Management strategies for control of soybean cyst nematode and their effect on the nematode community
Soybean cyst nematode (SCN), Heterodera glycines, is the major yield-limiting pathogen on soybean and various plant-parasitic nematodes can damage corn. Additionally, the nematode community is a useful bioindicator for soil health. In chapter 1, relevant research is reviewed. Chapter 2 describes …

Automated soybean cyst nematode extraction unit
The soybean cyst nematode (SCN) is a plant parasitic roundworm of soybeans responsible for an estimated $0.7-1.2 billion reduction in annual yield loss. In order to manage yield loss due to SCN, soybean producers employ a nematode management plan which utilize extensive soil sampling to assess SCN …

Identification and Characterization of Novel Caenorhabditis Nematode Viruses
… viruses that naturally infect Caenorhabditis nematodes.This dissertation encompasses the identification and characterization of the first viruses known to naturally infect C. elegans and its closest known relative, C. briggsae. Using Next generation 454 pyrosequencing, a novel virus (Orsay …

Exploiting entomopathogenic nematode neurobiology to improve bioinsecticide formulations
Entomopathogenic nematodes (EPNs) are soil dwelling organisms that target and kill insects. They have sophisticated chemosensory apparatus, with which they perceive host associated cues to locate them. Once a suitable host is located, they employ a diverse range of host finding behaviours to …

A study of nematode parasites of some California salamanders
<p>Little information is available concerning the nematode parasites of salamanders in California. Lehmann (1954) reported the finding of Oxyuris dubia Leidy 1856, in the rectum of 33 Ensatine e. Eschscholtzii from Sonoma County, California, and in 3 of 10 Batrachoseps a. Attenuatus, from San …

Interactions and epidemiology of nematode worm control in livestock
… anthelmintics for the treatment of parasitic nematode diseases. This has resulted in widespread resistance to multiple anthelmintic classes across several parasitic genera. In response to this spread in resistance and subsequent decrease in efficacy there has been increased interest in the use …

The ecological impacts of a novel nematode control agent
Plant-parasitic nematodes are prevalent in many soils and impose an economic burden worldwide on agriculture, through yield reductions and cost of control. There is a prominent need for the development and implementation of sustainable control mechanisms, to reduce the widespread use of hazardous …

The Long-Rage Directional Behavior of the Nematode C. Elegans
<p>Like any mobile organism, C. elegans relies on sensory cues to find food. In the absence of such cues, animals might display defined search patterns or other stereotyped behavior. The motion of C. elegans has previously been characterized as a sinusoid whose direction can be modulated by gradual …

The feeding apparattus [sic] of the nematode parasite Globodera pallida
Nematodes are structurally simple animals known commonly as roundworms or thread worms. They are cylindrical non-segmented cigar shaped organisms distinguishing them from other types of worm. However, despite this simplicity these helminths are the most ubiquitous animals on earth and have …

Molecular characterization of CLE peptide mimicry during cyst nematode pathogenesis
… AT AUTHOR'S REQUEST.] Plant-parasitic cyst nematodes establish intimate parasitic relationships with their hosts by penetrating the root as motile juveniles and migrating intracellularly until they reach the root vasculature where they select a single cell to initiate a feeding site known as …
