Contribution to the study of xylophagus insects and their role in the decline of Alep pine (Pinus halepensis mill.) in El Ouldja’s Megsem forest (Setif - Algeria)
Pinus halepensis Mill., is an essence from the Pinaceae family. This importance is attributed to its economic and aesthetic values. Despite its robustness, this tree is subject to many degradation factors including, for some time, that of wood-boring insects which for the most part are fatal. The purpose of this investigation is to classify these insects, define their role in pine decline and evaluate the damage caused by them in the Megsem forest. The result of the study shows that members of the Curculionidae, Cerambycidae and Buprestidae families could be held responsible for the majority of the damage observed on the pine
