Blair, J. M. et al. 1996. Soil invertebrates as indicators of soil quality. In Methods for Assessing Soil Quality , SSSA Special Publication 49, pp. One group of fungi may be a useful biological control agent against parasitic nematodes. These predatory fungi grow through the soil, setting out traps when they detect signs of their prey.
Some species use sticky traps, others make circular rings of hyphae to constrict their prey.
When the trap is set, the fungi put out a lure, attracting nematodes that are looking for lunch. The nematode, however, becomes lunch for the fungus.
