Four types of traps baited with synthetic aggregation pheromone were tested in fields to catch the bean bug, Riptortus clavatus (Thunberg). Among them, a fence-like trap using a plastic net (W240×H100cm) with a water-pan caught the bugs much more effectively than a conventional water-pan trap (40cm in diameter). A simple ‘light trap’ made by replacing the light source with the pheromone, caught the bugs as well as the water-pan trap. The other two types might not be useful because few or no bugs were caught.
