摘  要:
用鹿蹄草 (Pyroladecorata)的萃取物对玉米象 (Sitophiluszeamais)和谷蠹(Rhizoperthadominica)进行了毒力测定。测定结果为 :玉米象 y =1.9799x + 2 .976 1,谷蠹 y=1.74 0 7x + 2 .8173,加入增效醚后 ,玉米象 y =1.86 0 3x + 3.6 897,谷蠹 y =1.5 779x + 2 .875 1。实验结果表明鹿蹄草对以上两种害虫均有毒力 ,加入增效醚 ,对玉米象的毒力有所增加 ,但对谷蠹无显著变化。

摘  要:
xToxicity test of Pyrola decorata extract against Sitophilus oryzae and Rhizopertha dominica was carried out.The results showed that the probatility mortality regression lines for Sitophilus zeamais is y=1.9799x+ 2.9761 ,r=0.9560,LC 50 =10.5245g/L,95%confidence interval was 9.9027~11.1463g/L; Rhizopertha dominica is y=1.7407x+2.8173,r=0.9956,LC 50 =17.9432,95%confidence interval was 16.8153~19. 711g/L. In pyrola decorata extract adding intensive aether the probability mortality regression lines for Sitophilus oryzae is y=1.8603x+3.6897,r=0.9742,LC50=5.0617,95%confidence interval was 4.9399~5.1835g/L,for Rhizopertha dominica is y=1.5779x+2.8751,r=0.9867,LC 50 =22.2177,95%confidence interval was 20.2088~24.226g/L.It showed that the Pyrola decorata extract has effect,but this effect is not higher.In Pyrola decorata extract adding intensive aether,the effect against S.zeamais improved but not for R.dominica .
