Abstract
Rice plant volatiles extracted as steam distillates significantly affected the behavior of the rice leaffolder,Cnaphalocrocis medinalis (Guenée). Leaffolder moths laid significantly fewer eggs on TN1 rice plants treated with extracts of resistant wild species of rice,Oryza officinalis andOryza punctata, than on TN1 plants treated with extracts of resistant cultivated rices. Extracts ofO. officinalis andO. punctata adversely affected egg hatchability.O. officinalis andO. punctata extracts were more toxic to first-instar larvae than extracts of other resistant varieties. Leaf area consumed by the larvae was reduced on TN1 plants treated withO. officinalis andO. punctata extracts compared with that on plants treated with extracts of resistant cultivated rice varieties.
