Variation in the abundance of Rhopalosiphum padi in Finland [PDF]

open access: yes, 2009
The bird cherry-oat aphid, Rhopalosiphum padi (L.), is the major aphid pest in spring cereals in Finland. It is also the vector of Barley yellow dwarf virus (BYDV) which is the most serious virus disease of cereals. The Finnish forecast of R.

Why we age

open access: yesBiological Reviews, EarlyView.
ABSTRACT Three categories of explanations exist for why we age: mechanistic theories, which omit reference to evolutionary forces; weakening force of selection theories, which posit that barriers exist that prevent evolutionary forces from optimising fitness in ageing; and optimisation theories, which posit that evolutionary forces actually select for ...

Does This Look Infected? Hidden Host Plant Infection by the Pathogen Botrytis cinerea Alters Interactions between Plants, Aphids and Their Natural Enemies in the Field

open access: yesInsects
Few studies have considered whether hidden (asymptomatic) plant pathogen infection alters ecological interactions at the higher trophic levels, even though such infection still affects plant physiology. We explored this question in two field experiments,

UHPLC‐MSE Insights Into Extrusion‐Driven Changes in Wheat Phenolics and Their Bioaccessibility

open access: yesCereal Chemistry, EarlyView.
ABSTRACT Background and Objectives This study evaluated the impact of thermoplastic extrusion (wheat snack, WS) and cold extrusion followed by cooking (wheat pasta, WP) on phenolic compounds (PC) in two Brazilian wheat genotypes, commercially classified by gluten strength (ORS Agile, strong; ORS Vintecinco, weak).

Influence of Weather Conditions and the Aphid Population on the Potato Virus Y Infection of Tobacco in the Field

open access: yesAgronomy
Potato virus Y (PVY) is a major tobacco (Nicotiana tabacum L.) pathogen that causes severe crop losses. We studied the influence of meteorological factors and a population of twelve aphid species on the development of PVY in field-grown tobacco from 1996

Effect of temperature on fecundity and development of the Giant Willow Aphid, Tuberolachnus salignus (Sternorrhyncha: Aphididae)

open access: yesEuropean Journal of Entomology, 2001
This study investigates the thermal requirements, nymphal development rates and the fecundity of both alate and apterous adults of the giant willow aphid, Tuberolachnus salignus (Gmelin) at several temperatures.

Dietary‐Driven Gene Expansion

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Gene duplication has been shown to drive molecular evolution, with dietary pressures expanding detoxification genes across species. In humans, CYP2D6 gene duplications enhance alkaloid and drug metabolism, reflecting ancient dietary adaptations. Similarly, tobacco‐feeding aphids amplify CYP6CY3 for nicotine and insecticide resistance, and as recently ...
