Nematodes can effectively regulate bacterial population and community composition—they may eat up to 5,000 bacteria per minute. Also, nematodes can play an important role in the nitrogen cycle by way of nitrogen mineralization. [73] But plant parasitic nematodes cause billions of dollars in annual crop damage worldwide. [74]
Radopholus similis is a species of nematode known commonly as the burrowing nematode. [1] It is a parasite of plants, and it is a pest of many agricultural crops. It is an especially important pest of bananas, and it can be found on coconut, avocado, coffee, sugarcane, other grasses, and ornamentals.
While many plant parasitic nematodes feed on plant roots, foliar nematodes live and reproduce inside the leaves of plants. The nematodes live within the epidermis and mesophyll tissues of leaves, which causes necrosis and collapse of the palisade and spongy parenchyma tissues. Inside the leaves of plants female nematodes lay one or two eggs a ...
Meloidogyne incognita (root-knot nematode, RKN), also known as the southern root-nematode or cotton root-knot nematode is a plant-parasitic roundworm in the family Heteroderidae. This nematode is one of the four most common species worldwide and has numerous hosts. It typically incites large, usually irregular galls on roots as a result of ...
Root-knot nematodes (Meloidogyne spp.) are one of the three most economically damaging genera of plant-parasitic nematodes on horticultural and field crops.Root-knot nematodes are distributed worldwide, and are obligate parasites of the roots of thousands of plant species, including monocotyledonous and dicotyledonous, herbaceous and woody plants.
Pratylenchus brachyurus, like many other plant-parasitic nematodes, are microscopic worms that can be damaging to many agricultural crops.Across the world, many billions of dollars each year are lost due to the damaging abilities of nematodes on cash crops. [1]
They are parasitic on plants and are responsible for root lesion disease on many taxa of host plants in temperate regions around the world. Lesion nematodes are migratory endoparasites that feed and reproduce in the root and move around, unlike the cyst or root-knot nematodes, which may stay in one place.
The mycophagous phase of the life cycle takes place in dead or dying wood, where the nematodes live and feed upon fungi, rather than the wood itself. The nematode cannot travel outside of the wood independently; it must be transported by an insect vector. B. xylophilus has the shortest life cycle of any known parasitic nematode. In laboratory ...
