In addition to the harmful plant parasitic forms, there are groups of nematodes which are beneficial as they parasitize the harmful insects and mollusks and thus can be exploited as biological control agents against these pests. The entomopathogenic nematodes Steinernema and Heterorhabditis spp. and slug parasitic nematode Phasmarhabditis hermaphrodita in a mutual association with bacteria have proved to be successful biocontrol agents and are now being commercially produced in many countries. |
