  This study assessed infestation of Proholopterus chilensis in Nothofagus obliqua trees in the Valdivia Province, Chile. P. chilensis is a native xylophagous insect that produces internal galleries in the stem during larval stage, decreasing value recovery in the most profitable log of the tree. The objectives of the study were to evaluate the current infestation of P. chilensis in Valdivia Province, to investigate the relationships among infestation, trees, site and flora attributes, to increase information about P. chilensis infestation patterns, and to make suggestions about silvicultural practices that could reduce damage. Results indicated that the level of infestation was low, compared with previous data. Hierarchical logistic regression models showed that estimated tree height and stand density were significant to explain probability .. View More»
