伪星翅蝗 Calliptamus coelesyriensis(G.-T.)近年来随着草场生态环境的改变,由次生种逐渐上升为优势种群,在本地区分布较广,是牧草的重要害虫之一。大发生时为害率达100%,使整个草场被毁。为了摸清此蝗的发生规律,及时进行防治,我们从1987年开始,在巩留县提克阿热克乡以南夏尔布穷草场进行了观察研究,现将结果介绍如下。一、分布与寄主伪星翅蝗在新疆天山北部均有分布,内地尚无报道。本地区以巩留、特克斯、察布察尔、伊宁等县发生较重,霍城、尼勒克、新源等县轻些。主要分布在平原和丘陵海拔700～ Calliptamus coelesyriensis (G.-T.) In recent years, with the changes of grassland ecological environment, the secondary species gradually rose to the dominant species and distributed widely in the region. Damage occurred at the time of the big 100%, so that the entire pasture was destroyed. In order to find out the regularity of this locust and promptly carry out prevention and treatment, we started from 1987 and observed and studied on the poor grass field of Che’erbu south of Tikh Akek, Gongliu County. The results are as follows. First, the distribution and host Pteridoptera locusts are distributed in the northern part of Tianshan Mountains in Xinjiang, the Mainland has not yet reported. The districts of Gongliu, Turks, Qabuchar, Yining and other counties were heavier in the region, with Huocheng, Niluok and Xinyuan counties being lighter. Mainly located in the plains and hills 700 ~ above sea level
