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.
Nematodes emerging from a wax moth larva cadaver. Entomopathogenic nematodes (EPN) are a group of nematodes (thread worms), that cause death to insects. The term entomopathogenic has a Greek origin, with entomon, meaning insect, and pathogenic, which means causing disease.
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 ...
They range in size from one-celled bacteria, algae, fungi, and protozoa, to more complex nematodes and micro-arthropods, to the visible earthworms, insects, small vertebrates, and plants. As these organisms eat, grow, and move through the soil, they make it possible to have clean water, clean air, healthy plants, and moderated water flow.
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 ...
These organisms include earthworms, nematodes, protozoa, fungi, bacteria, different arthropods, as well as some reptiles (such as snakes), and species of burrowing mammals like gophers, moles and prairie dogs. Soil biology plays a vital role in determining many soil characteristics.
The Chernobyl site in northern Ukraine has been filled with deadly radiation since the 1986 nuclear meltdown, but a new study shows that microscopic worms at the site seem to be unaffected by the ...
Nematodes are considered beneficial because they will help compost and provide nutrients for the soil the plants are growing in. Insects and arachnids help the growing process because they prey on non beneficial organisms that consume plants for food. Fungi help the growing process by using long threads of mycelium that can reach very long ...
