The tree decline as a key problem Tree Forest stand Forest ecosystem STRESS INJURIOUSFACTORS FOREST DECLINE

The key approaches... caused by weather anomalies, emissions, wind, snow, insects, fungi infections etc. results in the decline of commercially and ecologically important forest tree species. Natural forests are more pest resistant. Have a close nature forest - have a healthly forests General decrease of the vitality and stability of forest stands

Injurious factors  Biotic agents phytopathogenic micro-organisms, insect pests bark beetles and wood borers, leaf-eating and sucking, insects, game  Anthropogenic injurious factors air pollution, immissions, other anthropogenic injurious factors  Abiotic injurious factors weather anomalies, wind, snow, frost, dry... synergistic effect

Injurious factors Proportion of incidental felling in total volume of felling in Slovakia (in %)

Injurious factors Damage caused by non-biotic injurious factors

The key approaches WHAT IS Integrated pest management ? It is a system of the different methods in silviculture, forest management and forest protection with target to prohibit forest from injury.

The key approaches WHY Integrated pest management ? We do not control one single agant but we are dealing with several agents which attack the forest in the same time or one after the other.

IPM rules Integrated pest management general RULES Economical Effective Ecological Different treatments have to by co-ordinated together. Make prevention instead of suppression or eradication.

IPM rules Integrated pest management general RULES Pest management has to be realised on a large (possible all) infected area. We do not need fully remove the pest from the ecosystem - we need to keep its population density under the economical (or another) level. Combination of mechanical, chemical and biological treatments.

Models Integrated pest management MODELS Basic information (tree, stands, soil, position, insect presence...) Simulation of possible combined effects of the injurious factors

Gypsy moth Lymantria dispar in Slovakia - population dynamic Forest pests

Gypsy moth Lymantria dispar in Slovakia Monitoring of population dynamic. Annual and regular monitoring system using pheromone traps. Monitoring of natural enemies complex. In were two egg parasitoids Ooencyrtus cuvanae and Anastatus disparis introduced from south Europe into the south Slovakia. They were successfully established in Forest ecosystems. Monitoring of parasitoids and predators through different projects.

Forest pests Gypsy moth Lymantria dispar in Slovakia Criteria for area applications -in high quality production forests, forests close to urban area, forest in central part of gradation area, places with low population density of natural enemies... Pesticides aplication on large area only.

Results Conclusion The are no principle differences between IPM in normal managed forest and in nature close forest. Theoretical knowledge about IPM has to by implement directly in to the praxis and applied in the close nature forests.....thank you for your attention!
