  1. Pheromones characterized (1950’s) Pest management devices Pheromones traps Pest monitoring devices

  2. 45 Different designs • Conventional market traps vs. new designs • Our new designs are playing around with: • different shaped traps • different size traps • different materials used to make a trap • Provisional patent: February- 2002 • Formal patent: January- 2003

  3. Anecdotal information • Current market traps- 10-25% • Trap design? • Sticky substance? • Pheromone lure? • Location?

  4. Influence of trap design and location on the capture of Plodia interpunctella (Indian Meal moth) (Lepidoptera: Pyralidae) in a release-recapture study J. stored Prod. Res. 34(1):33-36 (Mullen et al., 1998) • Mass trapping (36 traps in a warehouse) • No indication of how a single trap performs • Five different traps were used • Location was a factor in trap catch • ~72% of the males captured

  5. Over half the moths caught without a pheromone lure

  6. Difference = 16.4 percentage points

  7. Difference = 27 percentage points

  8. Forelegs make first contact rotation

  9. 90% caught in a trap 10% escape X Survive to reproduce

  10. 90% caught in a trap 10% escape

  11. Healthy moths trapped Generally unfit Unfit progeny

  12. Healthy moths trapped 10% escape Semi-Healthy moths trapped

  13. Experimental chamber “Hanging” trap “Floor” trap 20%
