Barley yellow dwarf virus in barley crops in Tunisia: prevalence and molecular characterization

open access: yesPhytopathologia Mediterranea, 2017
A field survey was conducted in Tunisia in the North-Eastern regions (Bizerte, CapBon and Zaghouan), the North-Western region (Kef) and the Central-Eastern region (Kairouan) during the 2011/2012 growing season, in order to determine the incidence and the

Pliant pathogens: Estimating viral spread when confronted with new vector, host, and environmental conditions

open access: yesEcology and Evolution, 2021
Pathogen spread rates are determined, in part, by the performance of pathogens under altered environmental conditions and their ability to persist while switching among hosts and vectors.

Temperature variability homogenized thermal responses in an ectotherm community along a European longitudinal gradient

open access: yesEcography, Volume 2026, Issue 2, February 2026.
Climate change, through rising temperatures, greater variability, and more frequent extremes, is reshaping insect phenology and thermal niches, with profound effects for pest outbreaks. Predicting these impacts requires a clear understanding of species and communities' responses across geographic gradients.

Theoretical Bases and Sources for Breeding Wheat for Combined Disease Resistance

open access: yesCzech Journal of Genetics and Plant Breeding, 2005
Achievements and prospects of wheat breeding for disease resistance in the world and in theCzech Republic are discussed. Attention was paid to possibilities of increasing resistance to rusts, powdery mildew, Fusarium head blight, leaf blotch, glume ...

Efficacy of Wheat Insecticide Seed Treatments on Bird Cherry-Oat Aphids [PDF]

open access: yes, 2018
Bird Cherry-Oat Aphids, Rhopalosiphumpadi (Linnaeus), (BCOA) are a major agricultural pest for wheat due to their ability to transferBarley Yellow Dwarf Virus (BYDV), which can stunt growth when introduced to seedlings (Wegulo, 2013). These aphids, which

The Aphids (Homoptera: Aphididae) Associated With Bell Peppers and Surrounding Vegetation in Southern Illinois [PDF]

open access: yes, 2018
Outbreaks of cucumber mosaic virus (CMV) disease, caused by an aphid- transmitted pathogen, greatly reduced yields of bell pepper in southern Illinois in the mid-1990s.

The Vulnerability of New Zealand Forage Plants to Incursions by New Pests, Pathogens and Weeds, and the Case for Greater Protection

open access: yesNew Zealand Journal of Agricultural Research, Volume 69, Issue 1, February 2026.
We outline the diversity of pests, weeds and plant pathogens absent from New Zealand that threaten forage production, examine their potential import pathways, and outline the challenges of managing them should they arrive. The number and diversity of threats and pathways indicates ongoing incursions are inevitable.

Plant functional diversity does not dilute virus infection, but community virus prevalence positively correlates with net C3 grass production

open access: yesJournal of Ecology, Volume 114, Issue 2, February 2026.
This study examines if plant functional diversity dilutes plant virus prevalence in grass hosts and evaluates how virus prevalence influences net community and host production. Functional diversity did not mitigate or amplify virus prevalence. While we found that species relationships between virus prevalence and production varied, overall, virus ...

Protein Elicitor PeaT1 Efficiently Controlled Barley Yellow Dwarf Virus in Wheat

open access: yesAgriculture, 2019
Barley yellow dwarf virus (BYDV), transmitted by the wheat aphid, generates serious wheat yellow dwarf disease and causes great losses in agriculture. Induced resistance has attracted great attention over recent years as a biological method to control ...
