摘　　要：2008-2010年连续3年对广西桉树人工林的昆虫多样性调查，获取的昆虫标本隶属18目82科134种。昆虫群落多样性在桉树造林后1年内下降，2—3年后恢复甚至超过造林前的水平；桉树人工林内不同功能昆虫亚群落的结构比较合理，天敌昆虫种类比较丰富，对植食性昆虫的种群增长发挥重要的自然控制作用。During three consecutive years of spring and summer survey, 18 428 insect specimens were collected, belonging to 18 orders, 82 families and 134 species. After a short time of afforestation, in- sect diversity in eucalypt plantations was decreased. But 2--3 years later, it could be restored or even more than before. In eucalypt plantations, the structure of different functional insects sub-community was reasonable, and species of enemy insects were rich, which played a good role in natural control of plant-eating insect populations.
