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

  19. 19. Future electronic trap plans<br />Redesign Z-trap exterior to increase moth capture rates<br />Design trap with modular components so they can be easily modified for specific insects and/or conditions <br />Modify IR traps to increase capture rates<br />Possibly incorporate Z-trap and IR trap into one trap design<br />Further analyze electronic signals from different target and non-target species<br />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<br />B.
