摘要
盾负泥虫Ｌｅｍａｓｃｕｔｅｌｌａｒｉｓ（Ｋｒａａｔｚ．）１年发生１代，以成虫滞育。用与鸭忠跖草ＣｏｍｍｅｌｉｎａｃｏｍｍｕｎｉｓＬ．同科及近缘科、属的植物对其食性进行测定，结果是食性单一，只取食鸭跖草。盾负泥虫的发生期与鸭跖草的苗期同步，幼虫的喜食与鸭路草的多分枝特性相吻合。取食营养位与粘液细胞在鸭跖草植株上的分布及细胞的含糖量关系密切。
Lema scutellaris has one generation per year and overwinters as adult'iiis insect shows a monophagous habit feeding only on Commellina communis, but not other plant species. As shown in our feeding tests, it refuses either the same or the closely-related plant families or genera. The occurrence of the insect issynchronic with the seedling stage of Commellina communis. Feeding of the larvae is coinciding with the richly branching feature of the plant. The nutritional location where the insect feeds on is highly correlated with the distribution of the muscous cells of the plant and the cells' sugar contents.
