Author: M. ASLAM Publishing Date: 2010 E-ISSN: 0255-7576 Volume: 28 Issue: 1 ABSTRACT: The effect of different relative humidities and osmotic stress on the survival of Meloidogyne chitwoodi and M.fallax second-stage juveniles(J2) was examined. Experiments were carried out at 250C. J2 of M. chitwoodi and M.fallax could not survive desiccation when expoxed to low relative humidities (RH) of 33%, 59% and
