摘　　要：利用水琼脂平板法测定分离于南方根结线虫卵囊的绮丽小克银汉霉对南方根结线虫游离卵及卵囊中的卵寄生性.结果发现,绮丽小克银汉霉对平板上游离卵的寄生性低,寄生率为21.1%;完整卵囊接种菌后,菌丝可定殖于卵囊表面,但卵囊内的卵未见被寄生.本试验对绮丽小克银汉霉作为生防菌的应用可能性进行了探讨.An isolate of Cunninghamella elegans from egg masses of Meloidogyne incognita was evaluated in vitro for parasitism of separated eggs or egg mass of M. incognita on water agar. The results showed that the percentage of separated eggs parasitized by C. elegans was 21.1% on average, eggs in intact egg mass were not parasitized even the fungi colonized on egg mass. The possibility of C. elegans being used as biocontrol fungi was discussed.
