title: Field experiments on the ability of Arthrobotrys oligospora (Hyphomycetales) to reduce the number of larvae of Cooperia oncophora (Trichostrongylidae) in cow pats and surrounding grass.
abstract: In field experiments, conducted on parasite-free grass plots in two consecutive summers, artificially prepared cow pats containing Cooperia oncophora eggs were inoculated with the nematode-trapping fungus Arthrobotrys oligospora. Numbers of infective C. oncophora larvae isolated from the pats as well as from the surrounding herbage were subject to an approximately ten-fold reduction as compared with numbers in fungus-free pats and herbage surrounding these. This reduction was undoubtedly a result of entrapment of the parasite larvae within the faecal pats.
