  1. Residual and Antifeedant Activity of Landscape Insecticides Against Japanese Beetles Rebecca Baumler, Bonny Miller, & Daniel A. Potter Department of Entomology “Fear No Beetle”

  2. Managing Adult Japanese Beetles In Landscapes

  3. Plant Selection is Priority 1!!

  4. Highly susceptible: Resistant: • Most lindens • Purple leaf plum • Sassafras • Norway maple • Roses • Certain crabapples • Roses • Hibiscus • Red maples • Most oaks • Flowering dogwood • Redbud • Beech • Hickory • Tuliptree • Sweetgum

  5. Traps contain two lures: a floral scent, and the female sex pheromone

  6. Traps were evaluated in home landscapes and on golf courses

  7. Professional / Homeowner

  8. “Homeowner” products tested • Neem-away® (azadirachtin) • Pyola® (pyrethrins + canola oil) • Hot Pepper Wax (capsaicin) • Surround® (kaolin clay particle film) • Rotenone/pyrethrins combo • Orange Guard® (limonene) • Garlic Guard® (garlic extract) • Sevin® (carbaryl)

  9. Tilia cordata (littleleaf linden) used for all trials

  10. Tagged shoots sprayed • Left in field to weather for intervals of 1 to 19 d • Shoots harvested, leaves challenged with JB

  11. Pyrethroids Provide at least 19 Days Control!

  12. Two of the “organic” products caused severe phytotoxicity: Orange Guard Garlic Guard

  13. Surround® (kaolin clay) did not deter feeding

  14. Untreated Neem-away Untreated Pyola

  15. Neem (Azadirachtin): Natural insecticide extracted from from seeds of a tropical tree

  16. Summary • Pyrethroids (DeltaGard, Talstar, Scimitar, Tempo) gave at least 19 days’ residual protection; longer than Sevin • Most “homeowner” organic products were ineffective • Pyola® (pyrethrins & canola oil) and Neem-Away® deterred feeding for 3-7 days.

  17. Support Provided By: • UK Nursery/Landscape Research Endowment Fund • USDA New Crops Opportunities Grant • US Dept. of Agriculture “Fear No Beetle”
