Efficacy of chipping logs to eliminate Anoplophora glabripennis
In USA, the eradication programme against Anoplophora glabripennis (EPPO A1 quarantine pest) includes the destruction of infested wood by chipping and incineration. The efficacy of chipping logs to destroy wood-boring insects was studied. Surrogate worms (plastic worms) of different sizes, as well as live larvae and pupae of several insect species (Lymantria dispar, Phyllophaga annina) were placed in logs. Results showed that although chipping did not cause damage to all plastic worms, all insects (larvae and pupae) were killed by the treatment. The authors felt that to eliminate A. glabripennis from infested wood, chipping without incineration is sufficient.
