Homeowners and pecan orchard operators are urged to watch for pecan weevils that can decimate a crop right up to harvest.
“This is not a new pest, but what is new is that it’s being sighted in areas where it’s never been found,” said Bill Ree. “It’s a serious pest, ranking right up there with the ubiquitous casebearer that hits developing pecans early in the season practically statewide. Pecan weevils hit late in the season when the nuts are ready to be harvested. “What’s troubling is we are seeing a considerable geographic movement in a pest that was once fairly isolated. We are confident this migration is human-assisted.”
Pecan weevil, Curculio caryae, is a native to North America, and has been collected from all the native hickory species, though detailed knowledge of its distribution is only known within pecan populations, Ree said.
