Phlebotomine Fauna (Diptera: Psychodidae) and Infection by Leishmania spp. in Forest Fragments of a University Campus, Western Amazon.

Forest fragments consist of important ecosystems for the maintenance of sand fly populations and Leishmania hosts. This study sought to identify the phlebotomine fauna and its infection by Leishmania spp. in forest fragments on the campus of the Federal University of Acre (UFAC), Western Amazon. Monthly collections with CDC traps were carried out from March 2020 to June 2021, in four forest fragments of UFAC. Male and female insects were processed and identified at species level. A sample of females was subjected to polymerase chain reaction (PCR) analysis to verify the presence Leishmania DNA. In total, 465 specimens were collected, of which 238 were males and 227 were females. The most frequent species were Nyssomyia antunesi (Coutinho, 1939) (47.3%), Trichophoromyia sp. (Mangabeira, 1942) (18.70%), and Ny. whitmani (Antunes & Coutinho, 1939) (8.81%). Molecular analysis detected the presence of Leishmania (Ross, 1903) DNA in a specimen of Ny. antunesi, and another one of Evandromyia walker (Newstead, 1914). The forest fragments of the university campus harbor a diverse sand fly fauna with the presence of Leishmania DNA in these insects, in addition to the presence of other species considered incriminated vectors of Leishmania parasites.

First official record of Aedes (Stegomyia) albopictus (Diptera: Culicidae) in the Acre State, Northern Brazil.

Aedes (Stegomyia) albopictus (Skuse, 1854) was reported in Brazil for the first time in 1986 and has shown marked expansion throughout the Brazilian territory. During a routine activity to control dengue fever conducted by the Division of Entomology of the Municipal Health Department in Rio Branco city, adults and immatures of Culicidae were collected in a peri-urban area. The identified Culicidae forms indicated that they belonged to the species Ae. albopictus. This is the first official record of the presence of Ae. albopictus in the Acre State, confirming its current presence in all Brazilian states.

Epidemiologia da dengue na cidade de Rio Branco - Acre, Brasil, no período de 2000 a 2007 / Epidemiology of dengue in the city of Rio Branco- Acre, Brazil, from 2000 to 2007

Objetivo Caracterizar a ocorrência de dengue na cidade de Rio Brando, estado do Acre, no período de 2000 a 2007, no tempo, no espaço e segundo infestação pelo Aedes aegypti e vari- áveis demográficas, socioeconômicas, ambientais e climáticas. Métodos Foi realizada uma descrição da incidência de dengue (CI) e da infestação predial pelo Aedes aegypti (IIP) no período de 2000 a 2007 a partir de dados secundários. Descreveu-se a incidência da dengue em relação ao sexo, faixa etária e escolaridade. O Coeficiente de Incidência e o Índice de In- festação Predial foram testados para aferição de correlações com variáveis climáticas, demo- gráficas, ambientais e socioeconômicas. Foi aplicada a técnica de geoprocessamento com o uso da estatística espacial de Moran Global e Local (LISA) para avaliar a autocorrelação es- pacial dos coeficientes de incidência de dengue entre as localidades urbanas da cidade. Resul- tados - A epidemiologia da dengue na cidade é caracterizada por elevada incidência e intensa infestação predial pelo Aedes aegypti. Não existe diferença na incidência de dengue entre ho- mens e mulheres e a faixa etária mais acometida compreende jovens e adultos de 15 a 49 anos e escolares que não concluíram o ensino médio. A distribuição da doença mostra um padrão sazonal com elevação da incidência nos períodos chuvosos e regressão nos períodos secos.
