Western bean cutworm (WBCW) has been on the move again, infesting cornfields in new territories. Growers in Illinois, Indiana, Iowa, Michigan and Wisconsin have experienced the devastation of WBCW for the past several years, and some areas in Ohio saw egg masses and larvae in fields for the first time this season. Entomologists predict pressure from the insect could only increase in the coming years in eastern Corn Belt states.

"If WBCW follows the same trend it has in other states like Michigan and Indiana, growers in Ohio can expect to see economic damage from the insect in the next couple of years," said Andrew Michel, entomology professor at The Ohio State University. "Usually you'll see scattered damage before economic damage."
