Colonization of oak stumps by the oak pinhole borer in temperate forests and the efficacy of pheromone traps: Implications for pest management

Introduction The present changes in climate and land use have led to an increase pest population densities. oak pinhole borer, Platypus cylindrus , is one of the ambrosia beetles, which are known infect wood tissue with fungi from their mycangia. These responsible for cellulose degradation. This species now more frequent timber damage throughout Europe. Therefore, it assumed that there a high risk P. outbreaks future possible subsequent diebacks. We focused on (1) influence stump diameter attraction abundance; (2) trapping efficacy by specific pheromone impact nontarget arthropods; (3) interannual trap catches. Methods research was performed 2015–2017 postharvest survey stumps. further analyzed catches arthropods traps compared ethanol-baited traps. Results discussion In total, 12,504 adults were trapped during 3 years study. abundance positively correlated changes. type compound used affected efficacy. However, did not beetles. consider stumps be reservoir borer. we recommend debarking or removal, especially case larger (over 61 cm).
