Ecological Entomology, EarlyView.Different BYDV‐PAV isolates exert contrasting effects on aphid fitness, including reproduction and winged production. Different BYDV‐PAV isolates have contrasting effects on aphid dispersal patterns. Aphid feeding behaviour is modulated by the presence of endosymbionts and plant viruses.

Felons’ chattels and English living standards in the later fourteenth and fifteenth centuries
The Economic History Review, EarlyView.Abstract The later fourteenth and fifteenth centuries have long occupied an intriguing and contested place in discussions of England's long‐run economic development. One key issue around which debate has coalesced is the living standards of the population as a whole and of different groups within it. We contribute to this debate by bringing forward new

The Economic History Review, EarlyView.Abstract We develop new datasets of monthly grain prices in 14 urban markets and of the storage and marketing of grain by 5 rural estates located in western Germany between the late seventeenth century and c. 1860. We explore whether observed patterns of monthly prices, sales, and storage of grain are consistent with the rational competitive storage ...

The commercialization of labour markets: Evidence from wage inequality in the Middle Ages
The Economic History Review, EarlyView.Abstract This paper moves beyond the focus on ‘average’ wage trends in pre‐industrial economies by examining the broad diversity of pay rates and forms of remuneration across occupations and regions in medieval England. We find that whilst some workers enjoyed substantial growth in wage rates after the Black Death, there was a large group who ...

Effect of Endophytic Fungi on Thrips tabaci Development and Population Dynamics
Journal of Applied Entomology, EarlyView.ABSTRACT Endophytic fungi are promising biocontrol agents because they colonise healthy plant tissues asymptomatically while inducing systemic resistance that negatively affects herbivorous insects. We investigated whether treatments with the endophytes Trichoderma harzianum and Beauveria bassiana in two onion cultivars (Allium cepa L.; Sturon and Red ...

Spring barley genotypes Lav and Branko
, 2001 In 2000, the Federal Variety Commission registered two new cultivars of spring barley Lav and Branko. Botanically, both are classified as two-rowed spring barley (Hordeum sativum, ssp. distichum var. nutans). The cultivar Lav was developed by crossing the cultivars Novosadski 294, Alva, and Novosadski 313, while the cultivar Branko is a result of a ...

Engineering the bacterial nutrition strategy to control plant diseases
Journal of Integrative Plant Biology, EarlyView.This commentary on Wang et al. (2025) and Phan et al. (2025) highlights previously undiscovered Xanthomonas pathways for nutrition acquisition, explains how Xanthomonas bacteria hijack host molecular machinery through their effector proteins, and discusses how these studies can be used to develop new disease resistance mechanisms.
