ABSTRACT Mangabeira is a native fruit tree from Brazil, which provides a delicious fruit to taste and beneficial to health, whose information about the seedlings production will assist the entire productive chain of this important species. The aim of this research was to evaluate protected environments and substrates compositions in the formation of mangabeira seedlings. For this, two greenhouses with different screens were used, the first covered with aluminized thermo-reflective screen of 50% shading and the second with black screen of 50% shading. Inside the environments, were tested substrates derived from combinations of various proportions of bovine manure (M), soil (S), medium vermiculite (MV), super fine vermiculite (FV) and fine sand (FS). For each environment of cultivation was adopted a completely randomized design to evaluate the substrates, with five replicates of eight plants. The environments were compared by analysis of experiments groups. The results showed that both protected environments are suitable for mangabeira seedlings. In the aluminized screen is indicated for the formation of seedling in the substrate with 20% M + 30% S + 10% MV + 30% FV + 10% FS while in the black screen is indicated for seedlings in the substrate with 10% M + 30% S + 10% MV + 10% FV + 40% FS and with 10% M + 30% S + 40% MV + 10% FV + 10% FS.

O intuito deste estudo foi avaliar as espécies acarinas encontradas em amostras de poeira de cortinas presentes em 33 salas e 22 quartos de um total de 41 domicílios na cidade de Campinas, SP. Foram encontrados 148 ácaros. Desse total, 83 foram encontrados na sala de TV (56,1% do total) e 65 nos quartos (43,9%). As principais subordens encontradas foram: Acaridida (n = 79; 53.4%), Actinedida (n = 53; 35.8%), Oribatida (n = 14; 9.5%) e Gamasida (n = 2; 1.3%). As principais famílias observadas foram: Pyroglyphidae (n = 61; 41,2% do total), Eriophyidae (n = 25; 16,9%), Tarsonemidae (n = 15; 10,1%) e Glycyphagidae (n = 13; 8,8%). Não houve diferença significativa no número de ácaros observados nas amostras da sala e do quarto.

The aim of this study was to investigate the mite fauna present in 33 living room and 22 bedroom curtain dust samples from 41 different homes in the southern Brazilian city of Campinas, SP. A total of 148 mite bodies were found. Of these, 83 were found in living-room curtain samples (56.1% of total) and 65 were in bedroom curtain dust samples (43.9%). The most frequently observed mite suborders were: Acaridida (n = 79; 53.4%), Actinedida (n = 53; 35.8%), Oribatida (n = 14; 9.5%), and Gamasida (n = 2; 1.3%). The most frequent families were Pyroglyphidae (n = 61; 41.2%), Eriophyidae (n = 25; 16.9%), Tarsonemidae (n = 15; 10.1%), and Glycyphagidae (n = 13; 8.8%). No statistical difference was observed between the number of mites found in the samples from living room and bedroom curtains.
