The leek moth invasion: A monitoring program detailing the current and potential distribution of leek moth within Vermont and New York

Leek moth, Acrolepiopsis assectella Zeller, is a recently introduced invasive pest severely affecting allium production in Vermont and adjacent states. It is known to be responsible for damage leading to significant economic injury for farmers. Considering the pest’s increasing distribution within the region, losses associated with pest are projected to increase considerably as the current invasion progresses. Though the pest’s documented distribution includes Ontario, New York and Vermont, its potential distribution is extensive and wide-ranging. According to the 2012 agricultural census, 120 farms within Vermont currently grow allium crops. Alliums cumulatively represent the 8^th largest vegetable crop by acreage and 10^th in number of Vermont growers.  This study documents our current monitoring program and details the current and potential leek moth distribution throughout New York and Northern Vermont. This monitoring program provides critical information for implementing effective cultural and chemical control tactics and aids in the continued development of new sustainable methods of pest management.
