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...

| Summary: | 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 (p<0.01) de 97.5%, 72.5% e 85% respectively in the average of infective larvae of ciathostomes recovered of the medium WA2% in the end of five days. The results of this assay evidence that these isolates could be used in the biological control of ciathostomes of equines.<br /><br />KEY WORDS: Arthrobotrys robusta, Cyathostominae, equine, Duddingtonia flagrans, Monacrosporium thaumasium, Nematophagous fungi.<br /> <p class="MsoNormal" style="margin: 0cm 0cm 0pt; line-height: 150%; text-align: justify; tab-stops: 243.0pt">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%). Os isolados AC001, NF34 e I31 apresentaram redução significativa (p<0,01) de 97,5%, 72,5% e 85%, respectivamente, na média de larvas infectantes de ciatostomíneos recuperadas do meio AA2% ao final de sete dias. Os resultados deste ensaio evidenciam que esses isolados poderão ser utilizados no controle biológico de ciatostomíneos de equinos.<br /> <br />PALAVRAS-CHAVES: Arthrobotrys robusta, ciatostomíneos, equinos, Duddingtonia flagrans, fungos nematófagos, Monacrosporium thaumasium.</p> |
