Resumo: Esse estudo avaliou a fauna acarina presente em amostras de poeira de diferentes substratos em 58 residências da cidade de Campinas/SP. As amostras foram coletadas de despensas, tapetes (sala e quarto), sofás, cortinas (sala e quarto) e colchões (faces superior e inferior, incluindo o estrado). Foi avaliado um total de 368 amostras de poeira, sendo observados 3.447 ácaros. A principal subordem observada foi a Acaridida (n=2.605 ácaros; 75,6% do total). Nessa subordem, a principal família observada foi a Pyroglyphidae (n=1.833; 53,2%), sendo o ácaro Dermatophagoides pteronyssinus a espécie mais prevalente. A segunda família mais importante foi Glycyphagidae (n=496; 14,4%). O principal local de infestação acarina foi a face inferior dos colchões, onde se observaram 1.808 ácaros (52,4% do total de ácaros). Outros locais de importante ocorrência acarina foram a face superior dos colchões (12,7%) e os sofás (11,0%) Ver menos

Abstract: The aim of this study was to evaluate mite numbers and species in house dust samples from different dwellings sites. A total of 58 homes in Campinas/SP was chosen. Samples were collected once from pantries, rugs (Iiving rooms and bedrooms), sofas, curtains (Iiving rooms and bedrooms) and upper and lower surfaces of mattresses, in the last also included the bed frames. A total of 368 dust samples was analyzed under optic microscope, in which 3,447 mites were counted. The main acarine suborder was Acaridide (n=2,605 mites; 75.6% of total mite number). In this suborder, the mainly acarine family was Pyroglyphidae (n=1,833; 53.2%), Dermatophagoides pteronyssinus as the principal specie. Glycyphagidae was the second most prevalent acarine family observed (n=496; 14,4%). lower mattress surface and bed frame were the most important in-house site of mite infestation (n=1,808 mites; 52.4% of total mite number). Other important sites of mite infestation were upper mattress surface (12.7%) and sofas (11.0%) Ver menos
