Other Contributions: A Simple Siphon Method for Separating Nematodes from Excess Water

摘要

A siphon method is used to concentrate nematodes. The water-nematode residuum is poured into the wash bottle and left to settle for 5 or more hr. Rubber tubing of 3-mm inside diam, filled with water to form the siphon, is then slipped over the spout and with a head of 47 cm the excess water is emptied in about 6 min leaving a nematode concentrate of 10 to 45 ml. There were no significant differences in losses (0.5% or less) from single species or mixed species of nematodes.
