The soybean cyst nematode (SCN), Heterodera glycines, is a serious economic threat to soybean-producing regions worldwide. A new SCN population (called race X12) was detected in Shanxi province, China. Race X12 could reproduce on all the indicator lines of both race and Heterodera glycines (HG) type tests. The average number of females on Lee68 (susceptible control) was 171.40 with the lowest Female Index (FI) 61.31 on PI88788 and the highest FI 117.32 on Pickett in the race test. The average

Soybean (Glycine max, Family Leguminosae) is widely grown worldwide due to its unique property of possessing high plant-based protein contents, lipid minerals, and vitamins (Olaoye and Ade-Omowaye, 2011). Soybean cyst nematode (SCN, Heterodera glycines) infection is the most serious disease affecting soybean production worldwide; this infection was reported for the first time in 1899 in Northeast China, since then, this nematode has been spread widely in various regions, including Asia, America

With recently discovered soybean cyst nematode (SCN) viruses, biological control of the nematodes is a theoretical possibility. This study explores the question of what kinds of viruses would make useful biocontrol agents, taking into account evolutionary and population dynamics. An agent-based model, Soybean Cyst Nematode Simulation (SCNSim), was developed to simulate within-host virulence evolution in a virus-nematode-soybean ecosystem. SCNSim was used to predict nematode suppression under a

The soybean cyst nematode (Heterodera glycines, SCN) was discovered as a significant pest of soybean in 1954 in North Carolina in the USA, and subsequently spread across a few counties in Arkansas, Missouri, Kentucky and Tennessee, as well as few other pockets in North Carolina (Winstead and Skotland, 1955). In 2014, bolstered by the increase in planting of soybean, the SCN has become a significant plant health issue all over the agrarian eastern continental United States as well as Hawaii and

Soybean (Glycine max (L.) Merr) is an important source of proteins and oil, and therefore, more research are essential to increase productivity under different conditions, including biotic stress (Pagano and Miransari, 2016). The soybean cyst nematode (SCN, Heterodera glycines) is one of the main pathogens causing yield reduction worldwide and, just in the United States it is responsible for losses of more than U$1 billion annually (Koenning and Wrather, 2010; Wu et al., 2019). The planting of

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 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

(Wrather and Koenning, 2003, 2006). 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). A survey from 2018 identified that soybean cyst and root-knot nematode

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

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

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
