Monitoring adult populations of omnivorous leafroller with BioLure® pheromone traps is strongly recommended to provide baseline information on population density and to improve timing of mating disruption and/or insecticide treatments. Good monitoring is an important part of achieving optimum results. Visual inspection of leaves and fruit for larval feeding is also needed at frequent intervals after treating to implement supplemental control strategies if needed. Place one BioLure OLR wing trap per 10 acres with a minimum of two traps per block. When the first omnivorous leafroller is caught in a trap, CheckMate OLR-F should be applied. Note: Pheromone baited traps must be removed from the area to be treated before spraying and repositioned or replaced with new traps after every CheckMate OLR-F application. Place additional traps on borders that are most subject to migration from adjacent fields or host crops. Clean traps at least weekly. Replace BioLure OLR lures at least every eight weeks and traps more often if they become dirty or covered with dust, spray material, moth scales or other insect body parts. Do not handle other types of insect lures before or after placement of BioLure OLR traps without thoroughly washing hands. BioLure OLR traps should not be utilized as the only method of monitoring the degree of crop protection being afforded by CheckMate OLR. Effective pheromone mating disruption treatments will shut down trap catches of male moths. Pheromone lures, such as BioLure OLR will not detect migration of omnivorous leafroller females from adjacent fields or infestations of raisin moth.
