The nursery industry has a large economic impact in the state of Kentucky.  A report from the Kentucky Horticulture Council states that in 2012, cash receipts for wholesale and retail sales for nursery, greenhouse, and sod products totaled between $50 and $70 million.  In 2015, Kentucky had 515 licensed nurseries in the state (data from Office of the State Entomologist).

Many moth pests attack popular trees and ornamentals that are sold in Kentucky’s nurseries.  This trapping survey will safeguard this economically important industry and will augment yearly inspections by nursery inspectors from the Office of the State Entomologist at the University of Kentucky.

For the insect portion of the nursery survey in 2010 and 2011 we set 3 different moth traps in 20 nurseries. Each trap targeted a different moth pest of concern: Summer Fruit Tortix, False Codling Moth, and Egyptian Cottonworm.  One trap for each insect pest, baited with the appropriate lure, were in place from April/May to September/October in 2010 and 2011.

In 2016 and 2017, we set 5 different moth traps in 10 nurseries.  Each trap targeted a different moth pest of concern: Variegated Golden Tortrix, Oak Processionary Moth, Green Oak Tortrix, False Codling Moth, and Summer Fruit Tortrix.  One trap for each insect pest, baited with the appropriate lure, were in place from April/May to September/October in 2016 and 2017.
