江淮丘陵和黄河故道不同施肥处理葡萄园葡萄十星叶甲Oides decempunctata与其天敌的关系

在运用葡萄丰产栽培措施的同时,为合理保护和利用自然天敌进行葡萄十星叶甲的综合防治,对安徽省萧县和肥东县喷施钕肥、镧肥、醋肥和清水的葡萄园葡萄十星叶甲及其主要天敌进行系统调查,并用灰色系统分析法和生态位分析法对两者之间在数量、时间和空间格局等方面的关系进行分析。经综合排序,萧县十星叶甲主要天敌喷水处理区为龟纹瓢虫、草间小黑蛛和拟环纹狼蛛,喷醋处理区为拟环纹狼蛛、龟纹瓢虫和异色瓢虫,喷钕处理区为草间小黑蛛、异色瓢虫和龟纹瓢虫,喷镧处理区为龟纹瓢虫、异色瓢虫和草间小黑蛛。肥东县十星叶甲主要天敌喷水处理区为草间小黑蛛、八斑球腹蛛和拟环纹狼蛛,喷醋处理区为拟环纹狼蛛、草间小黑蛛和龟纹瓢虫,喷钕处理区为草间小黑蛛、拟环纹狼蛛和八斑球腹蛛,喷镧处理区为八斑球腹蛛、草间小黑蛛和拟环纹狼蛛。萧县和肥东县两地间各处理的十星叶甲主要天敌的种类和位次差异明显。喷水区两地相同的两种主要天敌是草间小黑蛛和拟环纹狼蛛,喷醋区两地相同的两种主要天敌是拟环纹狼蛛和龟纹瓢虫,喷钕区和喷镧区两地相同的主要天敌都是草间小黑蛛。

Relationship between Oides decempunctata and its natural enemies under different fertilization treatments in grapery in Jianghuai hilly region and ancient course of the Yellow River

A systematic investigation of O. decempunctata and its natural enemies was conducted in grapery under four fertilization treatments (water, vinegar, neodymium and lanthanum spray) in order to protect and use natural enemies in integrated pest management and high-yield cultivation of graperies in Xiaoxian County and Feidong County, Anhui Province. Grey systematic and ecological niche analyses were used to establish the number and spatio-temporal distribution correlations between O. decempunctata and its natural enemies. The results of synthetic ranking are that, for Xiaoxian grapery, the main natural enemies of O. decempunctata are Propylaea japonica, Erigonidium graminicolum and Lycosa pseudoannulata under water spray treatment; L. pseudoannulata, P. japonica and Harmonia axyridis under vinegar spray treatment; E. graminicolum, H. axyridis and P. japonica under neodymium spray treatment; and P. japonica, H. axyridis and E. graminicolum under lanthanum spray treatment. For Feidong grapery, the main natural enemies of O. decempunctata are E. graminicolum, Theridion octomaculatum and L. pseudoannulata under water spary treatment; L. pseudoannulata, E. graminicolum and P. japonica under vinegar spray treatment; E. graminicolum, L. pseudoannulata and T. octomaculatum under neodymium treatment; and T. octomaculatum, E. graminicolum and L. pseudoannulata under lanthanum spray treatment. Natural enemies of O. decempunctata distinctly vary with treatment type and location. The most common natural enemies of O. decempunctata in two locations are E. graminicolum and L. pseudoannulata under water spray treatment, L. pseudoannulata and P. japonica under vinegar spray treatment, and E. graminicolum under neodymium and lanthanum spray treatments.
