寡孢节丛孢菌和褶生轮枝菌对根结线虫的致病力

PATHOGENICITY OF THE NEMATOPHAGOUS FUNGI ARTHIOBOTRYS OLIGOSPORA AND VERTICILLIUM LAMELICOLA AGAINST ROOT KNOT NEMATODES

寡孢节丛孢菌(Arthiobotrys oligospora)属于捕食性线虫真菌,菌丝上产生的环状捕捉器,可将线虫的头部或尾部套住,即使线虫剧烈挣扎也难逃脱。进而环状菌丝长出芽管,伸入线虫体内吸取营养,菌丝长满体腔,使线虫死亡。褶生轮枝菌(Verticillium lamelicola)是寄生性线虫真菌,对线虫的卵粒和固着寄生线虫均有较强侵染力。
