Start Date: May 01, 2011
End Date: Apr 30, 2013
Orchards with known leafroller populations will be identified in the Wenatchee and Yakima Valleys. Blocks will be monitored with traps baited with acetic acid and pear ester. Leafroller larval populations and fruit injury will be sampled and correlated with moth catches. Replicated trials will be conducted in a few sites to compare the attractiveness of several different host plant volatiles plus acetic acid.
