Brian Lehman presented this in December 2010 at the Cumberland-Shenandoah Fruit Workers Conference.

1. A Redesigned Electronic Insect Trap for Automated Monitoring of Lepidoptera in Orchards Brian L. Lehman (PSU) Larry A. Hull (PSU) Johnny Park (Purdue University) German Holguin (Purdue University) Teah Smith (Washington State University) Vincent P. Jones (Washington State University) CSFWC - 2010 B. Lehman/L. Hull - PSU

2. Prototype Digital Trap - 2009 CSFWC - 2010 B. Lehman/L. Hull - PSU

3. Moth trapping issues in 2009 Electronic traps had poor capture rates compared to large plastic delta traps. Vapona® strips likely had repelling effects. Repelling effect of ultrasonic waves emitted from electronics ruled out. Electronic traps often recorded false capture events. CSFWC - 2010 B. Lehman/L. Hull - PSU

16. CSFWC - 2010 B. Lehman/L. Hull - PSU Funnel experiment to determine moth escape rates

17. Percent of moths escaping CSFWC - 2010 B. Lehman/L. Hull - PSU * Percent moths escaping out of five moths (cm) and ten moths (ofm) per day over a four day (cm) and three day (ofm) period.

18. Trap designed with baffle to prevent moths from escaping CSFWC - 2010 B. Lehman/L. Hull - PSU Jones and Smith, 2010. WSU – unpublished data

19. Future electronic trap plans Redesign Z-trap exterior to increase moth capture rates Design trap with modular components so they can be easily modified for specific insects and/or conditions Modify IR traps to increase capture rates Possibly incorporate Z-trap and IR trap into one trap design Further analyze electronic signals from different target and non-target species Develop a user interface that works in conjunction with wireless communication and automatically displays trap location, insect detections for individual traps, and graphs of cumulative insect detection B.
