【摘要】 选取三峡地区18种药用植物的甲醇提取物对赤拟谷盗进行生物活性研究,结果表明:处理72h后,独角莲、独活提取物(629цg/cm~2)对赤拟谷盗成虫有较强的触杀作用,校正死亡率独活为74.54%,独角莲为60.66%;黄姜叶、黄姜根、乌头、透骨草对赤拟谷盗成虫的驱避作用较强,处理72h后的驱避率均在88%以上;透骨草提取物对赤拟谷盗种群有很强的抑制作用,在400mg/kg～1600mg/kg浓度下,种群抑制率达72.30%～100.00%,对叶百部、独活在1600mg/kg浓度下,种群抑制率依次为88.02%、62.41%。更多还原

【Abstract】 In this paper the bioactivity of the methanol extracts of 18 kinds of plants on Tribolium castaneum Hberstare studied. The results indicate the contact effects of the extracts of Typhonium giganteun Engl. and Heracleum L. on theadult is obviously after 72 hours of treatment. And the revised death rate of the two extracts are 74.54% and 60. 66% re-spectively The rejective results of Doscoreaceal zingiberensis C. H. Wright. Sinomontunum L.Phryma leptostachya L.var. asiatica on the adult are more than 88% within 72 hours after treatment. The effect of the extracts of Phryma lep-tostachya L.var. asiatica to the population is obviously. The inhibition rate of the species arranged from 72.3% to 100%under the concentration of 400ppm to 1600ppm. The inhibition rate of the species of the extracts of Stemona tuberosa Lourand Heracleum L.under the concentration of 1600ppm are 88.02% and 62.41% respectively.更多还原
