摘　　要：用不同日龄的薇甘菊叶片饲养安婀珍蝶5龄幼虫,测定不同营养条件对安婀珍蝶幼虫营养效应的影响。结果表明,取食不同日龄叶片的安婀珍蝶幼虫,其多种食物利用指标存在差异。随着叶片日龄的增加,相对取食量和近似消化率有明显增大。10日龄叶片饲养的试虫,其食物利用率和食物转化率明显高于其他日龄的幼叶和老叶饲养的试虫。The effect of Mikania micrantha of different leaf age on nutritional utilization of the 5th instar larvae of Actinote anteas were investigated. The results showed that the change of leaf age had significant effects on nutritional utilization of Actinote anteas. The relative consumption rate (RCR) and the approximate digestibility (AD) increased with the leaf age. The conversion efficiency of digested food (CEDF) and ingested food (CEIF) were the highest at a leaf age of the 10th day.
