| 摘 要： | 目的 研究宁夏不同区域欧李Cerasus humilis园昆虫群落结构及多样性特征,为制定有效的害虫防治策略奠定基础。 方法 2019年5?9月采用诱捕器诱集法对宁夏3个不同区域欧李园昆虫群落进行调查。 结果 共获得标本4 743头,隶属于10目46科101种。梨小食心虫Grapholitha molesta、东方绢金龟Serica orientalis、小长蝽Nysius ericae、牧草盲蝽Lygus pratensis、双斑萤叶甲Monolepta hieroglyphica、红翅伪叶甲Lagria rufipennis、多异瓢虫Hippodamia variegata、丽草蛉Chrysopa formosa、艾箭蚁Cataglyphis aenescens和黑点食蚜盲蝽Deraeocoris punctulatus为优势种。宁夏不同区域欧李园昆虫群落多样性指数、均匀度指数及丰富度指数由高到低依次为候磨欧李园、玉泉营欧李园、施记圈子欧李园;集中性概率指数由高到低依次为施记圈子欧李园、玉泉营欧李园、候磨欧李园。相似性分析显示:玉泉营欧李园与施记圈子欧李园在8月的昆虫群落结构中等相似(0.60)。害虫与天敌的相关性分析显示:梨小食心虫与多异瓢虫呈显著正相关(P＜0.05);小长蝽与多异瓢虫呈极显著正相关(P＜0.01);红翅伪叶甲与艾箭蚁呈显著正相关(P＜0.05);双斑萤叶甲与丽草蛉呈极显著正相关(P＜0.01)。 结论 相对于玉泉营欧李园和施记圈子欧李园,候磨欧李园的昆虫群落稳定性最高。图2表5参25

| Abstract: | Objective This study aims to clarify the structure and diversity characteristics of insect community of Cerasus humilis orchards in different regions of Ningxia, so as to develop effective pest control strategies. Method The insect community of C. humilis in three different regions of Ningxia was investigated using trap trapping method from May to September in 2019. Result A total of 4743 insect specimens belonging to 10 orders, 46 families and 101 species were obtained. The dominant species were Grapholitha molesta, Serica orientalis, Nysius ericae, Lygus pratensis, Monolepta hieroglyphica, Lagria rufipennis, Hippodamia variegate, Chrysopa formosa, Cataglyphis aenescens and Deraeocoris punctulatus. The descending order of diversity index, evenness index and richness index of insect community of C. humilis orchards was Houmo, Yuquanying, and Shijijuanzi. The concentration probability index from high to low was Shijijuanzi, Yuquanying and Houmo. Similarity analysis showed that the insect community structure in Yuquanying and Shijijuanzi C. humilis orchards was moderately similar in August(0.60). The correlation analysis between pests and natural enemies showed that there was a significant positive correlation between G. molesta and H. variegata (P＜0.05). There existed a very significant positive correlation between N. ericae and H. variegata (P＜0.01), a positive correlation between L. rufipennis and C. aenescens (P＜0.05), and a significant positive correlation between M. hieroglyphica and C. formosa (P＜0.01). Conclusion Compared with orchards in Yuquanying and Shijijuanzi, the C. humilis orchard in Houmo has highest stability of insect community. [Ch, 2 fig. 5 tab. 25 ref.] |
