Effects of Color and Trunk-wrap on Pecan Weevil Catch In Pyramidal Traps

Pyramidal traps of various colors and trunk-wraps of white plastic and whitewash were evaluated to optimize pyramidal traps for collection of pecan weevils, Curculio caryae (Horn). Black traps were superior to all other colors tested and are recommended for use by growers. White plastic wrap was as effective and easier to use than whitewash and both increased trap capture (white plastic 2.8, whitewash 1.8 fold) of pecan weevils.
