| 摘要: |
| 为合理保护和利用天敌及科学地选取抽样方法,开展合肥地区"518"油桃园山楂叶螨和李肖叶甲与其天敌之间空间关系研究,运用地学统计学方法求得天敌和害虫各自半变异函数的变程,用灰色关联度分析方法分析害虫与天敌变程的关联度,关联度值越大的天敌在空间上对害虫的跟随关系越密切。分析了山楂叶螨和李肖叶甲种群数量在全年最多时段5月23日—7月17日的油桃园中8种主要天敌对两种害虫空间跟随关系的密切程度。结果表明,与山楂叶螨空间上跟随关系密切的前3位天敌依次是异色瓢虫、草间小黑蛛和八点球腹蛛;与李肖叶甲空间上跟随关系密切的前3位天敌依次是草间小黑蛛、龟纹瓢虫和八点球腹蛛。用生态位分析法分析油桃树冠不同方位上与山楂叶螨空间上跟随关系密切的前3位天敌依次是草间小黑蛛、异色瓢虫和八点球腹蛛;与李肖叶甲空间上跟随关系密切的前3位天敌依次是草间小黑蛛、异色瓢虫和八点球腹蛛。 |

| Abstract: |
| To protect and utiliz enemies legitimately and choos sampling method scientifically,we conducted research on the spatial relationships of Tetranychus viennensis and Cleoporus variabili with their enemies in "518" nectarine orchard.The range of spatial dependengce (RSDs) of pests and enemies were calculated by the geostatistic methods and the relational grades of RSDs were analyzed by grey relational analysis.The higher the relational grade was,the closer the spatial relationships of pests and enemies were.This study analyzed the spatial relationships of pests and enemies in orchard garden from May 23 to July 17,when the occurring quantities of Tetranychus viennensis and Cleoporus variabili were largest throughout the year.The results showed the top three natural enemies which had close space following relationship with T.viennensis were Harmonia axyridis,Erigonidium graminicola and Theridion octomaculatum and the top three natural enemies which had close space following relationship with C.variabili were E.graminicola,Propylaea japonica and T.octomaculatum.Moreover,Analysis with the method of ecological niche analysis of nectarine canopy in different azimuth showed the top three natural enemies which had close space following relationship with T.viennensis were E.graminicola,H.axyridis and T.octomaculatum and the top three natural enemies which had close space following relationship with C.variabili were E.graminicola,H.axyridis and T.octomaculatum. |
