Jim McGlone from the Virginia Department of Forestry talks about using sustainable landscaping to manage pests.

Integrated Pest Management is a sustainable approach to managing pests by combining biological, cultural, physical and chemical tools in a way that minimizes economic, health and environmental risks.

This presentation was given at The Piedmont Environmental Council's Sustainable Landscaping Workshop on August 29, 2015 in Warrenton, VA.

Sustainable Landscaping as an Integrated Pest Management (IPM) Tool

  1. 1. Sustainable Landscaping as an IPM Tool Jim McGlone Virginia Department of Forestry
  2. 2. What is IPM? IPM is a sustainable approach to managing pests by combining biological, cultural, physical and chemical tools in a way that minimizes economic, health and environmental risks.
  3. 3. Gardens are Ecosystems • Components: – Living – plants, animals (including insects), bacteria, fungi – Non-living – mineral, water, air, light – Interactions between and among the living and non-living
  4. 4. THE ROLE OF INSECTS - FEEDING
  5. 5. Herbivores • Leaves • Flowers • Stems • Roots
  6. 6. Pollinators
  7. 7. Recycling
  8. 8. Seed Dispersal
  9. 9. Predators/Parasites
  10. 10. Pests • Insects have a role in the garden • Pests get out of check • Need to have some around to keep predators and parasites in the garden • Without ‘carnivores’ we are left with only chemicals
  11. 11. THE ROLE OF PLANTS - HABITAT
  12. 12. Habitat • Food • Nesting • Resting • Water • Plants form niches • Native plants have higher levels of interactions with native insects
  13. 13. NESTING
  14. 14. RESTING
  15. 15. Over Wintering
  16. 16. HOW TO GET THERE - DIVERSITY
  17. 17. Horizontal Diversity
  18. 18. Horizontal Diversity
  19. 19. Vertical Diversity
  20. 20. Temporal Diversity
  21. 21. Many flower flies are pollinators as adults and aphid hunters as larvae.
  22. 22. Butterflies and Moths Adults will feed on any flower, caterpillars are usually picky.
  23. 23. Key Points • Increasing plant diversity increases insect diversity, including predators • Diversity means horizontal, vertical, and temporal • Use native plants –avoid cultivars, especially those that change shape and/or color of flowers. • Leave some bare ground for bees • Keep dead stems and leaves in or near garden
  24. 24. How do I know this works? • WWMND? – What would mother nature do? • All pictures were taken in my yard. • Dr. Michael J. Raupp studies on plant and insect diversity in landscapes.
