Another TMG Winter School alert: an invasive fruit fly
Warning: this is so gross
Dr. Frank Hale from UT Extension told us about SWD. Drosophila suzukii, the Spotted Wing Drosophila (SWD) is native to southeast Asia. It was first spotted in California in 2008. Since then, it has been detected in Washington, Florida, Utah, Michigan, Wisconsin, Kentucky, Louisiana and - in 2011 - in Unicoi County in Tennessee. This nasty little critter lays eggs in fruit crops. Strawberry, blueberry, grape, cherry, apple, fig, you name it.
|Adult Female - note ovipositor|
|Adult Male - spotted wings|
|Egg-laying holes in blueberries|
|Pupae in blueberries|
We should warn our grower friends about this pest. They should make traps and put them out at least 2 weeks before the fruit will be ripe. Learn how to make a trap here.
