Feeding behavior, thresholds, and pheromone trapping of Campylomma verbasci

Summary: The objectives of this project were: 1. Modify and validate fall pheromone trap sampling as a method of identifying high-risk orchards for spring sampling (‘Delicious’ and ‘Golden Delicious’). 2. Determine the relative susceptibility to C. verbasci damage of apple cultivars other than ‘Delicious’ and ‘Golden Delicious’. 3. Develop provisional treatment thresholds on susceptible apple cultivars that currently have none.
