Entomopathogenic nematodes (EPNs) live parasitically inside the infected insect host, and so they are termed as endoparasitic. They infect many different types of insects living in the soil like the larval forms of moths, butterflies, flies and beetles as well as adult forms of beetles, grasshoppers and crickets. EPNs have been found all over ...
The CCN is a sedentary endoparasitic nematode, establishing feeding sites in the roots of host plants near the vascular tissue. Like other cyst nematodes, CCN feeds from a specialized feeding site known as a syncytium. This feeding site is formed by the deterioration of cell walls of adjoining plant cells in response to elicitors delivered ...
Heterodera sacchari, [1] [2] the sugarcane cyst nematode, mitotic parthenogenic sedentary endoparasitic nematode. This plant-parasitic nematode infects the roots of sugarcane , and the female nematode eventually becomes a thick-walled cyst filled with eggs.
This root-knot nematode is sedentary endoparasitic nematode. Second-stage juveniles (J2) penetrate host roots where they establish a specialized feeding site (giant cells) in the stele. As J2 develop, they cause root swellings and become swollen females. Females rupture root cortex and sometime protrude with the egg masses from the root surface.
Females are swollen, pear-shaped pearly white and sedentary. They deposit their eggs in a gelatinous mass, which usually protrudes from galled root tissue. Females of this nematode are completely endoparasitic. [10] Mature females of M. arenaria are identified by the cuticular markings in the perineal area, stylet length, punctations on the ...
In terms of feeding strategy, Nacobbus is classified as a false root-knot nematode because it is both migratory endoparasitic and sedentary endoparasitic. [4] It is the only known nematode to do so; all others employ either one strategy or the other. In Nacobbus, each strategy is employed at different stages in the life cycle. [5]
The nematode Caenorhabditis elegans an important model organism, was used as part of an ongoing research project conducted on the 2003 Space Shuttle Columbia mission STS-107, and survived the re-entry breakup. It is believed to be the first known species to survive a virtually unprotected atmospheric descent to Earth's surface.
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 ...
