Resumo
Este trabalho teve como objetivo identificar os ácaros edáficos das subordens Actinedida e Acaridida coletados no campus Luiz de Queiroz da Universidade de São Paulo (ESALQ/USP). Coletas de solo foram feitas em três ambientes diferentes, uma área de mata residual secundária, outra de cultura perene, representada pelo plantio de seringueira (Hevea brasiliensis Müll. Arg.), clone RRIM 600, e outra de culturas anuais (milho seguido de feijão). Coletas de folhedo foram realizadas apenas na mata secundária e no plantio de seringueira. A extração da acarofauna edáfica foi feita por meio do método de Berlese-Tullgren modificado. Foi constatado um total de 32 espécies pertencentes a 22 gêneros de 14 famílias da subordem Actinedida em solo e folhedo. Os ácaros da família Eupodidae foram os mais numerosos nos dois substratos e nos três ambientes estudados. Eupodes sp. 2 (Eupodidae) foi a espécie mais numerosa. Foi constatado um total de sete espécies pertencentes a seis gêneros de quatro famílias da subordem Acaridida. Tanto no solo quanto no folhedo dos ambientes estudados, Acaridae foi a família mais abundante, destacando-se uma espécie do gênero Tyrophagus.
The objective of this work was to identify the edaphic mites of the suborders Actinedida and Acaridida collected on the campus Luiz de Queiroz, University of São Paulo. Soil samples were taken from three different environments, i.e., a residual secondary forest, a perennial crop represented by a rubber tree plantation (Hevea brasiliensis Müll. Arg.), clone RRIM 600, and an area of annual crops (corn followed by beans). Litter samples were taken only from the secondary forest and the rubber tree plantation. Mites were extracted using a modified Berlese-Tullgren apparatus. A total of 32 species belonging to 22 genera of 14 families of the suborder Actinedida was found in soil and litter. Eupodidae mites were the most numerous in both substrates in the three environments. Eupodes sp.2 (Eupodidae) was the most numerous species. A total of seven species belonging to six genera of four families of the suborder Acaridida was found. Acaridae was the most numerous family in this suborder in both soil and litter of all three environments, with a predominance of a species of Tyrophagus.
