Test arenas and corrugated cardboard traps were used to test attractive properties of synthetic pheromone, (4S,5R)-sitophinone, and various foods to rice weevils, Sitophilus oryzae (L.), in laboratory and in storage room. Cracked corn, rice kernels and corn germ oil trapped significantly more insects than 1 mg of (4S,5R)-sitophinone. A strong synergistic effect between the pheromone added with cracked corn or rice kernels or corn germ oil was demonstrated. Rice weevils were successfully lured out of a food source when cracked corn and (4S-5R)-sitophinone were present in the traps. A new design of corrugated cardboard trap was reported
