Plant-parasitic nematodes from the genera Heterodera and Globodera change the morphogenetic programme of plant root cells and induce development of a specific feeding site called a syncytium. The syncytium is the only source of nutrients for developing parasites and functions only for the nematode’s benefit.

Linkage Mapping in Potato Cyst Nematodes
1994A Mendelian proof for a gene-for-gene relationship between virulence in Globodera rostochiensis and the H1 resistance gene from Solanum tuberosum spp. andigena CPC 1673 was obtained by Janssen et al., (1991). It was shown that virulence to the H1 gene is recessively inherited at a single locus.

1986
The soybean cyst nematode (SCN), Heterodera glycines Ichinohe, now infests many soybean producing areas in the USA and will, no doubt, eventually infest every major production area. Ichinohe (1959) reviewed the early history of SCN. It was first reported in Japan in 1915 by Hori (1915), but the nematode had been known for many years prior to that and ...

Nineteen species of cyst nematodes have been recorded from many areas in India since 1958 when the first species, Heterodera avenae Woll. was reported (Vasudeva, 1958). The golden cyst nematode, Globodera rostochiensis (Woll.) Behr., was first discovered by Jones (1961) and since then both G. rostochiensis and G. pallida (Stone) Behr.

Cyst Nematodes (Heteroderidae) From Argentina
Nematologica, 1987An undescribed species of the genus Cactodera Krall & Krall, 1978, was found in uncultivated soil and potato fields in the southeastern region of the Buenos Aires province. The morphology of this Cactodera species is described from cysts and second stages juveniles.

In 1931 Triffit referring to females of a cyst nematode found on roots of carrots (Daucus carota L. ssp. sativus), stated: “These white stage females were rather small and of the lemon-shaped type, and were furnished with a rather larger egg sac than is usual for H. schachtii.

PCR Detection of Potato Cyst Nematode
2008Potato cyst nematode (PCN) is responsible for losses in potato production totalling millions of euros every year in the EC. It is important for growers to know which species is present in their land as this determines its subsequent use. The two species Globodera pallida and Globodera rostochiensis can be differentiated using an allele-specific PCR.

Fungal parasites of cyst nematodes
Agriculture, Ecosystems & Environment, 1988Abstract Cyst nematodes are major pests of a range of crops grown throughout the world. In the last decade it has been demonstrated that nematophagous fungi can effectively control some cyst-nematode pests on crops grown in monocultures. However, such natural control may be slow to establish in soil and difficult to exploit.

Cyst Forming Nematodes in Libya
1986Plant nematology only became established in Libya in the late 1970s but surveys and identifications of several plant parasitic nematodes associated with different crops in Libya were made by foreign scientists, mainly Italians, before then. Carraro (1959) recorded the beet cyst nematode, Heterodera schachtii Schmidt on sugar beet at Sidi El-Mesri ...
