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]
The length of the life cycle is temperature-dependent. [16] [17] The relationship between rate of development and temperature is linear over much of the root-knot nematode life cycle, though it is possible the component stages of the life cycle, e.g. egg development, host root invasion or growth, have slightly
Tylenchulus semipenetrans, also known as the citrus nematode or citrus root nematode, is a species of plant pathogenic nematodes and the causal agent of slow decline of citrus. T. semipenetrans is found in most citrus production areas and diverse soil textures worldwide. Their feeding strategy is semi-endoparasitic and has a very narrow host ...
The nematodes migrate to feed on reproductive structures eventually settling in the developing rice seed. As the kernel dries the nematode slowly desiccates and can remain viable in the kernel for up to three years. The life cycle of A.besseyi is generally short consisting of around 8–12 days. [4] [6] This species is thermophilic. The lower ...
Trichinella spiralis life cycle. Female Trichinella worms live for about six weeks, and in that time can produce up to 1,500 larvae; when a spent female dies, she passes out of the host. The larvae gain access to the circulation and migrate around the body of the host, in search of a muscle cell in which to encyst. [3]
Steinernema is a genus of nematodes in the family of Steinernematidae. [ 2 ] [ 3 ] [ 4 ] The genus Steinernema is named after the nematologist Gotthold Steiner . [ 5 ] Nematodes of this genus have been shown to be effective as a biological control for agricultural pests of the Scarabaeidae family, such as Maladera formosae .
Cyst nematodes are monocyclic because they have one life cycle per season. Potato cyst nematodes can be detected by their patchy distribution in the field. The specific distribution is caused by the limited spread of these nematodes. Most potato cyst nematodes don’t migrate very far across a field because of their feeding patterns. [2]
