摘要

在台湾的二级寄主金龟子上,金龟子蚜虫与不育的士兵形成羊毛群落。然而,到目前为止,还没有发现C.monstrivica的胆囊或主要宿主代。我们通过将其卵附着在树上,成功地在泽尔科娃锯齿树上诱导了该物种的胆囊,并在另一棵泽尔科瓦锯齿树上发现了一些自然形成的胆囊。通过检查它们的线粒体DNA序列,确认了蚜虫的身份。galls中的一龄和二龄若虫对人工引入的蛾幼虫表现出攻击行为。扫描电子显微镜观察显示,胆囊内表面密被微小的毛状体覆盖。这表明了内表面的拒水性,并表明Monstrivica的年轻若虫会在胆囊外处理蜜露球,如同类Colophina中所知 铁线莲。

Defensive nymphs and water-repellency in previously unknown galls of the social aphid Colophina monstrifica (Hemiptera: Aphididae: Eriosomatinae)

The aphid Colophina monstrifica forms woolly colonies with sterile soldiers on the secondary host Clematis uncinata in Taiwan. However, the gall or primary-host generation of C. monstrifica has not been found to date. We successfully induced galls of the species on Zelkova serrata by attaching its eggs to the trees, and also found a few naturally formed galls on another Z. serrata tree. The identity of the aphids was confirmed by examining their mitochondrial DNA sequences. First and second instar nymphs in the galls exhibited attacking behavior toward artificially introduced moth larvae. Observations with a scanning electron microscope revealed that the gall inner surface was densely covered with minute trichomes. This indicates the water repellency of the inner surface, and suggests that young nymphs of C. monstrifica dispose of honeydew globules outside the gall, as known in the congener Colophina clematis.

期刊介绍: Entomological Science is the official English language journal of the Entomological Society of Japan. The Journal publishes original research papers and reviews from any entomological discipline or from directly allied field in ecology, behavioral biology, physiology, biochemistry, development, genetics, systematics, morphology, evolution and general entomology. Papers of applied entomology will be considered for publication if they significantly advance in the field of entomological science in the opinion of the Editors and Editorial Board.
