摘　　要：为阐明柚园害虫及天敌的群落结构及多样性,于2021年5月至11月利用马氏网对梅州地区柚园的昆虫群落进行了系统调查.全年共获得昆虫标本4011个,隶属于于11目、67科;主要以鳞翅目(Lepidoptera)、双翅目(Diptera)、膜翅目(Hymenoptera)、鞘翅目(Coleoptera)昆虫为主,其中鳞翅目的夜蛾科(Noctuidae)和膜翅目姬蜂科(Ichneumonidae)分别是科级优势害虫和天敌.结果表明,梅州地区柚园昆虫群落结构的丰富度指数、多样性指数和均匀度指数较高,三者的时序动态呈一致趋势,说明柚园昆虫群落具有较高的稳定性.[Objective]To learn the community structure and diversity of pests and natural enemies in pomelo orchard,[Methods]The insect community in pomelo orchard was systematically investigated by malaise trapping from May to November 2021.[Results]A total of 4011 insect specimens were obtained,belonging to 11 orders and 67 families;The main orders were the Lepidoptera,Diptera,Hymenoptera and Coleoptera,and the main dominant families of pests and natural enemies were Noctuidae(Lepidoptera)and Ichneumonidae(Hymenoptera).[Conclusion]The results of diversity analysis show that diversity,evenness and richness,indices were high consistently,indicating that the insect community in pomelo orchard has high stability.
