ST. LOUIS (DTN) -- An Old World agricultural pest has officially invaded U.S. territory, and experts say a future invasion of the U.S. mainland is probably unavoidable.

Helicoverpa armigera, known as the Old World bollworm, was detected in the U.S. territory of Puerto Rico in September 2014, an alarming advance that signals a likely U.S. invasion of the pest, government and academic experts have concluded.

"This is a significant event," Louisiana State University entomologist David Kerns told DTN. "Honestly, it's just a matter of time; if it's in Puerto Rico, we're going to have it soon, if we don't already."
