摘　　要：褐背小萤叶甲为寡食性昆虫,嗜食蓼科植物,为蓼科田间杂草的重要天敌。本文首次报道了发生在千屈菜上的褐背小萤叶甲的生物学特性和危害情况,表明褐背小萤叶甲能在千屈菜上取食为害,完成其生活史,是一种千屈菜害虫。Galerucella grisescens, an oligophagous insect, was an important natural enemy of Polygonaceae plants. The biological characteristics of G. grisescens and damages to the purple loosestrife were reported for the first time in this paper. The results showed that G. grisescens, which could complete its life cycle by feeding on the purple loosestrife, is a pest insect of it.
