    Avaliar os Laboratórios Municipais de Entomologia dos municípios do Mato Grosso do Sul na identificação de mosquitos para medidas de prevenção de arbovírus. Os laboratórios foram analisados de acordo com os parâmetros de qualidade e na identificação de larvas e pupas de Aedes aegypti e Aedes albopictus do técnico de laboratório, entre outubro de 2015 e outubro de 2016. Todos os laboratórios possuíam materiais consumíveis; apenas 26,67% possuíam estrutura física adequada e 29,33% dos microscópios eram bons; a média de respostas corretas do técnico na identificação de larvas e pupas foi de 77% ± 7,88. A baixa qualidade da estrutura física do laboratório e dos equipamentos de microscopia tem um impacto direto na identificação de mosquitos. Apesar do treinamento oferecido à equipe técnica, há uma baixa qualidade na identificação de mosquitos, comprometendo os Laboratórios Municipais de Entomologia

    Fauna of phlebotomine sand flies (Diptera, Psychodidae) in areas with endemic American cutaneous leishmaniasis in the State of Mato Grosso do Sul, Brazil. The aim of this study was to investigate the ecological aspects of the main vectors of American cutaneous leishmaniasis (ACL) in four monitoring stations situated in the municipalities of Naviraí, Nova Andradina, Novo Horizonte do Sul and Rio Verde de Mato Grosso. For each monitoring station, the captures of sand flies were undertaken each month from July 2008 to June 2010 using CDC and Shannon traps. The CDC traps were installed simultaneously for three consecutive nights in three collection sites: intradomicile, peridomicile and edge of the forest. A Shannon trap was installed from dusk to 10 pm, inside the forest, one night per month. A total of 7,651 sand flies belonging to nine genera and twenty-nine species were captured. Nyssomyia neivai (52.95%), Psathyromyia hermanlenti (10.91%), Psathyromyia runoides (9.16%), Nyssomyia whitmani (7.95%), Psathyromyia aragaoi (4. 89%), Nyssomyia antunesi (3.14%) and Evandromyia bourrouli (2.20%) were the most frequent species. Approximately 65% of the sand flies were collected in the forest environment. The municipalities presented significantly different indexes of species diversity. Naviraí presented the lowest species diversity index, however, it showed the highest abundance. Novo Horizonte do Sul had the highest species diversity index, but the lowest abundance (< 5%). It is noteworthy the occurrence of vector species of Leishmania in the areas studied, especially in Naviraí, where Ny. neivai presented high frequencies which may explain the increased number of ACL cases in this municipality
