Increasing populations of M. enterolobii ? 0, 500, 1,500, 3,000, 5,000, and 7,000 eggs and second-stage juveniles (J2) per plant, ? were evaluated, in a completely randomized design. The pathogen showed a parasitism pattern similar to that of M. incognita, causing a significant decrease in morphological and agronomic traits. The pathogen reproduction factor should be used in the selection of okra genotypes for tolerance to M. enterolobii, in populations above 3,000 eggs or J2.  aRoot-knot nematodes  aAbelmoschus Esculentus  aFator de reprodução  aHospedeiro suscetível  aNematódeo-da-galha  aReproduction facto  aSusceptible host1 aSOARES, R.
