中文摘要:

外来入侵害虫菊方翅网蝽Corythucha marmorata Uhler，1878（半翅目：网蝽科）自传入我国后分布范围迅速扩张。本文利用扫描电子显微镜对菊方翅网蝽的外部形态进行了深入研究，重点关注了卵、若虫到成虫在个体发育过程中超微结构的变化。卵表面光滑，卵盖具蜂窝状小室。1~3龄若虫触角3节，4龄若虫至成虫，鞭节分为2节；在触角上发现了5类感器：2类毛形感器（Sensilla Trichodea）和3类锥形感器（Sensilla Basiconica）；在若虫阶段发现了4种类型的体表突起：鳞片状突起、三角形突起、棒状突起和短柄蘑菇状突起，在发育过程中数量增加；1龄若虫体表瘤突简单，与2~5龄不同，后者瘤突结构保持不变，但分枝变多、变长。研究结果有助于入侵害虫菊方翅网蝽的早期识别，并为相关类群的系统发育分析提供更多数据。

英文摘要:

In this study, the external morphology of Corythucha marmorata Uhler, 1878 (Hemiptera∶Tingidae) was examined by scanning electron microscopy, with emphasis on the ontogenetic changes of the integument ultrastructures from eggs, nymphs to adults. The surface of the eggs is smooth, with crests and honeycomb shape cells around operculum. In the nymphs, the antennae of the first to third instars of C. marmorata, consist of only 3 segments, and the flagellum splits into 2 flagellomeres from the fourth instar nymphs to the adult; 5 morphological types of sensilla were identified on the antennae: Sensilla Trichodea 1, Sensilla Trichodea 2, Sensilla Basiconica 1, Sensilla Basiconica 2, Sensilla Basiconica 3; 4 types of projections increased in number during ontogeny: scale-like, triangular, claviform setae, and short-stalked mushroom-shaped projections; the integumentary tubercles of the first instar differed from those of the second to fifth instars, while the structure of the latter remained the same, but became more branched and longer. The results could help in the early identification of the invasive lace bug and provide more data for use in phylogenetic analyses.
