IN VITRO CONTROL OF INFECTIVE CYATHOSTOMES LARVAE (NEMATODE: CYATHOSTOMINAE) FROM EQUINES USING PREDACIOUS FUNGUS Duddingtonia flagrans, Monacrosporium thaumasium e Arthrobotrys robusta CONTROLE IN VITRO DE LARVAS INFECTANTES DE CIATOSTOMÍNEOS (NEMATODA: CYATHOSTOMINAE) DE EQUINOS UTILIZANDO OS FUNGOS PREDADORES Duddingtonia flagrans, Monacrosporium thaumasium e Arthrobotrys robusta

The predatory capacity of three isolates of the nematodes predacious fungi Duddingtonia flagrans (AC001), Monacrosporium thaumasium and Arthrobotrys robusta on infective larvae of cyathostomes was evaluated in laboratorial conditions in medium water-agar 2% (WA 2%). The isolates AC001, NF34 and I31 had presented significant reduction (pKEY WORDS: Arthrobotrys robusta, Cyathostominae, equine, Duddingtonia flagrans, Monacrosporium thaumasium, Nematophagous fungi. A capacidade predatória de três isolados de fungos predadores de nematoides Duddingtonia flagrans (AC001), Monacrosporium thaumasium (NF34) e Arthrobotrys robusta (I31) sobre larvas infectantes de ciatostomíneos foi avaliada em condições laboratoriais em ensaio experimental em meio ágar-água 2% (AA 2%).
