Free-living nematodes can be divided into four broad groups based on their diet. They eat some harmful species of bacteria, fungi, and even the larvae of insects. At low nematode densities, feeding by nematodes stimulates the growth rate of prey populations. nematode densities, feeding by nematodes stimulates the growth rate of prey populations. pore spaces. Because they eat bacteria and fungi, some microbivorous nematodes adopt the role of hygiene police for nest-building insects. if the bees are directly sprayed, or eat from a sprayed flower). Publication 49, pp. You probably do not have the root knot guys as they like warmer climates like we have here in KS. fungal biomass; root-feeders are concentrated around roots of stressed or susceptible There are some insects that nematodes can kill in a lab setting, but due to challenges associated with application we do not advertise our nematode products as good controls for those pests (such as ticks). Because of the wide range of feeding types and the fact that they seem to reflect ages of the systems in which they occur, i.e., annual vs perennial crops, old fields and pastures, and more mature forests, nematodes have been used as … Root-feeders are plant parasites, and thus are not free-living in the soil. Nematodes can effectively regulate bacterial population and community composition—they may eat up to 5,000 bacteria per minute. This phoretic relationship can be quite specific and does not seem to harm the carrier, while it is essential for the nematodes. This accounts for the majority of nematodes found in marine habitats. Fungal-feeding nematodes are known to feed preferentially on different fungal species (Mankau and Mankau, 1963), including mycorrhizas and yeasts.
