摘　　要：采用平板分离法分离供试南方根结线虫(Meloidogyneincognita)和北方根结线虫(M.hapla)80余份样品的雌成虫、卵和卵囊上的食线虫菌物,结果共分离鉴定出10属21种天敌菌物。其中棒曲霉Aspergillusclavatus、疏展曲霉A.effusus、赭曲霉A.ochraceus、瓜曲霉A.unguis、禾黑芽枝霉Cladosporiumherbarum、黄绿青霉Penicilliumcitreo-viri de、Ulocladiumatrum、U.oudemansii和Pochoniasuchlasporiavar.catenata9个种或变种为首次报道的根结线虫天敌菌物。明确棒曲霉Aspergillusclavatus、绿黏帚霉Gliocldiumvirens、淡紫拟青霉Paecilomyceslilacinus、黄绿青霉Penicilliumcitreo-viride、Ulocladiumatrum、U.oudemansii、Pochoniachlamydosporiumvar.chlamydosporium和P.chlamydosporiavar.catenulata为根结线虫雌虫的寄生菌物;疏展曲霉Aspergilluseffusus、淡紫拟青霉Paecilomyceslilacinus为根结线虫卵的寄生菌物。More than 160 strains were isolated from more than 80 samples of Root-knot nematodes(Meloidogyne incognita or M. hapla) in Shouguang, Qingzhou, Muping, Laixi and Laiyang of Shandong Province during 2002 and 2003. These were identified as 21 species,10 genera., in which 9 species or varieties, Aspergillus clavatus,A. effuses,A. ochraceus,A. unguis,Cladosporium herbarum,Penicillium citreo-viride,Ulocladium atrum,U. oudemansii and Pochonia suchlasporia var. catenata, were first found to be parasites of the Root- knot nematodes.Among of them,10 species or varieties, Aspergillus clavatus,A. effuses.Gliocldium virens.Paecilomyces lilacinus.Penicillium citreo-viride.Ulocladium atrum.U.oudemansii.Pochonia chlamydosporium var. chlamydosporium and P. chlamydosporia var. catenulata, were tested to be parasitic to eggs and females of root-knot nematodes.
