The survival of desiccation by O. phyllobia infective larvae was examined at controlled relative humidites. When nematodes were transferred from water to air at 10% relative humidity (rh), 80% died within 30 min. When nematodes were transferred from water to air with rh at 70% or greater for approximately 15 min. prior to being transferred to 10% rh., more than 90% of them survived desiccation. This phenomenon, referred to as preconditioning, occurred at much faster rates (2 to 30 min) than has been observed for other nematode species (24 h). Differences in preconditioning rates may be due to technique-dependent variations in boundary layer resistance around nematodes during desiccation.
