2011 ORGANIC BLUEBERRY INSECT MANAGEMENT PROGRAM INCORPORATING SWD CONTROLDOWNLOAD FILE
May 1, 2011 - Author: MSU Extension
We have developed this short document to assist certified organic blueberry growers and those with interest in organic approaches as they consider how to adapt their IPM program for the arrival of SWD. At the end of the document we provide an overview of potential organic pesticides that may be considered if trapping and monitoring information warrants this approach.
There are a handful of insect pests to scout for with potential to cause direct damage and/or infestation of blueberries in the Great Lakes region. These are cranberry fruitworm, blueberry maggot, Japanese beetle, and spotted wing Drosophila. There may be other insects that pop up during the season, but these four pests should be the focus of your organic IPM planning since they are direct pests of the fruit. Secondary pests of blueberries include aphids, gall midges, scales, mealybugs, mites, and leaf rollers. These pests are often kept at levels below any economic impact by natural biological control in organic plantings.
