Iflaviruses in arthropods: when small is mighty

open access: yesInsect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

US Farm Bill in 2025: Ad Hoc Assistance becomes an Expanded Multi‐Year Safety Net Loi agricole américaine de 2025 : l'aide ponctuelle devient un filet de sécurité pluriannuel élargi US Farm Bill in 2025: Ad‐hoc‐Beihilfen werden zu einem erweiterten mehrjährigen Sicherheitsnetz

open access: yesEuroChoices, EarlyView.
Summary The 2025 US farm bill converts ad hoc farm assistance since 2018 into a projected US$ 62 billion farm safety net expansion within multi‐year legislation. Usually stand‐alone with strong bipartisan support, the 2025 edition is largely provisions in a far‐reaching, partisan budget law. The farm safety net is expanded by cutting food assistance to

Effect of residual nitrogen and fertilizer nitrogen on sugar beet production in Finland

open access: yesAgricultural and Food Science, 1974
Preliminary determinations for NO3- and NH4-N in topsoil from nitrogen field experiments are discussed. The amounts of residual nitrogen as well as the dates and depth for sampling are considerd in order to investigate the need of fertilizer-N for ...

PRICE VARIABILITY AND FINANCIAL RISK FOR SUGAR BEET GROWERS

open access: yes
This paper develops a portfolio framework to characterize and analyze the impact of price risk faced by sugar beet growers in the Red River Valley and derives implications for capital markets. Other sources of risk incorporated in the analysis are yields

Ortolan buntings (Emberiza hortulana) consistently select breeding territories with structurally diverse crops on well‐drained soils

open access: yesConservation Science and Practice, EarlyView.
This study investigated consistency in habitat selection over a 12‐year period in a breeding population of Ortolan Bunting in Uelzen, Lower Saxony (Germany). We demonstrate strong interannual variation in crop type preferences and avoidance and breeding territories were strongly associated with well‐drained soils with low soil fertility.

Global welfare effects of transgenic sugar beet

open access: yes
Although the EU is still in a quasi moratorium stage concerning GM crops, doors for GM crops in the sugar industry seem to open. Herbicide tolerant sugar beet could mean a boost for the sugar beet sector.

Comparing Methods for Measuring Predation: Toward a Quantitative–Informative Indicator of Natural Pest Control

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Predation methods vary widely in their ability to quantify biological control. Estimating predation rates (the number of prey killed per predator per time unit) is crucial. Combining predation rates with predator abundance yields real‐time field estimates of pests consumed.

Quantifying Species‐ and Community‐Level Predation by Carabids on Pests and Beneficials in Wheat and Beet Fields

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Using a model that translates qualitative prey detection data (presence/absence in predator gut contents) into quantitative predation rates, we estimate species‐specific diets of nine carabid species across three cropping contexts (wheat, sugar beet, and fodder beet) for five prey types.
