Improving Your Wild Blueberry Yields – Pest Insect Control

Although controlling the damage from pest insects will not increase your yields, not preventing the damage can result in yield losses or your berries being rejected because of wild blueberry maggot. Research done at the University of Maine has identified action thresholds or numbers of insects that would cause economic damage to your crop and reduce your yields. You will need to scout your crops to look for damage – use a sweep net or trap to determine which insect pest you have and if the numbers warrant treatment. Fact Sheet 204, Integrated Crop Management Field Scouting Guide for Lowbush Blueberries on how and when to scout your crops.

July is the month to begin monitoring for the blueberry maggot fly to prevent infestation, see Fact Sheet 201, Monitoring for the Blueberry Maggot, maggot/ and this year we have a new pest the Spotted Wing Drosophila which requires a different kind of trap. See

Control measures to prevent damage may be found in Fact Sheet 209, 2012 Insect Control Guide, Preventing damage early will maintain the gains that you have made and prevent yield losses.
