| 摘 要： | 对玉米田昆虫群落进行了系统调查,通过从群落生态学的角度进行分析,运用群落的重要指标相对多度、物种丰富度（S）、优势度（d）、多样性指数（H~1）、生态优势度（C）进行分析研究,基本探清了玉米田昆虫群落的组成及其变动情况.经调查得知玉米田昆虫群落由31个种组成,分属于11个目、22个科.昆虫数量由大到小依次为鳞翅目、鞘翅目、半翅目、直翅目、双翅目、同翅目、脉翅目、膜翅目、缨翅目、蜘蛛目、蜱螨目.在整个调查期间都处于优势地位的是玉米蚜Rhopalcsiphum maidis、异色瓢虫Harmonia axyridis和七星瓢虫Coccinellaseptempunctata.根据玉米田昆虫群落的组成与结构、发生发展特点,为农业生产提供指导,便于合理安排农业生产和进行农业害虫防治.

| Abstract: | Based on the com field insect community,the important indexes such as community relative abundance, species richness index,dominance index（S）,dominant（d）,diversity index（H＇） and ecological advantage degree（C） was studied and analyzed.The results showed that corn field insect community consisted of 31 species,belonging to 11 orders, 22 families.Insect community by large quantity order Lepidoptera,Coleoptera,Hemiptera,Orthoptera,Diptera,Homoptera, Neuroptera,Hymenoptera,Thysanoptera.Rhopalosiphum maidis,Harmonia axyridis and Coccinella septempunctata were dominant species during the whole investigation.According to insect community composition and structure in corn field,development characteristics,to provide guidance for agricultural production,reasonable arrangement of agricultural production and agricultural insect pest control. |
