Chhattisgarh isolates of Arthrobotrys oligospora and Duddingtonia flagrans were screened for their growth at 26°C, nematode capturing ability, ability to produce chlamydospores and their rate of germination. Further, the fungal ability to survive animal gut passage by in vitro growth assay, larval bait assay, and grain cultures and attempting to reisolate the same fungus by copro-culture assay following feeding of spores to monogastric and polygastric animals was also assessed. A. oligospora was found superior in growth rates at 26°C and was more vigorous than D. flagrans in nematode capturing ability. However, only D. flagrans has the ability to produce chlamydospores and the fungus could be reisolated from the faeces of goat and pig after 36 and 24 h of chlamydospores feeding, respectively.
