USE OF ESTERASE AND PROTEIN-PATTERNS TO DIFFERENTIATE 2 NEW SPECIES OF APHELENCHOIDES ON RICE FROM OTHER SPECIES OF APHELENCHOIDES AND FROMDITYLENCHUS-ANGUSTUS AND D-MYCELIOPHAGUS

Three populations of Aphelenchoides besseyi, one population of A. bica udatus, A. arachidis, A. fragariae, A. hamatus, two undescribed specie s of Aphelenchoides from rice and Ditylenchus angustus and D. myceliop hagus were analyzed by native and SDS-PAGE electrophoresis. The highly reproducible banding patterns of all species differed in number, conc entration and relative mobility. Certain enzyme bands were common betw een the species whereas other bands were specific. There were no detec table differences in the protein and esterase banding patterns of nema todes extracted from cultures of Botrytis cinerea or Rhizoctonia cerea lis. The stability and taxonomic usefulness of the alpha, beta esteras e banding patterns are discussed.
