Pecan weevil

Curculio caryae

Pecan weevil (Curculio caryae) is an insect pest of pecan and hickory trees. It was first detected in Virginia in 1992.

Pecan weevils cause serious damage to pecan crops. Feeding during early nut production hardening causes damaged nuts to drop. The most serious damage is caused by weevil larvae feeding on developing kernels.
