A Pocket Guide to IPM Scouting in Highbush Blueberries

This compact guide contains pictures and short descriptions of blueberry pests and disorders as well as other useful information for blueberry growers and consultants. 

The guide covers many IPM issues including insect and mite pests, natural enemies, diseases, and physiological and chemical disorders. The guide also discusses general directions for the timing of pest scouting and shows the main blueberry growth stages.

Biology and management of stem gall wasp in highbush blueberries

 Blueberry stem gall wasp, Hemadas nubilipennis, is an insect pest that attacks highbush and lowbush blueberries. This species can be found on wild blueberries growing in natural areas, but it has historically been only an occasional pest of commercial blueberry fields. More recently, stem gall wasp has become a significant pest in some regions of commercial blueberry production. To help growers manage this insect, we have prepared this summary of its biology and management based on recent research. 

Management Recommendations for Spotted Wing Drosophila in Organic Berry Crops

Michigan State University is collaborating with researchers from across the country to address the invasive insect pest, spotted wing Drosophila (SWD). This pest is particularly challenging for organic growers due to the limited number of organically approved and effective insecticides. With funding from the USDA National Institute of Food and Agriculture Organic Agriculture Research and Extension Initiative (OREI), the team has been investigating behavioral, cultural and chemical management strategies for this pest. Results from those studies have been combined with other experience managing SWD to develop “Management Recommendations for Spotted Wing Drosophila in Organic Berry Crops.” Using a range of control techniques will help to reduce SWD infestation.
