石榴园5种主要食叶类害虫与其捕食性天敌之间的关系

Relationship between five major phytophaga pests and their natural predatory enemies in pomegranate field

  • 摘要: 为统筹利用自然天敌和通过化学措施全年综合防治石榴园害虫, 对石榴园害虫及其天敌进行了系统调查, 明确了江淮丘陵区石榴园主要食叶类害虫为棉蚜、小绿叶蝉、黄刺蛾、扁刺蛾和小袋蛾。采用灰色关联度分析法、生态位分析法和空间格局聚集强度指数分析法分析了主要害虫与其捕食性天敌在数、时、空方面的关系, 综合排序得出: 棉蚜的主要捕食性天敌是异色瓢虫、中华草蛉和八斑球腹蛛, 小绿叶蝉的主要捕食性天敌是粽管巢蛛、三突花蟹蛛和草间小黑蛛, 黄刺蛾的主要捕食性天敌是粽管巢蛛、锥腹肖蛸和八斑球腹蛛, 扁刺蛾的主要捕食性天敌是锥腹肖蛸、八斑球腹蛛和粽管巢蛛, 小袋蛾的主要捕食性天敌是三突花蟹蛛、粽管巢蛛和异色瓢虫。棉蚜种群的聚集均数l值大于2, 其聚集是本身原因引起的; 而小绿叶蝉、黄刺蛾、扁刺蛾和小袋蛾及其捕食性天敌的l值小于2, 其聚集是环境中某些因子引起的。

     

    Abstract: The purpose of this study was to provide a scientific basis for the comprehensive control of pests in pomegranate fields using natural predatory enemies and chemical measures. Through the systematic investigation of the pests and natural predatory enemies in pomegranate fields, the paper identifies Aphis gossypii, Cnidocampa flavescens, Empoasca flavescens, Thosea sinensis and Cryptothelea minuscula as the major phytophaga pests in the hilly pomegranate fields of Jianghuai Area. The relationship in number, time and space between the major pests and their natural predatory enemies was studied through correlation analysis, ecological niche analysis and spatial pattern aggregation intensity index analysis. The comprehensive results show the order of the main natural predatory enemies of the major phytophaga pests as follows — A. gossypii: Harmonia axyridis, Chrysopa sinica and Theridion octomaculatum; C. flavescens: Clubiona japonicola, Misumenops tricuspidatus and Erigonidium graminicolum; E. flavescens: C. japonicola, Tetragnatha maxillosa and T. octomaculatum; T. sinensis: T. maxillosa, T. octomaculatum and C. japonicola; C. minu-scula: M. tricuspidatus, C. japonicola and H. axyridis. The cumulative average (l) of A. gossypii community excesses 2, this is because of the aggregation nature of the insect. On the other hand, the cumulative averages of communities of C. flavescens, E. flavescens, T. sinensis, C. minuscule, and natural predatory enemies are less than 2. This is mainly due to uncertain environmental factors.
