Avalia？？o in vitro do fungo predador de nematoides Duddingtonia flagrans sobre larvas infectantes de ciatostomíneos de equinos (Nematoda: Cyathostominae)

the predatory capacity of one isolate of nematode-trapping fungus duddingtonia flagrans (ac001) on infective larvae of cyathostomes was evaluated in laboratorial conditions in medium water-agar 2% (wa 2%). there was significant reduction (p < 0. 01) of 93.64% in the average of infective larvae of cyathostomes recovered of medium wa 2% at seven day. these results show that the isolated ac001 could be used in the biological control of cyathostomes of horses.
