What Is the Winsome Fly and Why Does It Matter on VegEdge?

Updated

The Winsome Fly is a beneficial insect that acts as a biocontrol agent against the Japanese beetle, and it is now naturally spreading in Minnesota. On VegEdge, it appears because the site covers integrated pest management (IPM) for vegetable crops in the Midwestern U.S., and the Winsome Fly is relevant to growers dealing with Japanese beetle pressure. VegEdge points readers to a new Winsome Fly fact sheet published on FruitEdge and notes an opportunity to join a Winsome Fly Citizen Science project.

What the Winsome Fly does

According to the VegEdge announcement, the Winsome Fly is a biocontrol agent of the Japanese beetle. In practical terms, that means it is a natural enemy that can help suppress Japanese beetle populations rather than relying only on chemical controls — which fits the IPM approach VegEdge is built around.

Where to find the Winsome Fly resources

VegEdge lists two specific resources tied to the Winsome Fly:

  • Fact sheet — A new beneficial insect fact sheet was published on FruitEdge. VegEdge links out to it directly ("View the fact sheet here").
  • Citizen Science project — VegEdge notes an opportunity to participate in a Citizen Science project led by entomologist Bill Hutchison.

Both items appear in the News & Pest Alerts section of VegEdge, alongside other updates such as the Weekly Vegetable Update.

Why this is on VegEdge

VegEdge provides timely, objective information about all aspects of vegetable crop IPM, with a focus on the Midwestern U.S., drawing on 25+ years of University of Minnesota research. Beneficial insects like the Winsome Fly are part of that IPM picture: they are a tool growers and crop consultants can factor into pest management decisions. The site also notes that the Winsome Fly is now naturally spreading in Minnesota, which makes it directly relevant to local growers rather than a purely theoretical option.

How to use this if you're a grower or consultant

  1. Read the fact sheet on FruitEdge to understand what the Winsome Fly is and how it relates to Japanese beetle management.
  2. Check the VegEdge News & Pest Alerts section for the original announcement and any follow-up updates.
  3. Consider the Citizen Science project if you want to contribute observations — VegEdge frames it as an open opportunity led by Bill Hutchison.
  4. Pair it with VegEdge's other IPM tools — the site also runs a Moth Flight Network (monitoring ECB and CEW moth catch statewide) and degree-day calculations for key insect pests, which support broader pest-timing decisions.

What VegEdge does not state here

The VegEdge page does not provide release instructions, application rates, or region-specific efficacy data for the Winsome Fly. For those details, the fact sheet on FruitEdge is the referenced next step.
