Intense armyworm infestations continue to consume pastures and hay meadows, but there's no indication that population counts are any larger than in previous years, according to a Texas AgriLife Extension Service expert.

"I don't think they're worse, but it's probably more intense (sudden) onset," said Allen Knutson, Ph.D., AgriLife Extension entomologist.

Substantial rains, like those much of the state has recently had from hurricanes and tropical storms, often trigger armyworm outbreaks, he said. The perception that armyworms are worse this year is probably because dry weather seems to inhibit their reproduction.
