We analyzed the population fluctuation and feeding guilds of the families of Termites: Kalotermitidae, Rhinotermitidae and Termitidae. Six sampling points were arranged along Guapiaçu river, five points being inferred in reforestation carried out in the basin and a point in a regeneration control area. Quantitative and qualitative surveys followed standard protocols and the samples were obtained directly, without baits. Thirty species within 25 genera were identified and the family Termitidae was the most frequent. The termite fauna of the control point P06 was the richest. From the frequencies of occurrence of the species related to their trophic guild, an ecological evaluation table of the environments was proposed. The P05 area, rich in plant species, presented the greatest similarity to the natural regeneration area P06. The majority of the species was classified as xilophagous. Keywords: forest entomology, conservation of natural areas, ecology of forest ecosystems.
