SUMMARY: Bark beetles play important role in various types of forest
ecosystems. Though they are secondary in their capability to attack forest
trees, when favourable conditions occur they can build massive outbreaks and
cause significant damage. Croatian foresters have used all available 1PM
measures including world-wide use of pheromones for monitoring and suppressing
outbreaks of most important conifer bark beetle species. Explanation of
chemical stimuli communication among bark beetles is given in this paper.
Basic designs and most widely used pheromone traps in Croatia are funneltraps
based on Bakke´s trap. Hollow rectangular traps (Theysohn) are sometimes
also been used. Fundamental data on managing pheromone traps for three
bark beetle species is given in a tabular way. Being species-specific in their
activity, pheromone traps have certain drawbacks in forest protection measures
because they trace only several nowadays important pests. This is why classical
methods (trap log fellings) should not be abandoned but used together with
modern pheromone techniques in future.
