The lack of effective methods of forest protection against bark beetles in Norway spruce stands was the reason for undertaking the studies aimed at the assessment of efficacy of pheromone traps Trinet P that act as an ‘attract and kill' system to reduce the population of spruce bark beetle Ips typographus (Col.: Curculionidae: Scolytinae). The Trinet P trap consists of a triangular stand, on which...
Od 1983 roku na obszarze Bawarskiego Lasu i Szumawy obserwuje się zjawiska niesprzyjające świerkowi pospolitemu (huragany, okiść, wyższe temperatury latem). Czynniki te spowodowały masowy pojaw kornika drukarza w górnoreglowych świerczynach. Obydwa parki narodowe przyjęły odmienny sposób postępowania z gradacją tego chrząszcza. Na Szumawie zastosowano czynne metody ochrony drzewostanów m.in. korowanie...
This study dealt with the species distribution and frequency of ophiostomatoid fungi associated with the bark beetle Ips typographus on Norway spruce and Scots pine in north-eastern Poland. At all locations high spruce bark beetle damage has occurred in 2002-2003. Fungi were isolated from beetles and from brood systems of trees infested by the spruce bark beetle. The ophiostomatoid fungi were represented...
