Potato Cyst Nematode: One Species or Two ?

Nature, 1970
THE potato or golden cyst nematode, Heterodera rostochiensis Woll., is an important pest of potatoes and tomatoes but has never been fully described. It belongs to the group of species of Heterodera1,2 which have round cysts and do not produce an egg sac3, for which the sub-generic name Globodera was suggested4. This group includes H. tabacum Lownsbery

Potato cyst nematodes on tomato

1992
Potato cyst nematodes, well known as pests of potato (see page 422), are also serious pests of tomato. For many years they have been established in the main tomato-growing areas of England and Wales. Intensive growing of tomatoes in soil, either under glass or outdoors, can easily lead to nematode populations building up to a damaging level unless ...

The population dynamics of potato cyst nematodes

Ecological Modelling, 2007
The article provides a mathematical description based on the theory of differential equations, for the population dynamics of the parasite potato cyst nematodes (PCN). Parameters to the model are estimated from published data. We study different strategies to counter attack pest of PCN faced by potato producers. The relation between initial PCN density,

Glutathione peroxidases of the potato cyst nematode Globodera Rostochiensis

Gene, 2004
We report the cloning and characterisation of full-length DNAs complementary to RNA (cDNAs) encoding two glutathione peroxidases (GpXs) from a plant parasitic nematode, the potato cyst nematode (PCN) Globodera rostochiensis. One protein has a functional signal peptide that targets the protein for secretion from animal cells while the other is predicted

Current Status of Potato Cyst Nematodes in North America

Annual Review of Phytopathology, 2019
The potato cyst nematodes (PCNs) Globodera rostochiensis and Globodera pallida are internationally recognized quarantine pests. Although not widely distributed in either the United States or Canada, both are present and are regulated by the national plant protection organizations (NPPOs) of each country. G.

Modelling multigenic resistance to potato cyst nematodes

EPPO Bulletin, 1985
After making simplifying assumptions, the ability of female potato cyst nematodes to develop and reproduce is modelled by expressions of the type ix·x and ix·(1 ‐ x), where x is the frequency within a population of females able to circumvent the effects of a real resistance gene. Such females are potentially able to develop to maturity and reproduce to

Modelling the interaction between potato crops and cyst nematodes

1995
Simulation modelling of the effects of cyst nematodes on potato crop growth is still in its infancy. The first attempts to simulate nematode population dynamics together with host growth were done in the 1970s. For many years the models focussed on the rate of growth of the nematode population, while using oversimplified, descriptive functions for host

Agronomic Aspects of Potato Cyst Nematode Infestation

1986
Potato cyst nematodes, Globodera rostochiensis (Woll.) Behr. and Heterodera pallida (Stone) Behr., are present in most potato growing areas throughout the world (Evans and Stone, 1977). They seem particularly adapted to Western and Central European conditions.

The Canon of Potato Science: 14. Cyst Nematodes

Potato Research, 2007
Cyst forming nematodes, or cyst nematodes, are one of the most specialized and successful plant-parasitic nematode pests of agriculture. The nematodes have a very narrow host range, which is opposite to root-knot nematodes which are polyphagous. In the case of potato, only the potato cyst nematodes (PCN) Globodera rostochiensis and G.
