摘　　要：以2%辣椒素乙醇溶液均匀喷雾添加于糙米,研究辣椒素对储粮害虫玉米象和赤拟谷盗的拒食和增殖作用。结果表明:辣椒素添加量为4,2g/kg.糙米时,玉米象和赤拟谷盗表现出明显的拒食现象,30d内糙米的因虫损失率,玉米象两个浓度处理组仅为空白对照的26.4%和35.4%;赤拟谷盗处理组仅为空白对照的24.8%和30.6%;辣椒素的添加剂量为0.5g/kg.糙米时,玉米象组、赤拟谷盗组增殖数量分别为空白组的9.23%,26.1%;辣椒素的添加剂量为2g/kg.糙米时,玉米象组存活数仅1头,赤拟谷盗存活数为0。辣椒素的添加使玉米象和赤拟谷盗的增殖受到了明显抑制。With 2% capsaicin ethanol solution sprayed on cargo rice evenly,the effect was studied of capsaicin in Sitophilus zeamais and Tribolium castaneum preventing for grain storage.The results showed that according to the ratio of capsaicin to cargo rice 4 g/kg and 2 g/kg,Sitophilus zeamais and Tribolium castaneum appeared distinctly refusing feed effect.The damage rate of cargo rice in 30 days caused by Sitophilus zeamais were only 26.4% and 35.4% to that of blank controls,similarly Tribolium castaneum caused damage rate only 24.8% and 30.6% to that of blank controls.The reproduction number caused by Sitophilus zeamais and Tribolium castaneum was only 9.23% and 26.1% of blank control,according to 0.5 g capsaicin per 1 000 g cargo rice.When adding capsaicin 2 g per 1 000 g cargo rice,Sitophilus zeamais lived only 1 and Tribolium castaneum zero survived.The result showed that capsaicin had obvious reproduction effect on tested pests.
