Predatory nematodes include Phasmarhabditis hermaphrodita which is a lethal parasite of gastropods such as slugs and snails. [61] Some members of the genus Steinernema such as Steinernema carpocapsae and Steinernema riobrave are generalist parasites of webworms, cutworms, armyworms, girdlers, some weevils, wood-borers and corn earworm moths.

2025年1月7日 · Nematode, any worm of the phylum Nematoda. Nematodes are among the most abundant animals on Earth. They occur as parasites in animals and plants or as free-living forms in soil, fresh water, marine environments, and even such unusual places as vinegar.

Nematodes are simple roundworms. Colorless, unsegmented, and lacking appendages, nematodes may be free-living, predaceous, or parasitic. Many of the parasitic species cause important diseases of plants, animals, and humans. Other species are beneficial in attacking insect pests, mostly sterilizing or otherwise debilitating their hosts.

2021年9月1日 · Based on feeding apparatus and feeding methods, predatory nematodes can be categorized in four major groups viz., mononchids, diplogasterids, dorylaimids and aphelenchids. This review examines predatory attributes of these groups.

2013年12月27日 · A major function of soil nematodes is that they are biocontrol agents, meaning they can be used to eliminate disease causing nematodes and other organisms. This trait causes predatory nematodes to be a great resource in the battle against soil borne diseases.

Predatory nematodes can be applied in the spring to combat chafer beetles, wireworm, and other soil dwelling beetle larvae. Predatory nematodes are effective against over 250 species of insect pests.

Predeceous nematode reduce population of plant parasitic nematodes and also release nutrients in plant available forms, which enable plants to better withstand nematode burden on the roots.

2021年5月1日 · Based on feeding apparatus and feeding methods, predatory nematodes can be categorized in four major groups viz., mononchids, diplogasterids, dorylaimids and aphelenchids. This review...

2018年3月9日 · Prey searching and feeding mechanisms, prey preferences, ecology, biology and conservation of predatory nematodes and prey resistance and susceptibility to predation are elaborated and supplemented with the list of plant-parasitic nematodes recorded as prey to various species of predatory nematodes.

Predatory nematodes are the hunters of the soil food web, feeding on other nematodes and protozoa. By regulating prey populations, they maintain balance in microbial communities, preventing any group from becoming too dominant.
