1. Integrated pest management in close nature forestry • Prof. Dr. Július Novotný,CSc. • Dr. Milan Zúbrik • Forest Research Institute Zvolen, Research Station B. Stiavnica, Lesnícka 11, 969 23, Slovak republic

2. The tree decline as a key problem INJURIOUS FACTORS STRESS Tree Forest stand Forest ecosystem FOREST DECLINE

3. General decrease of the vitality and stability of forest stands 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

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

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

6. Damage caused by non-biotic injurious factors Injurious factors

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

8. WHY Integrated pest management ? The key approaches 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.

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

10. Integrated pest management general RULES IPMrules • 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.

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

12. Integrated pest management MODELS Models • Models for ecosystems (mountain forests, nature reserve) • Models for tree species (spruce, beech...) • Model contents • risk factors • treatments in prevention • treatments in suppresion

13. Bio agents -leaf eating insect Forest pests Hmyz huby • Gypsy moth (Lymantria dispar) • Tortricids on oak (Tortrix viridana, Aleima loenflingiana...) • Geometrids on oak (Erannis defoliaria, Operophtera brumata) • Silver fir woolly aphid (Dreyfusia nordmannianae) • Melolontha sp.

14. Forest pests Forest area defoliated by leaf eating insect during last 10 years period in Slovakia

15. Gypsy moth Lymantria dispar in Slovakia - area Forest pests

16. Gypsy moth Lymantria dispar in Slovakia - population dynamic Forest pests

17. Gypsy moth Lymantria dispar in Slovakia Forest pests • Monitoring of population dynamic. • Annual and regular monitoring system using pheromone traps. • Monitoring of natural enemies complex. • In 1960-65 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.

18. Gypsy moth Lymantria dispar in Slovakia Forest pests • 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.

21. Gypsy moth Lymantria dispar in Slovakia Forest pests • SIT • ULV treatments -2-4 l/ ha • Only viruses or B.t. pesticides used. • In 1994-1995 was Foray on area of 5000 ha applied.

22. Bio agents -bark beetles and wood borers Forest pests • Ips typographus • Pityogenes chalcographus • Ips sexdentatus • Ips acuminatus • Scolytus intricatus

27. 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!
