摘　　要：应用 5种植物粉剂和 5种食用植物油分别对两种重要储粮害虫谷蠹 (Rhizo pherthadominicaFab .)和长角扁谷盗 (Crplolestespusillus (Schonherr) )进行了药效试验 ,结果表明 :菜籽油和大豆油以 4 .0mL/kg拌和稻谷对这两种害虫的防效在 3周内均达到 90 %以上 ,而以 10mL/kg剂量在 10天即可达 97.5 %～ 10 0 % ;2 .0mL/L的大豆油和玉米油对谷蠹的熏杀效果在 72小时内均达 98.6 % ,对长角扁谷盗可达 10 0 %。 2 .0‰w/w的胡椒粉、五香粉和辣椒粉对长角扁谷盗的防效分别为 84 .6 % ,92 .5 %和 10 0 %。The toxicity of five kinds of botanical powder and five kinds of edible vegetable oils against Rhizophertha dominica Fab and Cryplolestes pusillus (Schonherr) were tested respectively.The results showed that the rapeseed oil and soybean oil at dosage of 4mL/kg can control the two insect species with the mortality above 90% within three weeks.While mortality can reach from 97.5% to 100% atdoseage of 10mL/kg within ten days.The soybean oil and corn oil can kill 98.6%for R.dominica and 100% for C.Pusillus within 72 hours.2.0‰w/w of pepper powder,spice and red pepper powder can kill C.Pusillus, the mortality was 84.6%,92.5% and 100% respectively.
