Six isolates of nematophagous fungi Monacrosporium thaumasium (isolate NF 34A), Monacrosporium sinense (isolate SF 470), Monacrosporium appendiculatum (isolate CGI), Arthrobotrys robusta (isolate I 31), Arthrobotrys cladodes (isolate CG 719) and Duddingtonia flagrans (isolate CG 768) were evaluated under laboratory conditions regarding the capacity to entrap infective Cooperia sp. and Oesophagostomum sp. larvae. In the in vitro tests the fungi tested were equally efficient to prey the nematodes (P<0.05) during the five days of the experiment. Reproductive structures (conidia) from all isolates were visualized in 5th day. All fungal isolates were efficient in the control of bovine Cooperia sp. and Oesophagostomum sp. parasites.
