Heterodera avenae, the cereal cyst nematode or European cyst nematode, is a plant pathogen and an obligate parasite of cereal crops including barley, oats, wheat and rye. Cereal crops infected with this nematode are more susceptible to infection by fungal diseases such as rhizoctonia root rot.
Heterodera cajani is a plant pathogenic nematode affecting pigeonpeas, who is cited as an invasive species.
Heterodera carotae is a plant pathogenic nematode commonly known as the carrot root nematode or carrot cyst nematode. It is found in Europe, Cyprus and India and is considered an invasive species in the United States. It causes damage to carrot crops and is very specific in its choice of hosts, only infecting Daucus carota and Daucus pulcherrima.
Heterodera goettingiana, the pea cyst nematode, is a plant pathogenic nematode affecting pea found in the United kingdom.
Heterodera humuli is a plant pathogenic nematode, the hop cyst nematode. It is an obligate parasite and infests hop plants, Humulus lupulus.
Heterodera latipons, the Mediterranean cereal cyst nematode or wheat cyst nematode, is a plant pathogenic nematode.
Heterodera schachtii, the beet cyst eelworm or sugarbeet nematode, is a plant pathogenic nematode. It infects more than 200 different plants including economically important crops such as sugar beets, cabbage, broccoli, and radish. H. schachtii is found worldwide. Affected plants are marked by stunted growth, wilting, yellowing, decreased yields, and death. While there are many methods of control, crop rotation with non-susceptible plants is preferred.
Heterodera is a genus of nematodes in the family Heteroderidae. Members of the genus are obligate parasites and different species attack different crops, often causing great economic damage. The genus is unique among nematode genera because of the ability of the female to transform into a tough, brown, cyst which protects the eggs which have been formed within her body. The name heterodera "refers to the different 'skins' of female and cyst."
Heterodera sacchari, the sugarcane cyst nematode, mitotic parthenogenic sedentary endoparasitic nematode. This plant-parasitic nematode infects the roots of sugarcane, and the female nematode eventually becomes a thick-walled cyst filled with eggs. Aboveground symptoms are species specific and are similar to those caused by other Heterodera species. Symptoms include: stunted and chlorotic plants, and reduced root growth. Seedlings may be killed in heavily infested soils.
Heterodera bifenestra is a plant pathogenic nematode, that is a causal agent of the cereal cyst nematode.
Heterodera oryzae, the rice cyst nematode, is a plant pathogenic nematode, which is cited as an invasive species.
Rice cyst nematode is the common name for several species of invasive plant-pathogenic nematodes:
Heterodera medicaginis, the alfalfa cyst nematode, is a plant pathogenic nematode which is cited as an invasive species. It is closely allied to Heterodera daverti, H. glycines and H. sonchophila in the H. schachtii-group. The only known host plant of this obligate parasite is the important crop alfalfa or lucerne, Medicago sativa.
Heterodera oryzicola, the rice cyst nematode, is a plant pathogenic nematode, which is cited as an invasive species.
Heterodera delvii is a plant pathogenic nematode, who is cited as an invasive species.
Heterodera elachista, the Japanese cyst nematode or rice cyst nematode, is a plant pathogenic nematode, which is cited as an invasive species.
Heterodera zeae, the corn cyst nematode (CCN), is a plant parasitic nematode that feeds on Zea mays (maize/corn). The CCN has a limited economic impact worldwide due to its high soil temperature requirements.
Pasteuria nishizawae is a mycelial and endospore-forming bacterium parasitic on cyst nematodes of genera Heterodera and Globodera.
Thalthana is a village in the north of Syria, about 40 km north east of Aleppo and part of the Aleppo Governorate, near the Turkish border. Kurds are the majority of the population of the village.
