HOST STATUS OF 32 PLANT-SPECIES TO MELOIDOGYNE-KONAENSIS

A host suitability study of 32 plant species to Meloidogyne konaensis included 54 vegetable cultivars, 12 field crop cultivars, one Gardenia sp., and two weed species. nest suitability was classified according to a M. konaensis reproductive factor: final population density (Pf) ( eggs + J2) / initial population density (Pi) (eggs). The number of egg s per gram dry root, and a galling index was also included. Reproducti ve factor ranges and percentages of plants in the ranges were as follo ws: Pf/Pi > 5.0, 56.5%; 5.0 greater than or equal to Pf/Pi > 1.0, 24.6 %; 1.0 greater than or equal to Pf/Pi > 0, 15.9%; and Pf/Pi = 0, 3%. P eanut and 'Decicco' broccoli were nonhosts. Few or no galls were obser ved on pepper, corn, ginger, waterchestnut, 'Michihili' chinese and 'M arion' market cabbage, although the reproductive factor of M. konaensi s was above 5 on these plants.
