Forecasting infestation by Coraebus undatus (Coleoptera, Buprestidae) in cork oak forests
International Journal of Pest Management 58 (3), 275-280
Abstract: Larvae of the buprestid beetle Coraebus undatus feed on the cork-generating layer of cork oaks, seriously affecting cork quality and reducing the monetary value of cork plank which is used by the wine industry. The galleries of C. undatus are only observable after cork bark has been removed; therefore if, prior to harvesting, trees that have a high likelihood of having been infested can be identified, control measures can be applied to good effect, thus reducing the cost of insecticide applications. Here, we identify the variables that can provide reliable information on infestations. Prominent among these is the presence of chlorotic spots, as it provides direct information on presence of C. undatus galleries. Other useful variables are the degree of defoliation and, as regards ants, the absence of Crematogaster scutellaris and the presence of Camponotus cruentatus.
