摘要
粗刻点木蠹象和云南木蠹象的雌雄成虫在外部形态上相似度很高,难以区分。文章介绍了2种区分方法。一是在解剖镜下通过观察象虫腹部背板末节上的特征准确区分活体雌雄成虫;二是通过肉眼观察象虫腹部第1节中间部位的特征快速区分活体雌雄成虫,可作为1种简便的野外区分方法。
The external morphology of both sexes of Pissodes punctatus and P. yunnanensis adults are very similar and it is difficult to distinguish them. Two methods for sexing live adults of the two weevils are described. One is identifying terminal tergite of the abdomen with a dissecting microscope. The other is identifying middle shape in the first segment of abdomen with naked eyes, which is a convenient sexing method in the field.
