中文摘要：森林冠层是森林昆虫栖息、取食、避敌的重要生境，其中生活着十分丰富的昆虫物种。但由于乔木树体高大，冠层难于接近，在很大程度上限制了冠层昆虫多样性的研究。冠层昆虫类群结构的划分和冠层昆虫取样技术也是冠层昆虫多样性研究的重要基础。文章综述当前冠层接近和冠层昆虫抽样技术的最新进展，并评述冠层昆虫类群结构划分的方法。
英文摘要：Forest canopy provided an important habitat for many forest insects. However, difficultes for forest access to high forest canopy,to a great extent, restricted the studies on its insect diversity in forest canopy. The guild structure of insects is also a key aspect of insect diversity in forest canopy, as well as the division of insect guilds of forest canopy which are the very basis for sampling and data analyses. The recent canopy access and insect sampling techniques were summarized and the methods of guild division were discussed.
