摘　　要：油蒿是我国北方农牧交错带的重要固沙植物,近年来受到油蒿钻蛀性害虫的危害,导致大面积死亡。2006年5月至2007年9月在宁夏盐池县对油蒿不同演替阶段的油蒿钻蛀性害虫混合种群的组成和数量变化及环境因子进行系统的调查,结果表明:危害油蒿的钻蛀性害虫分别是沙蒿大粒象、沙蒿木蠹蛾、沙蒿圆吉丁虫和一种蛀茎蛾(鳞翅目:卷蛾科);在油蒿不同演替阶段,上述4种油蒿钻蛀性害虫均有危害,且每个阶段的优势种各不相同;线性逐步回归分析表明油蒿钻蛀性害虫混合种群受油蒿林的演替阶段及油蒿群落的微环境影响较大。Artemisia ordosica is an important shrub widely distributed in northern China for combating desertification. Recently large areas of A. ordosica were damaged by several species of woodborers. However, few studies have focused on these woodborers of A. ordosica. To better understand the relationships between occurrence of these woodborers and environmental factors, a systematic survey was conducted at 3 different successional stages of A. ordosica in Yanchi, Ningxia Hui Autonomous region, China from May 2006 to September 2007. The results showed that the woodborers attacking A. ordosica included： Holcocerus artemisiae, Adosopius sp., Sphenoptera sp. and a species of Tortricidae. All these 4 woodborer species attacked A. ordosica at 3 different successional stages of A. ordosica, and the dominant species were alternative at each successional stage. Linear stepwise regression analysis was used to establish relations between environment factors and population dynamics of these woodborer species.
