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 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

Soybean meal is the main vegetable protein source in animal feed. Soybean meal contains several anti-nutritional factors, which directly affect digestion and absorption of soy protein, thereby reducing growth performance and value in animals. Fermented soybean meal is rich in probiotics and functional metabolites, which facilitates soybean protein digestion, absorption and utilization in piglets. However, the mixed solid-state fermentation (SSF) conditions of soybean meal remain to be optimized

Information about the effects of glyphosate on nematodes is limited and contradictory, while none existing for South African agricultural fields. The abundance and identity of non-parasitic nematodes in the rhizospheres of commercial glyphosate-tolerant and conventional (non-glyphosate-tolerant), soybean cultivars from cultivated fields, and adjacent natural vegetation (reference system) were obtained for two growing seasons. The impact of glyphosate was also investigated on non-parasitic

The soil is dominated by ash-calcium soil. The soybean rhizosphere soil samples, numbered as S, were collected on June 24, 2016, when after more than half of the cotyledons were breaking out, and also the soil samples, numbered as M, were collected on September 30, 2016. At this time, the leaves and beans were dehydrated

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

In the United States, corn and soybean are among the most important crops, comprising 36.0 and 36.2 million hectares, respectively, in 2018, which was 55.5% of total area planted to principal crops (NASS-USDA, 2018). Since these crops cover such a large area, identifying management practices in corn and soybean production that promote sustainability (productivity over time while conserving natural resources) is an important goal. Nematodes play an important role in sustainability because

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

Spiral nematodes (Helicotylenchus spp.) are common plant-parasitic nematodes in fields of many crops. In June 2015, two soil samples were collected from a soybean field in Richland County, ND. Nematodes were extracted from soil using the sugar centrifugal flotation method ( Jenkins, 1964). Plant-parasitic nematodes were identified to genus based on morphological features and counted. Both samples contained spiral nematodes from 1,500 to 3,300 per kilogram of soil. In June and August

The southern root-knot nematode, Meloidogyne incognita (Kofoid and White) Chitwood race 3, is an important yield-limiting pest of cotton (Gossypium hirsutum L.) and soybean (Glycine max (L.) Merr.) in the southern USA (Thomas and Kirkpatrick, 2001; Koenning, 2015). Furthermore, it is the most prevalent species of root-knot nematode in Arkansas (Ye et al., 2019).

Edamame, also known as vegetable soybean, is a high-fiber, low-sugar snack that has gained popularity in the USA in recent years. Not only does edamame have a high protein content but it also contains all the essential amino acids the human body requires for proper nutrition (Dixit et al., 2011). Compared to traditional soybeans grown for oil or grain production that are harvested at reproductive maturity, edamame is a shorter-season crop that is harvested before the seed is mature. Edamame is

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

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

Native and invasive stink bugs (Hemiptera: Pentatomidae) and the closely related invasive Megacopta cribraria (Hemiptera: Plataspidae) are agricultural pests in the southeastern United States. Natural enemies, from various phyla, parasitize these pests and contribute to population regulation. We specifically investigated Nematoda infections in pentatomid and plataspid pests in one soybean field in South Carolina in 2015. Nematodes were identified through molecular and morphological
