Účinnost obranných opatření proti kůrovcům smrku ztepilého v porostech s diferencovaným kalamitním základem (revír Krasov, LS Město Albrechtice)
Valentová, Aneta
The effectiveness of countermeasures (pheromone traps or trap trees) and its combination in reliance with either spring or summer generation of spruce bark beetle in areas with differentiated calamitous base were surveyed in the summer of 2012--2014 in the district of Krasov, Forest Management of the town Albrechtice. During the spring swarm the combination with equal number of each countermeasure (50 TT /50 PT) seemed to be the most effective. In the summer swarm, the ratio with dominant number of trap trees (75 TT /25 PT) was more effective, closely followed by the ratio with dominant number of pheromone traps (25 TT /75 PT).
