Spotted Wing Drosophila Organic Managment Methods

POSTED IN For Growers, For Members ON 7/13/2018

Spotted Wing Drosophila (Male)

In this blog we have previously discussed Spotted Wing Drosophila (SWD), an invasive, relatively new fruit fly overspreading North America.  While there are few reported cases of SWD affecting saskatoon berries, there is broader concern for many fruits. Therefore, we are sharing this article suggesting that there is good news regarding organic management methods for SWD. Rufus Isaacs has addressed Institute members on several other pests, but none that present such a fast growing threat to fruit crops as SWD.

While most fruit flies are only interested in fruit still hanging from bushes and trees, SWD seem content to continue their lifecycle in fallen and rotting fruit as well. So while some USDA practices call for allowing fruit to drop, this fiend uses such situations to its benefit.

It is our hope that our friends across both the US and Canada can take note of these new developments, and be encouraged as they pursue some of these methods.
