The aim of this study was perform a surveillance of the insect fauna in soil in three grassland ecosystems of experimental farm Vale do Acarau of Universidade Estadual Vale do Acarau at Sobral, state of Ceara, Brazil, by the using of traps soil, with fortnightly collections, from March 2011 to February 2012. To characterize the insect fauna established a distribution pattern, whereas the rates of occurrence and dominance of species grouped by order, as an indicator of the frequency and the occurrence of the amount of captured. At the end, we collected and identified a total of 17,008 specimens of insects belonging to 11 orders, namely: Blattariae, Coleoptera, Dermaptera, Diptera, Hemiptera, Hymenoptera, Isoptera, Lepidoptera, Odonata, Orthoptera and Mantodea. The Order Hymenoptera was the one that stood out the largest number of individuals captured, attributing the presence of large amount of ants, are still considered common to the three ecosystems studied, according to the method employed.
