摘　　要：对幼龄龙眼园昆虫群落进行调查研究.结果表明,幼龄果园昆虫组成主要有10目41科60种昆虫,其中害虫43种,天敌11种,中性昆虫6种.昆虫群落指数有明显的时间变化,害虫在4、8-10月份优势度高;5-9月份,物种丰富度保持在较高水平;4-10月份,多样性和均匀度指数高,优势集中性指数低.在防治时注意保护利用天敌,科学用药,保护果园生物多样性,创造有利于天敌的生境,达到害虫可持续控制的目的.The structure and dynamics of insect community in young longan orchard were investigated. It was shown that insect community was composed of 10 orders, 41 families and 60 species in the young longan orchard, including 43 species of pest, 11 species of natural enemies and 6 species of moderate insects. Insect community indices were fluctuated with time obviously. The dominance index of pest was high from August to October and in April. From May to September, species richness was kept at a high level. During the period from April to October, diversity and evenness were high, and dominant concentration index was low. To obtain the sustainable control, natural enemies and biodiversity protection should be taken into considcration.
