摘要
北贝肩网蝽Dulinius conchatus Distant近年来传入许多国家,是一种危险性的入侵害虫,对我国茜草科植物鸡矢藤Paederia scandens造成严重危害。对北贝肩网蝽进行室内饲养,观察发现其卵细长,呈香蕉型,略显米黄色;若虫分为5龄,随着若虫龄期增长,体长、体宽和头宽逐渐增加;成虫头兜呈球状,两个半球型的壳直立于背板上;雄成虫腹部扁平,末端有抱握器,形似牛角状;雌成虫腹部宽大,末端有产卵器。本研究对北贝肩网蝽各龄期形态学数据进行测量,明确了各虫龄虫态的外部形态和为害特征,为该害虫防治提供相关依据。
A destructive invasive pest,Dulinius conchatus Distant has been introduced into many countries in recent years.Which was,causing serious harm to Paederia scandens in China.The indoor feeding and observation of D.conchatus were conducted,,The results showd that its eggs were slender,banana-shaped,slightly beige.The nymphs were divided into 5 instars.The body length,body width and head width gradually increased with the growth of nymphs instar.The adult head pocket were spherical,and two hemispherical shells stand upright on the backplane.The male adult had a flat abdomen and a pair of claspers at the end,shaped like an ox horn.While the female adult had a wide abdomen and an ovipositor at the end.In this paper,morphological data of D.conchatus at each instar stage were measured,and the external morphology and damage characteristics were clarified,so as to provide relevant basis for the control of the pest.
