Further evidences of Leptoglossus as causal agent of cone yield loss in Mediterranean stone pine
Since its first detection in Europe in 1999, the invasive Western Conifer Seed Bug, Leptoglossus occidentalis, has been gaining increasing attention in the Mediterranean countries. This interest is mainly due to the putative impact of L. occidentalis on the edible seed of the Mediterranean stone pine, Pinus pinea L., a gourmet nut whose current retail price can exceed 70-100 €/kg.
