Abstract. Cedrela odorata and Jacaranda copaia are important species in the neotropics for protection and production. Xylophagous insects that attack the mentioned woods, have been little studied. Scolytinae that bore the mentioned woods diversity's was characterized and compared among species, season and ecosystem; similarity between forest species was studied; its association and woods was tested; and the damage produced by this and other insects was measured. Wood logs were exposed in a forest, grassland and its ecotono, for a month, in a rainy and dry season, then the insects from its interior were extracted. The captured species were Xyleborus ferrugineus, X. affinis and Platypodini. Scolytinae that attack the studied woods' diversity was low, lowest in J. copaia, the dry season and in the grassland. The fauna was similar between the two woods. Association between scolitins and wood species was not proved. The attacks were low and do not damage the logs seriously, been scolitins the most damaging insects. Differences found are due because captured scolitins are generalist and the environmental differences, mainly. It is recommended to harvest the wood in dry season and take it to grasslands to avoid xylophagous insects attack.
