Populations of Xiphinema americanum and X. rivesi were collected from apple orchards in eastern and western New York, USA, and tested in the laboratory for their ability to transmit tomato ringspot virus (TmRSV) to cucumber and dandelion [Taraxacum officinale]. Populations varied in the frequency with which they transmitted TmRSV, but this variation did not correspond to the variation in disease prevalence in the orchard. The lower prevalence of TmRSV-incited disease in apple trees in western New York cannot be attributed to the inability of the local Xiphinema spp. to transmit TmRSV.
