Identification of Pratylenchus and Hemicriconemoides parasites on garden trees in Nanjing.
A survey on 40 species of rhizosphere parasitic nematode species on garden trees was conducted in Qixia, Jiangning and Pukou districts of Nanjing from October 2009 to July 2010. Two nematode species of Pratylenchus (P. coffeae and P. vulnus) and one nematode species of Hemicriconemoides (H. strictathecatus), were observed and identified in rhizosphere soil of garden trees. H. strictathecatus is a new recorded species in Jiangsu Province. Among the 40 species of host plants, Euonymus alatus and Aesculus chinensis are new host plants of P. coffeae, Cotoneaster horizontalis and Taxus chinensis var. mairei are new host plants of P. vulnus, and Sophora japonica var. pendula is a new host plant of H. strictathecatus.
