Heterorhabditis bacteriophora is a species of entomopathogenic nematode known commonly as beneficial nematodes. They are microscopic and are used in gardening as a form of biological pest control . They are used to control ants , fleas , moths , beetles , flies , weevils , and other pests.
They are highly diverse, complex and specialized. The most commonly studied entomopathogenic nematodes are those that can be used in the biological control of harmful insects, the members of Steinernematidae and Heterorhabditidae. They are the only insect-parasitic nematodes possessing an optimal balance of biological control attributes.
Soil steaming is an efficient method to kill nematodes before planting a crop, but indiscriminately eliminates both harmful and beneficial soil fauna. The golden nematode Globodera rostochiensis is a particularly harmful pest that has resulted in quarantines and crop failures worldwide.
Certain microscopic nematodes (worms) are beneficial in destroying and controlling populations of larvae that are damaging or deadly to crops and other plants. They are commonly used in organic gardening for their ability to kill various kinds of harmful larvae ( fungus gnats , flea larvae, spidermites , weevils , grubs , wireworms , cutworms ...
Mermithidae is a family of nematode worms that are endoparasites in arthropods. As early as 1877, Mermithidae was listed as one of nine subdivisions of the Nematoidea. [2] Mermithidae are confused with the horsehair worms of the phylum Nematomorpha that have a similar life history and appearance. Mermithids are parasites, mainly of arthropods ...
[17] [22] These nematodes, including the feltiae species, are parasites that can attack the larvae stage of fungus gnats. [ 23 ] Mites of the species Stratiolaelaps scimitus (formerly known as "Hypoaspis miles") have also been shown to be effective at controlling fungus gnats. [ 17 ]
As the worms developed ways of triggering a beneficial immune response, humans came to rely on parasitic interaction to help regulate their immune systems. As developed countries advanced in technology, medicine, and sanitation, parasitic worms were mostly eradicated in those countries, according to Weinstock in the medical journal Gut. [16]
Soil Macrofauna, earthworms, termites, ants, and some insect larvae, can make the pore spaces and hence can change the soil porosity, [5] one aspect of soil morphology. Mesofauna contribute to habitable pore spaces and account for a small portion of total pore spaces. Clay soils have much smaller particles which reduce pore space. Organic ...
