We analyzed the fluctuation of the families of Coleoptera: Cerambycidae, Lyctidae, Anobiidae, Bostrichidae and Curculionidae. Six sampling points were arranged along the river, five points being inferred in reforestation carried out in the basin and a point in the control area of natural regeneration the amount of Guapiaçu river. The collection period started in January 2013, and ended in December 2015. Through quali-quantitative data, there is a greater population density of sub-family Scolytinae in periods of high temperature and humidity and areas more populated by pioneer species used in forest restoration. After the end of the monitoring period, we proposed a model of environmental assessment through the frequency of occurrence of families of coleobrocas collected in forest fragments. Keywords: forest entomology, conservation of natural areas, ecology of forest ecosystems.
