Abstract: 

IN ORDER TO IDENTIFY AND DETERMINE SPECIES OF MELOIDOGYNE, OVER 135 SAMPLES PERINEAL PATTERNS OF FEMALE ROOT-KNOT NEMATODES, COLLECTED FROM DIFFERENT PARTS OF PROVINCE , WERE STUDIED. IN THIS INVESTIGATION FOUR SPECIES OF MELOIDOGYNE WERE FOUND. THESE WERE MELOIDOGYNE JAVANICA, M.INCOGNITA, M.HAPLA AND M. ARENARIA WHICH WERE IDENTIFIED BY THEIR PERINEAL PATTERNS AND MORPHOLOGICAL CHARACTERS OF SECOND STAGE JUVENILES (J2).THE BEHAVIOR OF 65 POPULATIONS OF FIRST TWO AND THE LAST SPECIES ON DIFFERENTIAL HOSTS INDICATED THAT TWO RACES OF M. INCOGNITA (NOS TWO AND FOUR) AND ONE RACE OF M.ARENARIA (NO.TWO) WERE PRESENT IN SAMPLED AREAS.
