We conducted field and semi‐field experiments to determine the most visually stimulating and acceptable version of a branch‐mimicking trap (PVC cylinder topped with an inverted screen funnel) to capture adult plum curculios, Conotrachelus nenuphar (Herbst) (Coleoptera: Curculionidae) foraging within canopies of host trees. Cylinder traps ( 25 cm tall × 6 cm diam ) coated with different colors of gloss or flat latex paint captured similar numbers of feral adults in field tests. Tall cylinder traps ( 50 cm tall × 6 cm diam ) captured significantly more feral adults in field tests in 1999 than cylinder traps of lesser height and/or different diameter, and significantly more released adults arrived at traps with these dimensions compared to cylinder traps of lesser height in semi‐field tests. In field and semi‐field tests, respectively, significantly more adults were captured by and numerically more adults arrived at tall cylinder traps ( 50 cm tall × 6 cm diam ) attached in an upright, standard position to a horizontal limb than attached at angles of 45°, 90°, 135°, or 180° to horizontal limbs.
