Effect of Three Plant Species on Population Densities of Xiphinema americanum and X. rivesi
AbstractA taxonomic revision of the Xiphinema americanum species complex has necessitated a reexamination of the host range of species in the complex before recommendations can be made with confidence on the likelihood that specific crops will be damaged. Toward this end, populations of X. americanum and X. rivesi collected from apple orchards in eastern and western New York state were evaluated after 3 months in pots planted with cucumber, apple, or dandelion seedlings. Eastern and western New York populations of both nematode species declined on cucumber but increased to similar final densities on apple and dandelion. Key words: apple, cucumber, Cucumis sativus, dandelion, Malus domestica, Taraxacum oficinale, Xiphinema americanum, X. rivesi.
