Observations on the Host Range of Meloidogyne nataliei . C. J. DIAMOND, Former Graduate Research Assistant, Michigan State University, East Lansing 48824. G. W. BIRD, Professor, Department of Entomology, Michigan State University, East Lansing 48824. Plant Dis. 78:1050-1051. Accepted for publication 27 July 1994.

Meloidogyne nataliei is a root parasite of Vitis labruscana cv. Concord. Evaluation of 20, 7, and 9 plant species as potential hosts for this nematode under greenhouse, field, and growth chamber conditions, respectively, indicated that M. nataliei has a narrow host range. Nematode development and reproduction were not observed on 30 of the species. Five new hosts of M. nataliei were identified: three Vitis rootstocks (5BB, St. George, and Gloire), Parthenocissus quinquefolia, and P. tricuspidata.
