The objective of this study was to collect, identify and study population fluctuation of Coleoptera species in a forest of Eucalyptus spp., on a farm in the municipality of Pinheiro Machado, Rio Grande do Sul State. Insects were collected with light traps and ethanol traps, once every fifteen days, in the period of February 2006 to October 2007. The insects, after selection procedures, were identified based on entomological collections and specialized literature. A total of 6172 individuals were collected and distributed among 40 families and 249 species, of which 130 were identified at the species level and 119 at the family level, representing 4498 and 1674 of total individuals collected, respectively. Cyclocephala sp. 1, Cyclocephala sp. 2, Dyscinetus sp. 1, Euetheola humilis (Scarabaeidae) and Neoclytus curvatus (Cerambycidae) were the most abundant species, representing 49.28% of the individuals identified in genus and/or species. Scarabaeidae presented the highest number of individuals (2588), distributed in 37 species. The families Cerambycidae (47) and Scolytidae (40) presented the largest number of species. Individuals of Coleoptera were trapped at all collections but the largest number of individuals was trapped in December 2006 and March 2007.
