Aphelenchoides besseyi were activated from their dormant state by soaking infested rice seeds in water at 28 deg C for 12 to 15 hours. The nematodes first feed on the tender primordium of the sprouting seeds but later migrate to the leaf as it unfurls. Symptoms of white-tip disease appear on leaves 16 days after germination.
