In vitro observation of the action of isolates of the fungi Duddingtonia flagrans, Monacrosporium thaumasium and Verticillium chlamydosporium on the eggs of Ascaris lumbricoides (Linnaeus, 1758)

Abstract

The in vitro action of the nematophagous fungi Duddingtonia flagrans, Monacrosporium thaumasium and Verticillium chlamydosporium on eggs of Ascaris lumbricoides was observed. After 7, 10 and 14 days of interaction, the fungus showing most promise for use in biologically control over Ascaris lumbricoides was Verticillium chlamydosporium (26-30%). The other fungi did not present satisfactory results.
