摘　　要：研究了1.6%蛇床子素粉剂对谷蠹、米象、赤拟谷盗、嗜卷书虱等4种储粮害虫的室内防治效果。在按制剂量计算分别为25 mg/kg、50 mg/kg和75 mg/kg剂量下,1.6%蛇床子素粉剂对供试的4种储粮害虫均有显著的防治效果;其中对米象、赤拟谷盗和嗜卷书虱等3种试虫的作用迅速,施药7d后校正死亡率或虫口抑制率均达到了100%;而低浓度下对谷蠹的作用较为缓慢,25 mg/kg下14 d后校正死亡率才达到95%以上。The efficacy of 1.6% osthole powder to Rhizopertha dominica Fabricius, Sitopilus oryzae （Linnae-us）, Tribolium castaneum （Herbst） and Liposcelis bostrychophila Badonnel was researched. The results showed that at the dosage of 25 mg/kg, 50 mg/kg and 75 mg/kg respectively, 1.6M osthole powder had significant control effects to these four insect pests, and acted promptly to S. oryzae, T. castaneum and L. bostrychophila, the corrected mortality or the suppression rate after 7days to live pests all reached 100%. But it acted slowly to R. dominica at low concentration, the corrected mortality just reached 95 % at concentration of 25 mg/kg after 14 days.
