Biology and Management of the Pecan Weevil (Coleoptera: Curculionidae)

Abstract

The pecan weevil, Curculio caryae (Horn), and its primary host, pecan, Carya illinoinensis (Wagenheim) K. Koch are indigenous to North America east of the Rocky Mountains. This review is presented to describe the biology, life stages, crop injury, monitoring approaches, and primary control strategies currently used for pecan weevil in pecan. Suggested economic thresholds are extrapolated from several sources and the utility of current monitoring information is presented to aid in management and quarantine decisions.
