摘　　要：柳膜肩网蝽是为害柳树、杨树等树木叶片的一种刺吸式害虫。为预防该虫大面积暴发时对常见蔬菜发生转寄主为害,于2016—2017年尝试用5种天然食料柳树叶、番薯叶、结球甘蓝、芹菜和大白菜对山西省晋中市太谷县内柳树上柳膜肩网蝽进行了室内饲养,同时对4种天然食料进行营养成分测定。结果表明,芹菜叶片饲养效果最佳,存活最稳定,平均存活率最高,达到了93.33%,番薯叶的平均存活率最低,只有78.33%。通过对存活率的差异显著性分析及与5种叶片营养成分的对比发现,水分的变化趋势与存活率一致,灰分与存活率相反。推测柳膜肩网蝽选择新寄主的主要标准是寄主植物水分的含量。Hegesidemus habrus Drake is a kind of thorn sucking pest that endangers the leaves of willow and poplar trees. To prevent damage to common vegetables when the insect breaks out in large areas, the paper tried to select five kinds of vegetables（willow leaves, sweet potato leaves, cabbage, celery and Chinese cabbage）for indoor rearing Hegesidemus habrus Drake in 2016-2017 in Taigu county, Jinzhong city, Shanxi province. At the same time, the nutritional components of 4 different natural foods were determined. The results showed that breeding effect of celery leaves was the best and the average survival rate was the highest, reached 93.33%. The average survival rate of sweet potato leaves was the lowest, was only 78.33%. Through a significant difference in survival rate and comparison with nutrient components, it was found that the trend of water change was consistent with survival rate, and ash was opposite to survival rate. It is speculated that the main criterion for selecting new hosts is water content.
