补充资料:捕食性真菌
      寄生在线虫、变形虫、轮虫等小动物上的真菌。它包括形成或不形成捕捉器官的种。狭义的捕食性真菌指能形成捕捉器官或分泌粘性物质的真菌。如捕虫霉目的无柄霉属、梗丛霉属和泡囊虫霉属;丝孢目的肋孢属、隔指孢属和节丛孢属;水霉目的轮虫水霉属的一些种。壶菌目的囊壶菌属。根生壶菌属,虫霉目的擒虫霉属,丝孢目的杀虫孢属的一些种不形成任何捕捉器官,而是靠孢子经寄主的口腔感染。
  
  捕食性真菌广布于有机残体、粪堆、朽木、土壤或水体中,在苔层下面特别多。它们在捕捉线虫时有粘捕和套捕两种方法;前者又称化学捕捉法,后者又称物理捕捉法。粘捕法是靠分泌粘性物质的菌网、菌钮、菌枝、菌丝和孢子粘捕猎物,例如囊胞顶孢霉形成稠密、粘着的捕食网,椭圆隔指孢形成多粘液的菌钮、菌丝和孢子。套捕法是靠菌套套捕线虫,例如绞套节从孢可形成能收缩的菌套,从而套住线虫;白指孢形成的菌套不能收缩,它是靠整体进行捕捉的。捕虫真菌在粘住或套住线虫以后,与线虫接触处便长出一根细小的穿透枝,它穿透线虫的体壁,在线虫体内形成侵染球,从侵染球再长出充满线虫体腔的营养菌丝,吸收线虫体液作为养料。
  
  利用捕食性真菌防治寄生性线虫等的危害,还待研究与开发。
