Species of nematode-trapping fungi isolated from three paddy fields and three fish ponds around Dianchi Lake in Yunnan province were compared. Those isolated from the fish ponds were fewer than those from the paddy fields and the dominant species in the two eco-environments were not the same. In the paddy fields Arbrostrys conoides was dominant in spring and fall and A. oligospora was dominant in summer and winter. Further in fall, species of nematode-trapping fungi were the most, then in spring, in summer and win- ter. However,in the fish ponds, Dactylellina ellipsosporum was dominant in spri...
