| 摘 要： | 通过对5种植物提取液的杀虫活性进行初步筛选,结果表明:乌桕叶提取液对小菜蛾2龄幼虫有较强的拒食作用,对供饲叶碟24 h和48 h后的拒食率分别为69.14%和86.15%;其次为蓖麻枝提取液,24 h和48 h后的拒食率分别为56.08%和82.00%。乌桕叶、蓖麻枝和石楠叶提取液对小菜蛾幼虫有非常强的毒杀作用,6 d后校正死亡率分别为82.68%、81.10%和80.32%。 |

| Abstract: | The insecticidal activities of five types of extracts from four plant species against the 2nd instar larvae of Plutella xylostella （ L. ） were tested in the current investigation. The results showed that the extracts of S. sebiferum had strong bioactivities. The antifeeding rate of the extract from its leaf was up to 69.14% in 24 h and 86.15% in 48 h, while that of the extract from its R. communis branch reached to 56.08% in 24h and 82.00% in 48 h. All of the three extracts, which were extracted from the seeds of S. sebiferum, the whole plant of R. communis or the leaves of P. serrulata, demonstrated a strong poison effect. Tested with these extracts, the corrected mortality of the 2nd instar larvae of PluteUa xylostella （ L. ） were 82.68% , 81.10% and 80.32% , respectively, after 6 d. |
