Spotted wing Drosophila meetings scheduled for August 30 in east Michigan
Fall red raspberry and blueberry growers are seeing high spotted wing Drosophila trap catch numbers and a few are seeing wormy berries.
In the last week, many fall red raspberry and blueberry farms in east Michigan have had very high trap catch of spotted wing Drosophila. This new invasive pest has the potential of causing small, white larvae or worms in fruit at harvest time. In fact, a few farms have had to stop harvest in the last week due to finding wormy berries.
In response to these events, two quick grower meetings are scheduled for Thursday, August 30, with the goal of helping educate growers to trap, identify and control this pest. Michigan State University entomologist Rufus Isaacs will be sharing his expert knowledge of this pest and his hot-off-the-press research findings as to the best materials to gain control of this pest. Both of these two-hour meetings will have the same agenda with some time gathered around picnic tables and time in the berry field as well. There is no charge for these meetings.
This is a busy time of the season for berry growers as blueberry harvest is just finishing and fall red raspberry harvest is just ramping up. The timing of these meetings will hopefully allow growers to break away from the farm for a short time and then get back in time to keep things rolling along.
