The objective of this research was to study population fluctuation of Coleoptera species in thecounty of Santa Bárbara, Minas Gerais, Brazil in a Eucalyptus grandis plantation. Coleoptera individuals were collected with five light traps during one night every fifteen days from July 1993 to June 1994. A total of 5,641individuals of this order was collected, being 866 and 4,775 identified at genus and/or species and family levels, respectively. The family with the highest number of individuals was Carabidae with 74.55%, followed by Scarabaeidae and Elateridae with 10.12% and 3.98% of individuals of this group, respectively. Most species collected were Isonychus albicinctus (Scarabaeidae), followed by Colaspis jolivetti (Chrysomelidae) and Cyclocephala laminata (Scarabaeidae) with 412, 317 and 16 individuals which represented 54.50, 36.61 and 1.85% of individuals identified per species, respectively. The region of Santa Bárbara presents a diversified fauna of Coleoptera, but with low outbreak possibilities. Population peaks of Coleoptera species ocurred in Novemberand December, when monitoring of these insects is recommended.
