Summary: The Order Coleoptera, belonging to the Insecta Class, has great prominence in the forest environment. However, there is a need for studies that report the beetles that commonly attack processed wood in different environments, as well as their preference in relation to the wood species. Therefore, the objective was to diagnose the species of beetles that attack African mahogany wood (Khaya ivorensis, K. senegalensis and K. grandifoliola), Australian cedar (Toona ciliata) eucalyptus (Eucalyptus grandis x E. urophylla) and verify the effect of thermal change in the color of African mahogany wood (Khaya ivorensis), and eucalyptus (Eucalyptus grandis x E. urophylla) exposed to bad weather in environments in the state of Espírito Santo and to indicate more efficient prophylactic and control measures. Four 50 cm long logs were sampled along the tree of all selected species, and sawn insamples according to the tests and tests to which they were submitted. For the field test, the logs were sawn on small boards, and received treatments that consisted of samples without treatment (control); chemical treatment (boric acid and borax) and
thermal modification (180 and 200 ºC). After applying the treatments, the boards were allocated in the open and in a covered place, in each chosen place. The experiment was conducted for a period of one year (2018-2019), being evaluated monthly, through the collection of insects present in the woods and colorimetry. The thermal and chemical treatments were efficient in increasing the resistance of the wood to xylophagous insects. There is great variation in the color of the wood exposed to bad weather, especially in the first months of exposure.
