Serological relationships of the eggs and larvae of Meloidogyne incognita, M. javanica, and M. arenaria were studied. Based on agar-gel double-diffusion tests and immunoelectrophoresis, all three species are closely related serologically, however, M. incognita and M. javanica each possess two to three unique serologically active components not shared by the other two species.
