摘　　要：本文应用捕食真菌Ａｒｔｈｒｏｂｏｔｒｙｓｏｌｉｇｏｓｐｏｒａ，Ａ．ｍｕｓｉｆｏｒｍｉｓ，Ａ．ｃｌａｄｏｄｅｓ，Ａ．Ｖｅｒｍｉｃｏｌａ，Ｍｏｎａｃｒｏｓｐｏｒｉｕｍｌｙｓｉｐａｇａ，Ｍ．ｍｅｇａｌｏｓｐｏｒｕｍ，Ｍ．ｍｕｔａｂｃｌｅ，对南方根结线虫（Ｍｅｌｏｉｄｏｇｙｎｅｉｎｃｏｇｎｉｔａ）进行了致病力测定和捕食过程观察，结果表明：各菌株对根结线虫二龄幼虫均具有致病性，Ａｒｔｈｒｏｂｏｔｒｙｓ属菌种以三维粘性菌网捕食，Ａ．ｏｌｉｇｏｓｐｏｒａ捕食率最高；Ｍｏｎａｃｒｏｓｐｏｒｉｕｍ属菌种形成粘着孢和非收缩环两种捕食器官。Pathogenicety of seven predacious fungal species against meloidogyne incognita, loas studied in the laboratory. Testing species are Arthrobotrys oligospora, A, musiformis. A. cladodes, A. Vermicola, monacrosporium lysipaga, M.megalalosporum, M. mutabcle. The results showed all these species had Pathogenicity. A. oligospora (YII110) had more effects than other species,and trappingthe rate for seven days was 99 %. The genus of Arthobotrys produced three dimensional adhesive networks. The genus of Monacrosporium formed organs of adhesive knob and non-constricting ring.
