Cyst-forming nematodes are the economical pests of cultivated crops and known to be reported from all the continents (Jones et al., 2013). The genus Heterodera was erected by Schmidt (1871) and currently contains about 80 species (Subbotin et al., 2010). Literature studies have indicated the presence of 14 Heterodera species from China mainland, including H. avenae (Chen et al., 1991), H. glycines (Liu et al., 1994), H. sinensis (Chen and Zheng, 1994), H. filipjevi (Li et al., 2010), H. koreana

A new soybean cyst nematode Heterodera sojae n. sp. was found from the roots of soybean plants in Korea. Cysts of H. sojae n. sp. appeared more round, shining, and darker than that of H. glycines. Morphologically, H. sojae n. sp. differed from H. glycines by fenestra length (23.5–54.2 mm vs. 30–70 mm), vulval silt length (9.0–24.4 mm vs. 43–60 mm), tail length of J2 (54.3–74.8 mm vs. 40–61 mm), and hyaline part of J2 (32.6–46.3 mmvs. 20

The alfalfa cyst nematode, Heterodera medicaginis Kirjanova in the study of Kirjanova and Krall (1971) was originally described from the USSR in 1971 and re-described by Gerber and Maas (1982). The distribution of H. medicaginis is mostly Europe (Russia and Ukraine) and Asia (Kazakhstan and Uzbekistan) (Subbotin et al., 2010). This cyst nematode species can cause up to 46% green matter losses in lucerne under arid conditions (Artokhnica, 1984; Subbotin et al., 2010). More recently, the first

The ascomycete fungus Hyalorbilia aff. multiguttulata DoUCR50 (basionym: Dactylella oviparasitica DoUCR50) is a hyperparasite of the sugarbeet cyst nematode, Heterodera schachtii. It is the causal agent of a long-term population suppression of this nematode in field 9E at the University of California Riverside Agricultural Operations (Borneman and Becker, 2007). Dactylella oviparasitica was re-named Brachyphoris oviparasitica (Chen et al., 2007) and subsequently assigned to the teleomorphic

The cysts forming nematodes of the genus Heterodera Schmidt, 1871 (Nematoda: Heteroderidae) are an economically important plant-parasitic nematode (PPN) group with a worldwide distribution and a broad host range causing prominent damages to the host plants ranging from stunted and reduced growth to wilting, chlorosis, and reduced root system (Perry et al., 2018; Sikora et al., 2018). The vermiform second-stage juveniles (J2) of this PPN migrate in the root system of a host plant to feed on the

Cereal cyst nematode (Heterodera avenae complex; CCN) is found globally and leads to significant economic yield losses, particularly in areas where dryland and cereal monoculture systems are practiced (Nicol et al., 2003; Dababat et al., 2015). After hatching, second-stage juvenile (J2) cyst nematodes start attacking the roots of the plant and begin feeding. The J2s penetrate the root system

Although fig trees are a popular ornamental fruit tree in subtropical regions, some hardy species, such as Ficus carica, have been grown in the west coast of British Columbia and southern Ontario in Canada. The fig cyst nematode, Heterodera fici Kirjanova, is a pest on fig plants, and the heavy infestation can cause retarded growth and yellowing of leaves (Maqbool et al., 1987). In the spring of 2016, a sample of rhizosphere from a potted fig (F. carica) seedling was submitted to the

Two nematodes of major concern for soybean production in Arkansas include the soybean cyst nematode (Heterodera glycines, Ichinoe) and the southern root-knot nematode (Meloidogyne incognita, Kofoid & White, Chitwood). Both nematodes have been historically present in Arkansas soybean and cotton fields (Kirkpatrick et al., 1992; Bateman et al., 2000; Walter and Barker, 1994; Tylka and Marett, 2014).

The soybean cyst nematode (SCN), Heterodera glycines, is an obligate plant parasite that poses a serious threat to soybean production worldwide. It is the most damaging pest of soybean in the USA and is estimated to cause more yield loss than any other disease (Koenning and Wrather, 2010; Wrather et al., 2010; Allen et al., 2017). Yield losses are attributed to the fact that this nematode injects a complex mixture of proteins and metabolites into the plant root cells (Niblack et al., 2006) and

Soybean cyst nematode (SCN, Heterodera glycines Ichinohe) is a serious soybean pathogen worldwide. HG Type 0 had been a predominant SCN in Heilongjiang province, the largest soybean (Glycine max L.) producing region in China. Recently, increased virulence on resistant cultivars originally developed for resistance to HG Type 0 was observed in fields. In order to identify new cultivars resistant to local SCN populations, two soil samples were collected from two counties (Anda and Wuchang) in

The results demonstrated that ALA exhibited a strong effect of suppression against the four nematodes tested. ALA also inhibited hatching of M. incognita and H. glycines. Results from the greenhouse experiment indicated that treatment of soil with 6.0 mM ALA significantly reduced the root-gall index (RGI) and

During 2008 to 2016 in several nematological surveys in the Tepeaca Valley, Puebla, Mexico, carrot cyst nematode, Heterodera carotae was found parasitizing carrots, Daucus carota. The nematode was present in 61% of the sampled fields with high population densities, causing severe carrot yield losses in the Tepeaca Valley. The aim of this work was to study morphology, morphometrics, host range, and molecular characterization of the nematode. The morphological and morphometric characterization

). In contrast, it is widely accepted that PPN selectively target host, but not non-host, plant roots (Nicol et al., 2011). The most well characterized target selectivity of nematodes was described using maize roots and an entomopathogenic nematode, Heterodera megidis (Rasmann et al., 2005). In response to the feeding of western corn rootworm (WCR) larvae, maize roots emit a volatile compound (E)-β-caryophyllene to strongly attract H. megidis which in turn parasitizes and kills WCR larvae within a

Soybean cyst nematode (SCN), Heterodera glycines Ichinohe, is widely distributed throughout most soybean producing regions in the world (Riggs, 2004). This nematode has become a major yield-limiting factor in soybean production and causes an estimated annual yield loss of about $1 billion in the USA (Koenning and Wrather, 2010). Crop rotation, cultural practices, resistant cultivars, and nematicides are employed to reduce soybean yield suppression caused by SCN. Particularly, rotation of SCN

management of plant-parasitic nematodes is necessary to optimize crop productivity (Grabau and Chen, 2016a, 2016b) and non-parasitic, free-living nematodes contribute to and are sensitive indicators of soil fertility and ecology (Bongers, 1990; Ferris et al., 2001).
In particular, soybean cyst nematode (Heterodera glycines) is the major yield-limiting pest in soybean production (Koenning and Wrather, 2010). Additional strategies to manage this pest are needed because management relies on a narrow set of
