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。
Artemisia ordosica and A.sphaerocephala are important plants in the western desert steppe of Inner Mongolia. In recent years, the deaths due to pests have been very serious. Harmful of pests in Artemisia annua mulberry borer mulching more harmful species, is one of the main factors leading to the death of Artemisia. According to the field observation from 1983 to 1985, the morphological characteristics, biological characteristics and damage habits of Artemisia lanceolata, Artemisia halodendron, Artemisia annua and Artemisia annua were preliminarily studied.
