Nematode Infected Grub


Steinernema carpocapsae Nematode



  • Larvae of soil and leaf-dwelling pests from the families of Noctuidae (noctuids)
  • Larvae of Pyralidae (e.g. Duponchelia fovealis)
  • Larvae of Tipulidae (crane flies)
  • Larvae of the great pine weevil (Hylobius abietis)
  • Also effective against the larvae of various pests belonging to the orders Coleoptera (beetles) and Orthopthera (e.g. mole crickets)
  • Larvae of Capnodis tenebrionis


Environmental conditions

  • The moisture content of the soil must be high
  • Soil temperature between 14 and- 33°C
  • Nematodes are very susceptible to ultraviolet light (UV): do not use them in direct sunlight
  • Leaf applications should be carried out in the evening to minimise the influence of UV light and maximise moisture availability for the nematodes


Mode of action

After application, the nematodes actively search for their prey and penetrate them. The nematodes then feed on the contents of the prey, excreting specific bacteria from their digestive tracts as they do so. These bacteria convert the host tissue into products that the nematodes can easily ingest. The larvae die within a few days.

Visible effects

Affected insect larvae change colour and become slimy.
