Research Topics
Our lab develops IPM strategies for pests of tree fruit. Current projects focus on pear psylla (pear), leafhoppers (cherry), spotted wing drosophila (cherry), and codling moth (apple and pear). We also have initiatives related to better understanding and improving Extension and outreach.
