata que nas de Lu. geniculata. As quantidades coletadas de ambas as espécies e das fêmeas de Lu. geniculata nas estações, mas não nas alturas, foram significativamente diferentes. As diferenças entre os comportamentos de Lu. ayrozai em Morretes e em outras regiões poderiam ser atribuídas a diferenças ambientais e/ou a variações regionais na espécie, que poderia constituir um complexo de espécies. As variações horárias nas coletas foram diferentes nas espécies e estações.

“…intermedia, preferring to feed on donkeys, chicken and dogs. [22][23][24][25][26] The most direct evidence for peridomestic transmission comes from the finding that ACL risk was greatest for those who most frequently slept outdoors in the backyard. A marked dose-response effect was observed with the number of months per year spent sleeping outdoors.…”

Abstract. A case-control study was carried out during 1990−1994 to identify risk factors associated with American cutaneous leishmaniasis (ACL) in Santiago del Estero, Argentina. The study subjects consisted of 171 cases and 308 controls matched by age, sex, and place of residence. The analysis was performed by conditional logistic regression. Risk factors found to be significantly associated with ACL were related to indoor transmission (few rooms in the house, dirt floor, and a permanent opening in lieu of a window); peridomestic transmission (presence of a pond or woodland within 150 m of the house and an agricultural area within 200 m of the house); and human behavior (sleeping in the backyard, collecting water, bathing, and performing agricultural activities). Most transmission appears to have occurred indoors and in the peridomicile. These environments should be included in further research and control policies.

“…In Rio de Janeiro, to date, the frequency of L. whitmani has always been recorded with low indices (Rangel et al 1986, 1990, Carvalho 1993, Aguiar et al 1993). More recent studies have identified L. whitmani in preserved areas, as well as in shelters for domestic animals, and it is also the second most frequent species to bite humans in the peridomicile (Souza et al 2001).…”

Lutzomyia intermedia and Lutzomyia whitmani occur sympatrically in the district of Posse, municipality of Petrópolis, in the State of Rio de Janeiro (114 km from the city of Rio de Janeiro), where sand flies were captured weekly for three consecutive years in both the peridomicile and forest, in two first years from 18:00 to 22:00 h, using a Shannon trap and CDC light traps. The anthropophilic habit was assessed by recording the specimens that bit the human captors. Considering the different capture types and sites, the following species were identified: Brumptomyia brumpti, B. cardosoi, B. guimaraesi, Lutzomyia amarali, L. longipalpis, L. microps, L. costalimai, L. edwardsi, L. firmatoi, L. migonei, L. termitophila, L. tupynambai, L. fischeri, L. pessoai, L. lutziana, L. shannoni, L. barrettoi, L. intermedia, L. whitmani, L. lloydi, and L. minasensis. L. intermedia (38.3%) and L. whitmani (38.6%) predominated. L. intermedia predominated in the peridomicile, where it displayed more intense anthropophily, while L. whitmani displayed greater density in the banana plantations and forest, preferential sites for biting humans. Studies on seasonality showed that while L. intermedia displayed greater density in the hottest months of the year (December, January, and February), L. whitmani was abundant in the coolest months (June, July, and August), although both occurred throughout the year
