The effect of food source in aggregation pheromone trap of bean bug, Riptortus clavatus, was evaluated in terms of the trap attractiveness using water-pan and cylinder-type traps. Water-pan trap baited with pheromone+food (dried soybean+dried peanut+water) attracted significantly more number of females and males than those with pheromone or control trap. Although cylinder-type trap baited with pheromone+food did not show significantly higher attractiveness, it attracted more adults and nymphs than the pheromone and control traps. Further research on the effect of trap types on attractiveness is needed.
