The sorghum plant bug is a major insect species causing pecky rice. The details of nymphal occurrence of this bug in rice paddy fields have not been investigated. To clarify the potential for nymphal development on rice plants, the development of nymphs reared on different foods was examined i.e., a rice seedling only, hulled rice only, and a rice seedling and hulled rice under laboratory conditions. The percentage of adult emergence was 96.7% and 76.7% for nymphs reared on a rice seedling with hulled rice and hulled rice alone, respectively, while no adult emergence was observed for nymphs reared on a rice seedling alone. No significant differences in either the developmental period of nymphs or the forewing length of emerged adults were observed between nymphs reared on a rice seedling with hulled rice and those reared on hulled rice alone. It was concluded that hulled rice is an appropriate food for nymphs. This suggests that the availability of grains on the rice plant affects nymphal development.
