Bean bugs harm to almost plant like major food crops, fruit tree, flower and medicinal crops in the world. Among the rest, bean bugs damage to leaf, stem and seed in pulses crops. Adult males of bean bugs caused more damage by attract same species male and female adults, nymph. And their amount of aggregation pheromone secretion is affected by environment, season, physiological status and nutritive conditions. In this study, to know difference of aggregation pheromone secretion by feeding condition, we confirmed difference of pheromone secretion by each soybean cultivars on indoor breeding, and compared to bean bug received different feeding condition (seed only, plant only, seed and plant) on same cultivar. In addition, hairy vetch (Vicia villosa) that using green manure crop and be damaged by bean bug is added to this experiment, although they are unsuited for complete bean bug lifecycle. We found difference in amount of aggregation pheromone secretion at each soy bean cultivars, and bean bug received seed and plant together secrete higher than other bean bug received each seed and plant.
