Rhabditida is an order of free-living, parasitic and microbivorous nematodes living in soil. The Cephalobidae, Panagrolaimidae, Steinernematidae, and Strongyloididae seem to be closer to the Tylenchia, regardless of whether these are merged with the Rhabditia or not. [1]

Subclass Rhabditia is mostly composed of parasitic nematodes (particularly in the Strongylida), though there are some free-living species as well (particularly in the Rhabditida). Phasmids (posterior sensory structures) are well-developed, while amphids (anterior sensory structures) are poorly developed or absent in this group.

Rhabditid nematodes are very abundant in all types of soil and sediments of freshwater. They play important ecological roles mainly as primary consumers—their freeliving forms display saprophagous or bacteriophagous feeding habits—but also as animal parasites, in particular enthomopathogenic forms.

2024年3月1日 · The family Rhabdiasidae (Nematoda: Rhabditida) is a globally distributed group of nematode parasites, with over 110 species parasitic mainly in amphibians and reptiles. However, the systematic position of the family Rhabdiasidae in the order Rhabditida remains unsolved, and the evolutionary relationships among its genera are still unclear.

The Rhabditidae are a family of nematodes which includes the model organism Caenorhabditis elegans. Genus Diploscapter.

Entomopathogenic nematodes are soft bodied, non-segmented roundworms that are obligate or sometimes facultative parasites of insects. Entomopathogenic nematodes occur naturally in soil environments and locate their host in response to carbon dioxide, vibration and other chemical cues (Kaya and Gaugler 1993).

Members of Rhabditina occur predominantly in terrestrial environments (soil, humus, compost, decaying organic matters, dung). The majority of Rhabditina are bacteria-feeding nematodes, which indicate the eutrophic status of running waters and lakes.

The Rhabditida, a group of saprophytic free-living nematodes inhabiting soil, water and decomposing matter, include Strongyloides (see Chapter 117), the most important medically.

The meaning of RHABDITIDA is a large order of Aphasmidia comprising free-living and parasitic nematode worms having the esophagus more or less clearly divided into three regions, usually three or six lips, and the musculature meromyarian or polymyarian.
