Orchard Biological Control

A multi-state, multi-agency SCRI project

spacer Ascogaster quadridentata" id="wows0"/>This small, but highly efficient parasitoid lays an egg inside a codling moth egg. Secondary hosts include OFM and LAW eggs. spacer Colpoclypeus florus" id="wows1"/>This ectoparasitoid attacks leafroller larvae older than 3rd instar. spacer Colpoclypeus florus" id="wows2"/>C. florus is a gregarious ectoparasitoid, meaning that several offspring develop on a single host larva, in this case a Pandemis leafroller. spacer Mastrus ridibundus" id="wows3"/>This parasitoid attacks cocooned last instar codling moth larvae. spacer Tachinids are a large group of natural enemies with more than a 1000 species in North America and have a broader host range than parasitic wasps. spacer This tachinid fly is very adapt at locating host larvae in orchards.

Welcome!

spacer Enhancing Western Orchard Biological Control (EWOBC) is a collaborative SCRI project between Washington State University (lead institution), USDA-ARS, Oregon State University, and the University of California at Berkeley. The team is focused on ways to improve the stability of IPM programs in apple, pear, and walnut orchards, by enhancing biological control. Our team includes six entomologists, an insect geneticist, an economist, an extension specialist, and a sociologist.

Short Course

A 2-Day interactive short course about natural enemies and novel tools to maximize biological control was held Washington and Oregon in February 2012. For those that missed this event, the workbook is now available to download. Although focused on apple and pear orchard systems, the information presented in the course content is relevant to most perennial cropping systems. more info>>
