[目的]掌握杞柳瘿蚊(Rhbdophaga SP)的形态特征。[方法]2008年3月至2010年7月对安徽省霍邱县沿淮环湖区域杞柳瘿蚊的外部形态特征进行了观察,并对幼虫和蛹分别进行了龄期和历期的划分。[结果]对杞柳瘿蚊各虫态(卵、幼虫、蛹和成虫)的分级特征作出了细致描述。根据幼虫的发育和蜕皮次数,确定幼虫有3龄(1、2、3龄),其形态、大小差异变化较大;蛹为裸蛹,根据其发育可分为前期、初期、中期、后期4个阶段。[结论]为进一步研究杞柳瘿蚊提供了参考。
[Objective] To understand the morphological characteristics of Rhbdophaga sp. [Method] From March 2008 to July 2010, the external morphological characteristics of Qianyihuang mosquito in the Huaihe Lake area of Huaiqiu County, Anhui Province were observed. The larvae and pupae were divided into different periods and periods. [Result] The grading characteristics of all the insect states (eggs, larvae, pupae and adult) of Qianyuanjiao were elaborated. According to the larvae development and molting frequency, the larvae were determined to have the 3rd instar (1, 2, and 3 instars), and the morphological changes of the larvae varied greatly. The pupae were nude pupal. According to their development, the larvae were divided into the early stage, the early stage, the middle stage and the later stage A stage. [Conclusion] This provided a reference for further study on
