The objective of the research was to determine the natural durability in ten timber species from secondary and primary residual forests in the Ucayali region, Perú, from infection with two xylophagous fungi Pycnoporus sanguineus (which causes white-rot) and Lenzytes erubencens (causal agent of brown rot). The wood samples analyzed were: Apeiba membranacea, Apuleia molaris, Brosimun utile, Croton matourensis, Jacaranda copaia, Matisia cordata, Septotheca tessmannii, Schizolobium amazonicum, Simauroma amara, Terminalia oblonga; powered by two xylophagous fungi, which were treated at the carpentry of the National University of Ucayali. The analysis of the study was experimental, according to the guidelines of the ASTM D 2017-81 Standard, under in vitro conditions of the treated material. Once the range of the species rot index was achieved, the average per species of xylophagous fungus, the standard deviation, the coefficient of variation and the confidence parameters were calculated in accordance with COPANT in 1974. The results established the relation among xylophagous fungi species and the height of the trunk, both as a function of natural durability. It was concluded, according to the type of risk, the management that could be given to the studied woods and the recommendations for the correct use of vulnerable woods.
