Wie Wurmhumus Schädlinge unterdrückt:

Pflanzen die mit anorganischen Düngemitteln angebaut sind, sind anfälliger für Schädlingsbefall als die Pflanzen, die mit organischem Dünger gedüngt werden:

  1. Culliney TW, Pimentel D (1986) Ecological effects of organic agricultural practices on insect populations. Agric Ecosyst Environ 15:253-256
  2. Yardim EN, Edwards CA (2003) Effects of organic and synthetic fertilizer sources on pest and predatory insects associated with tomatoes. Phytoparasitica 31:324-329

Anorganische Stickstoffdüngung verbessert die Schmackhaftigkeit der Wirtspflanzen für Schädlinge und  hemmt die Produktion der sekundären Stoffwechselprodukte (Metaboliten):

  2. Herms DA (2002) Effects of fertilization on insect resistance of woody ornamental plants. Environ Entomol 31:923-933

Die Anwendung von anorganischem Dünger zieht mehr Insekten zur Eiablage an und erhöht ihre Fruchtbarkeit und Bevölkerungswachstumsraten::

Wurmkompost als organischer Dünger hat ein langsames, ausgewogenes Nahrungsfreisetzungsmuster vor allem in Freisetzung von Verfügbarem N, löslichem K, austauschbarem Ca, Mg und P. Die Pflanzen haben einen verringerten Stickstoffgehalt und höheren Phenolgehalt, was zum Widerstand dieser Pflanzen gegen Schädlingsbefall führt:

Wurmhumus ist reich an Huminsäuren und Phenolverbindungen. Die Aufnahme von löslichen phenolischen Verbindungen von Wurmkompostin in den Pflanzengeweben macht sie für Schädlinge ungenießbar und  verringert die Fortpflanzung und das Überleben von Schädlingen:
