IPM Message for Cranberry Growers: Apr 18, 2012

Apr 18, 2012

Winter moths are on the bog now! We now have over 12 reports of winter moth larvae found in sweep sets on sites throughout cranberry land. High counts of 15-30 were reported in Mattapoisett, Rochester, and Wareham. Several reports of 10 counts came from Plymouth sites. Other sweeps confirm counts ranging from 0-10, concentrated on the edge of the bog. Most infestations were on the edges rather than the middle but a few bogs had larvae throughout. The larvae are very small!! but they are out there. It would be wise to sweep your bog THIS WEEK to check for them. Blueberries around the bogs are loaded with winter moth larvae
