The pecan weevil, Curculio caryae (Coleoptera: Curculionidae) is an obligate feeder on the nuts of North American hickories and pecans (Carya species), most widely recognized as an economically important pest of the pecan, Carya illinoinensis (Fagales: Juglandaceae). It has also been observed to infest one Juglans species, the Persian walnut, Juglans regia. Their economic importance results from crop loss due to their feeding and egg laying on the developing pecan nuts causing them to drop from the tree, and the destruction of the edible nut kernel by the larvae feeding inside the shell.
