First Record of Four Scolytid Species (Coleoptera: Curculionidae) in the Balearic Islands (Western Mediterranean; Spain)

Abstract

Bark beetles are a group of phytophagous insects which are considered important pests of conifer and broadleaf forests. In order to carry out the characterization and monitoring of bark beetles communities present in Majorca, flight interception traps (cross-vane type trap) have been placed in three plots of pine forest (Pinus halepensis) and three plots of evergreen oak forest (Quercus ilex). The content of the traps were collected monthly and were taken to the laboratory and analyzed for their entomological determination. The main objective of this study is to present four scolytid species reported in Majorca (Balearic Islands, Spain) for the first time: Chaetoptelius vestitus, Coccotrypes dactyliperda, Xylocleptes bispinus and Xyleborus eurygraphus, as well as increase the knowledge of this coleopteran group with specific importance on forestry management in Mediterranean conditions.
