In Vitro Nematophagous Activity of Predatory Fungi on Infective Nematodes Larval Stage of Strongyloidae Family

AIM: The main goal of the present research conducted to assess the in vitro activity of the nematophagous fungi Duddingtonia flagrans, Fusarium solani, Verticillium chlamidosporium, and Trichoderma harzianum. MATERIAL AND METHODS: Four isolates of fungi including D. flagrans, F. solani, V. chlamidosporium and T. harzianum were used in this study. Horse faeces were used to provide the larvae stage of Strongyloidae family for the experiments. RESULTS: D. flagrans was the most effective fungus to reduce the population of the larval nematodes. D. flagrans was able to kill 100% of larvae after 14 days of incubation. The significant effect was seen after 7 days of incubation, therefore, the live larvae was decreased to 9, 11, 19 and 25 for D. flagrans, V. chlamidosporium, F. solani and T. harzianum, respectively. CONCLUSION: Our results illustrated that D. flagrans were most successful fungus for reducing the number of Strongylidae family larva stage from horse faeces. Follow D. flagrans, the live larvae was significantly reduced for V. chlamidosporium, F. solani and T. harzianum, respectively.
