Abstract

Abstract. There was a significant negative relationship between the density of Umbonia crassicornis (Amyot & Serville, 1843) aggregations and the average length of the newest growth on its host plant, Lysiloma latisiliquum Benth. (Fabaceae). There was also a significant negative relationship between aggregation size and the dry mass of the teneral adults of both sexes. Teneral female U. crassicornis were significantly longer and had a significantly greater dry mass than their male siblings. I suggest that feeding by treehopper nymphs reduces the nutrient pool of the host plant, resulting in reduced plant and treehopper growth.

粗糙伞形（Amyot&Serville，1843）（半翅目：膜翅目）若虫聚集的大小和密度影响寄主植物和树梢的生长

摘要粗糙伞形花序（Amyot&Serville，1843）的聚集密度与其寄主植物latisiliquum Benth上最新生长的平均长度之间存在显著的负相关。（豆科）。聚集大小与两性teneral成虫的干物质之间也存在显著的负相关关系。与雄性兄弟姐妹相比，特内拉尔雌性粗毛灰蝶明显更长，干重也明显更大。我认为，树梢若虫的喂养会减少寄主植物的营养库，导致植物和树梢的生长减少。

期刊介绍： The Pan-Pacific Entomologist (ISSN 0031-0603) is published quarterly (January, April, July and October) by the Pacific Coast Entomological Society, in cooperation with the California Academy of Sciences. The journal serves as a refereed publication outlet and accepts manuscripts on all aspects of the biosystematics of insects and closely related arthropods, especially articles dealing with their taxonomy, biology, behavior, ecology, life history, biogeography and distribution. Membership in the Pacific Coast Entomological Society includes subscription to The Pan-Pacific Entomologist, and Society Proceedings typically appear in the October issue of each volume.
