Abstract:
Plant-parasitic nematodes (PPNs) are significant pests that result in considerable economic losses in global crop production. Due to the high toxicity of chemical nematicides, there is a need to develop new strategies for nematode control. In this context, nematophagous fungi may offer a viable option for biological control. Two fungal strains (GUCC2212 and GUCC2232) were isolated from cysts of Globodera sp., identified as Neocosmospora stercicola . The fungal filtrates of the strains were evaluated for their nematicidal activity against three species of PPNs: Aphelenchoides besseyi , Bursaphelenchus xylophilus and Ditylenchus destructor . The fermentation filtrates of two strains exhibited substantial toxicity towards the evaluated nematodes, with mortality rates reaching up to 100% within 72 h. Concurrently, N. stercicola also demonstrated predatory and parasitic behavior. The eggs of Globodera sp. were parasitized by the two strains. N. stercicola represents a newly recorded species in China and a novel nematophagous species. In conclusion, the two strains of N. stercicola show promise as biocontrol agents for PPNs management.
