A simplified small apparatus for extracting nematodes was designed and its extraction efficiency was tested using Bursaphelenchus xylophilus in dead Pinus densiflora wood. The extraction efficiency of the simplified apparatus was not significantly different from that of an ordinary 9-cm diameter BAERMANN funnel when the sample amount was appropriate. The simplified apparatus is small (ca. 3cm×3cm×10cm) taking up about 5% of the space required by the 9-cm BAERMANN funnel. It is expected to be useful when extracting nematodes in a small chamber or when treating large numbers of samples at one time.
