| 摘 要： | 濒危植物四合木(Tetraena mongolica)为我国特有的蒺藜科单种属落叶小灌木.对四合木林地昆虫群落进行了调查,共得昆虫标本11363号,263种.隶属于67个科(或总科)11个目.同翅目的个体数量和优势度指数最高；膜翅目的物种丰富度和多样性指数最大；双翅目的均匀度最大.数量优势类群(＞10％)为木虱和叶蝉类,常见类群(1％～10％)是象甲、小蜂、粒脉蜡蝉、拟步甲、蚂蚁、蝽科、皮蝽、盲蝽、斑翅蝗科昆虫.营养结构中植食性类群在种类和数量上占绝对优势,其中的吸食类昆虫优势度最大；天敌昆虫以寄生性类群为主,多样性最高；捕食性和中性昆虫的种类和数量相对较少,但捕食者的均匀度最高.灌木层与草本层相比,灌木层昆虫群落的物种丰富度和个体数量明显占优；优势种的优势度大.而草本层昆虫群落的多样性和均匀度高.2层整体的相似性低.膜翅目的共有种最多.
