摘　　要：为了探究浙江主要桃产区(嘉兴、富阳、奉化)桃园昆虫群落结构和多样性,本实验使用马来氏网法、灯诱法、黄盘法等采集各桃园昆虫,并鉴定到科、属、种,将其分为天敌类昆虫、害虫类昆虫,进而筛选出优势种等。结果显示,共采集昆虫标本23247号,其中嘉兴桃园13826号,富阳桃园5577号,奉化桃园3844号;鞘翅目、鳞翅目、半翅目、双翅目等为优势类群。不同桃园昆虫群落多样性(Shannon-Wiener)指数和均匀度指数为富阳>奉化>嘉兴,物种丰富度为富阳>奉化>嘉兴,优势集中性指数为富阳<奉化<嘉兴。稳定性分析的结果表明富阳桃园昆虫群落中,天敌类昆虫对害虫类昆虫能起到较好的调控,拥有较强的适应和抵抗外界干扰的能力。综合以上各项昆虫群落分析的结果,表明富阳桃园的昆虫群落稳定性最高。To reveal the structure and diversity of insect community in three main peach production areas（ Jianxing peach orchard,Fuyang peach orchard,Fenghua peach orchard） in Zhejiang,insects community diversity was investigated by Malay net trapping,lamp trapping and yellow-pan trapps in this present study and identified to families,genus,even to species. Also,they were divided into natural enemies,neutral insects and injurious insects,and then select the dominant species. The results showed that 23247 insects were collected,13826 insects from Jiaxing peach orchard,5577 insects from Fuyang peach orchard,3844 insects from Fenghua peach orchard. Among them,insects in Coleoptera,Lepidoptera,Hemiptera andDiptera were the dominant groups. According to the value of the diversity index（ H＇） and evenness index（ J）,the order was Fuyang〉Fenghua〉 Jiaxing. The richness index（ S） showed the same sequence,however,the dominant concentration（ C） has a different order which was Fuyang〈 Fenghua〈 Jiaxing.Stability analysis results showed that the Fuyang peach orchard＇s internal structure of food web was more complex,that means natural enemies could control the injurious insects well, had strong ability of adaptation and resistance to interference. Based on the above analysis results of insect community,it showed that the insect community stability was highest in Fuyang peach orchard.
