摘要
调查了南宁市公园、道路(绿地)2种生境内乔木、灌木和草坪植物3种植被类型的红火蚁活蚁巢密度、发生程度和危害占比,及129种园林植物红火蚁的筑巢率。结果表明:红火蚁发生危害程度为公园生境大于道路(绿地)生境;草坪大于乔木大于灌木。乔木根部有红火蚁筑巢的种类占调查总种类数的44.73%,筑巢率最高的为幌伞枫Heteropanax fragrans(Roxb.)Seem.,达29.17%;灌木根部有红火蚁筑巢的种类占调查总种类数的35.85%,筑巢率最高的为苏铁Cycas revoluta Thunb.,为7.14%。
The active nest density, occurence degree, hazard ratio and the nesting rate of the red imported fire ants on 129 kinds of garden plant were investigated in 3 plant types of arbors,shrubs and lawns in 2 different habitats of park and road in Nanning city. The results showed that the occurence degree in park habitat was greater than that in road, and the degree on lawns was greater than that on arbors and shrubs. The arbors were nested by red imported fire ants accounted for 44. 73 %. Heteropanax fragrans （ Roxb. ） Seem. had the highest nesting rate accounted for 29. 17%. The shrubs were nested by red imported fire ants accounted for 35.85%. Cycas revoluta Thunb. had the highest nesting rate accounted for 7.14%.
