    Description

    Numbers of pine shoot beetles Blastophagus piniperda and B. minor trapped in pheromone traps within a pine beauty moth (Panolis flammea) outbreak area were significantly greater in zones with total 100% defoliation (26.8±10.4 and 5.8±2.0 beetle/trap, both species respectively) as compared to undefoliated stands (1.8±1.3 and 1.4±1.0) and zones with moderate 50% (3.7±1.5 and 3.3±1.2) and heavy 75% defoliation (6.1±2.4 and 1.8±0.9, respectively). Peak flight of Blastophagus piniperda was observed in the last part of April, whereas Blastophagus minor was trapped at constant but small numbers for approximately a month up until the middle of May.
