| 摘 要： | 为准确快速地鉴定椰心叶甲和水椰八角铁甲这2种入侵害虫，通过显微镜观测二者全虫态的形态学特征并进行分析，发现椰心叶甲和水椰八角铁甲部分形态学特征差异较大，主要有：前者卵长小于后者，但卵宽大于后者；前者卵呈一字型排列，后者的卵并向排列；前者老熟幼虫体长、蛹长显著大于后者，但蛹宽小于后者；前者成虫前胸背板有6个角，后者有8个。结果表明，利用形态学特征和体长、体宽参数可较好地区分二者。研究有助于相关研究人员快速有效地鉴定这2种重要的入侵害虫，并为研究其在我国的分布和危害情况提供一定帮助。 |

| Abstract： | To accurately identify Brontispa longissima (Gestro) and Octodonta nipae (Maulik), their morphological characteristics were compared through the microscope observation. Results showed that there were significant differences between B. longissima and O. nipae in morphological characteristics. B. longissima had larger egg-width and shorter egg-length, and its eggs were arranged in one line, while O. nipae’s eggs were in a double-line arrangement; B. longissima showed a larger size in body length of mature larvae and pupae, but a shorter pupal width; eight obvious denticulation existed in pronotum of adult for O. nipae, while only six for B. longissima. The present results should facilitate rapid and effective identification, and pave the way for the researches of the occurrence and damage for these two invasive pests. |
