沙蒿钻蛀性害虫的初步研究

沙蒿(Artemisia ordosica和A.sphaerocephala)是内蒙西部荒漠草原重要植物,近年由于害虫为害,死亡很严重。为害沙蒿的害虫中以钻蛀为害的种类较多且为害轻重,是导致沙蒿死亡的主要因素之一。本文根据1983～1985年的实地观察,对沙蒿大粒象、沙蒿木蠹蛾、沙蒿圆吉丁虫和沙蒿蛀茎蛾的形态特征、生物学特点及为害习性进行了初步研究。

A Preliminay Study on Artemisia Borer

The wormwood, Artemisia ordosoca and A. sphaerocephala, were important plants in desert grassland in the west of Inner Mongolia. A lots of them were died in recent years after seriously damaging by insect pests. The borers were main pests among those insects for their deadly attacking, and they became primary factors causing the death of wormwood. This paper, based on the researches in artemisia land from 1983 to 1985, deals with the morphological and biological characteristics and damaging habits of four borers, artemisia weevil, Ardosomus sp., a cossid, Holcocerus sp., a borer beetle, Sphenoptera sp., and a moth. Their natural enemies and control methods are included in the studies.
