Abstract： The insecticidal activity of 1.0% osthole powder and its influence on activity of CarE, AchE, GSTs and proteins of Sitophilus zeamais Motschusky was studied. The results showed that 1.0% osthole powder had strongly insecticidal bioactivity against S. zeamais. The corrected mortality of S. zeamais aduls were 100% after 3 days treatment over the dosage 0.8 mg/kg. After treated with 0.19 mg/kg in 2 days, the activities of CarE, AchE and proteins in S.zeamais were decreased, whereas the activity of GSTs was induced.
