摘要: 采用灰色系统分析方法,分析了对主要害虫棉蚜及其天敌日捕食总量之间关联度.结果表明,棉蚜群落中与其关联度较高的天敌种类依次为肖蛸蛛(0.8607)、中华草蛉(0.8058)、八斑球腹蛛(0.7989)、异色瓢虫(0.7881)和大草蛉(0.7758),与理想天敌日捕食总量间关联度较高的天敌种类为草间小黑蛛(0.8975)、智利小绥螨(0.8132)、龟纹瓢虫(0.7806)和大草蛉(0.7669);与天敌数量间关联度较高的天敌依次为草间小黑蛛(0.8482)、中华草蛉(0.7533)、肖蛸蛛(0.7532)、八斑球腹蛛(0.7411)和大草蛉(0.7116),与理想天敌数量间关联度较高的为草间小黑蛛(0.8461)、智利小绥螨(0.7325)、龟纹瓢虫(0.6983)、大草蛉(0.6815)和中华草蛉(0.6757).棉蚜垂直生态位和水平生态位的重迭值均>0.9567的天敌有草间小黑蛛、大草蛉和肖蛸蛛;时间生态位重迭值>0.4020的天敌有草间小黑蛛、大草蛉和肖蛸蛛,表明草间小黑蛛、大草蛉、肖蛸蛛等为棉蚜主要天敌优势种.

Abstract: In this paper,the relevancy of Aphis gossypii with its natural enemies was studied by using grey systematic analysis.The results showed that the major natural enemies of Aphis gossypii were Tetragnathidae (0.8607),Therdion octomaculatum (0.8058),Therdiono ctomaculatum (0.7989),Haramonia aiyridis (0.7881) and Chrysopa sepetempunctata (0.7758).As for the daily total predation,the natural enemies which highly associated with the ideal dominant natural enemies were Erigonidium graminicola (0.8975),Tromobidiidae (0.8132),Propylacea japonica (0.7806) and Chrysopa sepetempunctata (0.7669); while for the quantity,Erigonidium graminicola (0.8482),Chrysopa sinica (0.7533),Tetragnathidae (0.7532),Therdiono ctomaculatum (0.7411) and Chrysopa sepetempunctata (0.7716) were the major natural enemies.According to the relational grade of the individuals between various natural enemies and ideal dominant natural enemies,the major natural enemies were Erigonidium graminicola (0.8461),Tromobidiidae (0.7325),Propylacea japonica (0.6983),Chrysopa sepetempunctata (0.6815) and Chrysopa sinica (0.6757).The species having >0.9567 horizontal and vertical niche overlaps with Aphis gossyppii were Erigonidium graminicola,Chrysopa sepetempunctata and Tetragnathidae,while the temporal niche overlaps between Erigonidium graminicola,Chrysopa sepetempunctata,tetragnathidae and Aphis gossyppii were >0.4020.It could be concluded that the main natural enemies of Aphis gossyppii were Erigonidium graminicola,Chrysopa sepetempunctata and Tetragnathidae.
