“…Globodera rostochiensis and Globodera pallida originate from S. America and are known pests of other members of the Solanaceae family including tomatoes and woody nightshade [39]. These nematodes are classiied as quarantine pests in a number of countries including the U.S. and an estimated £ 50m year in proits are lost each year in the U.K. [40]. Other major plant-parasitic nematodes of potato include root-knot nematodes (Meloidogyne spp.…”

Plant-parasitic nematodes are costly burdens of crop production. Ubiquitous in nature, phytoparasitic nematodes are associated with nearly every important agricultural crop and represent a signiicant constraint on global food security. Root-knot nematodes (Meloidogyne spp.) cyst nematodes (Heterodera and Globodera spp.) and lesion nematodes (Pratylenchus spp.) rank at the top of list of the most economically and scientiically important species due to their intricate relationship with the host plants, wide host range, and the level of damage ensued by infection. Limitations on the use of chemical pesticides have brought increasing interest in studies on alternative methods of nematode control. Among these strategies of nonchemical nematode management is the identiication and implementation of host resistance. In addition, nematode genes involved in parasitism represent key targets for the development of control through gene silencing methods such as RNA interference. Recently, transcriptome proiling analyses has been used to distinguish nematode resistant and susceptible genotypes and identify the speciic molecular components and pathways triggered during the plant immune response to nematode invasion. This summary highlights the importance of plant-parasitic nematodes in agriculture and the molecular events involved in plant-nematode interactions.

“…The model was sufficient to capture the main characteristics of the data and the projections made provide a germinal risk assessment for GB that could be improved with more data. It should also be noted that a recent study concluded that increased soil temperatures associated with climate change may reduce the pest status of G. pallida in GB (Jones et al ., ). The authors found that reproductive success of G. pallida decreased with temperature from 15 to 25 °C, which was the full range of temperatures tested.…”

Potential impacts of climate change on the threat of potato cyst nematode species in Great Britain

et al. 2018

Potato cyst nematode (PCN) species have different temperature optima for various life cycle stages, therefore a risk assessment of the threat of PCN species under future climates is essential to guide adaptation strategies. Data defining the spatial coverage of potato crops in Great Britain were combined with probabilistic climate change data and a newly developed PCN life cycle model to project the future risk to potato crops from PCN. The model was based on the results of controlled environment experiments to investigate the effect of temperature on survival to female maturity using three PCN populations: Globodera pallida (Lindley) and G. rostochiensis from the James Hutton Institute PCN collection, and a field population of G. pallida (S‐Fife). It was found that projected increases in soil temperature could result in increased survival to female maturity for all three PCN populations, with greater increases expected for Scotland, followed by Wales then England. The largest projected increases in Scotland were for G. pallida, whereas G. rostochiensis showed the largest increases in Wales and England. The potential impact of several agronomic adaptation strategies on projected PCN risk were also investigated. The results from the model suggest that soil infestation levels would have to be reduced by up to 40% in order to negate projected increases in PCN risk, and that advancing the start date of the growing season or modifying planting patterns could be successful strategies to reduce future PCN risk.

“…Females were observed on the roots from week 4 onwards at Harper Adams with relatively warmer soil temperatures as found by Jones et al . (). It is probable that a second generation developed, as both juveniles and females were observed at harvests 5 (week 20) and 6 (22 weeks), although the possibility that the late females observed in the field samples may have resulted from a delayed initial hatch cannot be discounted.…”

“…In the last century, global temperatures have been increasing due to climate change and the effect of this trend on crop losses due to plant pests and diseases, including soil dwelling organisms such as PCN, is of concern (Ellenby & Smith, ; Stanton & Sartori, ; Munir et al ., ; Ebrahimi et al ., ; Jones et al ., ; Skelsey et al ., ). Recently Jones et al .…”

Population dynamics of the potato cyst nematode, Globodera pallida, in relation to temperature, potato cultivar and nematicide application

2019

View full text Add to dashboard Cite

The impact of increasing temperatures on the population dynamics of the soil‐dwelling nematode Globodera pallida, a persistent and economically important pest of potatoes, was investigated. The reproductive factor (final population⁄initial population) and length of life cycle were found to be temperature sensitive. Pot experiments performed over 4 months allowed comparison of the effect on development of G. pallida of two temperature regimes: an average temperature comparable to current field conditions (14.3 °C) and an average temperature above current field conditions (17.3 °C). A larger second generation of juveniles was observed at 17.3 °C compared to 14.3 °C. Multiplication of G. pallida at field sites in Shropshire and East Lothian (average soil temperatures of 15.5 and 14.1 °C, respectively, during potato cropping) was also examined. A quantitative PCR assay and visual examination of roots were used to monitor the dynamics of the G. pallida populations in both field sites at 4‐weekly intervals. Four cultivars, Desirée, Cara, Maris Piper and Estima, were grown with and without nematicide treatments. Nematicide treatments suppressed population increases at both sites. Females were observed on the roots of cvs Cara and Desirée at the end of the growing season in Shropshire, but not at East Lothian, and are likely to represent a second generation.
