Scientists in Oregon are forming a "swat" team to combat a pest that could cause $20 million worth of damage to the state's blueberry, blackberry, raspberry and cherry crops alone.

The spotted wing Drosophila suzukii, also called a vinegar fly, already has spread to 15 Oregon counties, KVAL-TV, Eugene, Ore., reported.

The fly arrived in California two years ago, scientists said in the report, most likely with a fruit shipment from East Asia. It made its way to Oregon last summer.

Plans to control the pest likely will include sanitation measures by growers, chemical spraying and mass trappings, the TV station reported.
