DiTera® (Valent BioSciences Corp.), a novel biological nematicide obtained from fermentation with a hyphomycete fungus, adversely affected activity and movement through sand columns of second stage juveniles (J2) of Globodera rostochiensis. Electrophysiological tests demonstrated that exposure to 1% DiTera® prevented sensory perception of potato root diffusate. Electropharyngeograms of stylet protractor muscle activity showed that prior exposure of fourth stage juveniles of Ditylenchus dipsaci…

Effects of biologically-derived products on mobility and reproduction of the root-lesion nematode, Pratylenchus penetrans, on strawberry.
TLDR
Data suggest that multiple applications synchronized with host and nematode biology will be necessary to maintain efficacious concentrations of these biological products in agricultural soils.
Behavioural quiescence reduces the penetration and toxicity of exogenous compounds in second-stage juveniles of Heterodera glycines
TLDR
This research is the first report of behavioural quiescence correlated with reduced sensitivity to toxins in a plant-parasitic nematode, and provides insight into how these important organisms cope with stress due to exogenous toxins.
Bio-activity of fungal culture filtrates against root-knot nematode egg hatch and juvenile motility and their effects on growth of mung bean (Vigna radiata L. Wilczek) infected with the root-knot nematode, Meloidogyne incognita
TLDR
Culture filtrates of selected soil fungi exhibited variable response to egg hatching and mortality of the root-knot nematode, Meloidogyne incognita, and proved to be toxic to the juveniles of M. incognitas.
Evaluation of a novel nematicide for use in the management of the potato cyst nematode, Globodera pallida
The potato cyst nematodes (PCN) Globodera rostochiensis and Globodera pallida are two economically important potato pests constituting major limiting factors to production of the crop in…
Electrophysiological analysis of sensory responses and stylet activity of second stage juveniles of Globodera rostochiensis, and plant reactions to nematode invasion
TLDR
Electrophysiological techniques have been used to examine nematode sensory responses and stylet protractor muscle activity, and the electrical signals generated in plants in response to nematodes invasion, with second-stage juveniles of Globodera rostochiensis.
Effects of Myrothecium verrucaria ZW-2 fermentation filtrates on various plant-parasitic nematodes
TLDR
The results suggested that the fermentation filtrate of M. verrucaria inhibited hatching of Meloidogyne incognita and Heterodera glycines eggs and nematicidal effects against three plant-parasitic nematodes were confirmed.
Introduction to Plant-Parasitic Nematodes; Modes of Parasitism
TLDR
This introductory chapter provides background information about the life-cycle biology of plant-Parasitic nematodes, their different feeding strategies and aspects of the host-parasitic interactions.
Activity of fungal culture filtrates against soybean cyst nematode and root-knot nematode egg hatch and juvenile motility
TLDR
This study identified fungal isolates capable of producing compounds active against these nematodes, and demonstrated that there was a low correlation in activity against SCN and RKN.
Bionematicides as an alternative to methyl bromide fumigation
TLDR
Bionematicides can improve yield, growth, and vigor in walnut orchards infested with plant-parasitic nematodes.
Cyst nematode bio‐communication with plants: implications for novel management approaches
TLDR
Cyst nematode hatching and successful infection of hosts are biological processes that are largely influenced by semiochemicals including hatching stimulators, hatching inhibitors, attractants and repellents, which can be used to disrupt interactions between host plants and cyst Nemesis.
