北京地区六种叶甲幼虫形态比较研究

通过检索表把北京地区常见的6种叶甲：榆绿毛萤叶甲、褐背小萤叶甲、榆黄萤叶甲、柳圆叶甲、菜无缘萤叶甲、十星瓢萤叶甲的幼虫区分开来。然而利用幼虫侧面图、头部正面图、足的侧面图和幼虫背面图等形态比较，进一步深入体现出它们之间的异同。为农林植保工作者提供参考。

A study on morphology of six common chrysomelids at the latval stage in Beijing area

Key to larval stage of six crmmon chrysomelids in Beijing are: Pyrrhalta aenesens Fairmare,Galerucella grisescens (Joannis ), Pyrrhalta maculicollis Motschulsky, Plagiodera versicolora Laichart, Colaphellus bowringi Baly and Oides decempunctatus Billberg. Illustrations on the sinistral aspect of larva, cephalic aspect of head, lateral view of leg and dorsal. ventral views of the thoracic and first, second abdominal segments on each species are also given, in order to make a clear comparison on its morphological charaters.
