Wl. Tedders et al., EFFECTS OF COLOR AND TRUNK-WRAP ON PECAN WEEVIL CATCH IN PYRAMIDAL TRAPS, Journal of entomological science, 31(4), 1996, pp. 414-419
Pyramidal traps of various colors and trunk-wraps of white plastic and
whitewash were evaluated to optimize pyramidal traps for collection o
f 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 bot
h increased trap capture (white plastic 2.8, whitewash 1.8 fold) of pe
can weevils.
