Abstract: In first, preliminary experiments, the efficacy of the Czech Beauveria bassiana product "Boverol" alone and in combination with pheromone traps on the mortality and the breeding behaviour of the bark beetle, Ips typographus, was investigated. Pathogenicity tests resulted in a mortality due to the fungus of 88.0 to 96.7%. When the beetles were given directly after superficial contamination on fresh spruce pieces with bark, the reduction of the breeding efficacy was 23 to 29% compared to the untreated control. No differences between the hatched beetles from the F1-generation of contaminated beetles and those of the untreated control beetles were observed. A transfer of the fungus from the parent beetle to the young beetle was noticed only in a few cases. In the field, the efficacy of a combination of a pheromone trap with B. bassiana was tested. The number of bore holes and the breeding was measured using a caged spruce log. In the combination, the number of bore holes was reduced by 15%, but the F1 generation nearly, by 60%. Possible strategies for the use of B. bassiana in combination with pheromone traps against Ips typographus are discussed.
