DNA barcoding evidence for the North American presence of alfalfa cyst nematode, Heterodera medicaginis

Alfalfa cyst nematode, Heterodera medicaginis (Kirjanova & Krall, 1971) was originally described from the USSR in 1971 and redescribed by Gerber and Maas (1982). The redescription added information missing in the original description regarding juvenile and male stages (Gerber and Maas, 1982). Host testing was conducted for the redescription that included 20 plant species from 7 plant families. These tests included Glycine max, Medicago lupulina, M. sativa, Phaseolus vulgaris, Pisum sativum

First Report of the Fig Cyst Nematode, Heterodera fici Kirjanova, on Fig Tree, Ficus carica, in Ontario, Canada

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

An Agent-Based Metapopulation Model Simulating Virus-Based Biocontrol of Heterodera Glycines

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

Active and inactive forms of biotin synthase occur in Heterodera glycines

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

Field and greenhouse evaluations of soil suppressiveness to Heterodera glycines in the Midwest corn-soybean production systems

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

Reproduction and life history traits of a resistance breaking Globodera pallida population

The potato cyst nematode (PCN) Globodera pallida (Stone, 1972) is a potato pest of economic importance worldwide. Plant resistance is the most efficient way to reduce crop damage and reproduction of this nematode. In contrast to Globodera rostochiensis (Wollenweber, 1923) which is effectively controlled using resistant potato cultivars, there is a lack of cultivars with stable resistance to G. pallida pathotypes. Nevertheless, using plant resistance in an integrated pest management system
