Spotted Wing Drosophila Management

8/25/2016

0 Comments

 
Spotted wing drosophila pressure is high this time of year with primocane raspberry harvest in full swing under high tunnels at the Michigan State University research site. To manage SWD, it's important to pick ripe fruit frequently and also to remove and dispose of any unmarketable fruit, including any berries on the ground. Unmarketable fruit is collected and disposed of in a sealed plastic bag left in the sun to heat up thus preventing any SWD eggs and larvae present from developing into adults. This practice, along with daily picking has kept SWD larvae numbers minimal.​
