Integrative biology of injury in animals
ABSTRACT Mechanical injury is a prevalent challenge in the lives of animals with myriad potential consequences for organisms, including reduced fitness and death. Research on animal injury has focused on many aspects, including the frequency and severity of wounding in wild populations, the short‐ and long‐term consequences of injury at different ...

Diffusion of constructed resources and specialism promote facilitation in spatial systems
Sessile organisms, such as plants, contend with locally limiting nutrients and neighbours. By consuming nutrients or increasing local concentration by niche construction, they alter the conditions of growth in their local environment. Diffusion of resources alters the interaction sign between two neighbours usually thought to compete for resources.

Characterisation of aphid antixenosis in aphid‐resistant ancestor wheat, Triticum monococcum
A blend of 21 volatile organic compounds (VOCs) released from Sitobion avenae‐infested Triticum monococcum accessions MDR045 and MDR049 was identified and shown to induce antixenosis towards alate S. avenae. Abstract BACKGROUND Due to the increasing presence of insecticide resistance across cereal aphid populations, new aphid management strategies ...

How urban proximity shapes agricultural pest dynamics: a review
This review explores how proximity to human settlements affects agricultural pest and pathogen dynamics, highlighting the roles of microclimatic conditions, biological aspects, and management effects. It underscores the need for integrated pest management strategies to address these complex interactions and enhance sustainable agriculture.

Soils contain biotic and abiotic legacies of previous conditions that may influence plant biomass production and associated aboveground biodiversity. We used an outdoor mesocosm experiment to investigate the soil legacy effects of plants, extreme drought, and their interactions on plant biomass production, and on the abundance of aphids and pollinators.

Altruistic defence behaviours in aphids [PDF]
Altruistic anti-predatory behaviours pose an evolutionary problem because they are costly to the actor and beneficial to the recipients. Altruistic behaviours can evolve through indirect fitness benefits when directed toward kin. The altruistic nature of anti-predatory behaviours is often difficult to establish because the actor can obtain direct ...

Silencing Prosbeta‐5 and Prosbeta‐1 resulted in high mortality in Tetranychus urticae, identifying them as potential target genes for double‐stranded RNA‐based biopesticides using spray‐induced gene silencing (SIGS). Abstract BACKGROUND Because of the excessive use of synthetic chemicals, the two‐spotted spider mite, Tetranychus urticae Koch, a highly ...

La biosynthèse des isoprénoïdes chez les pucerons : une cible potentielle de nouveaux bio-insecticides ? [PDF]
Isoprenoid metabolism in aphids: a new target for bio-insecticides development? Currently, the control of aphids is largely dependent on the use of broad-spectrum chemical insecticides.

The addition of 10 μg cm−2 of Cry1Ac to the surface of GS‐omega/kappa‐Hxtx‐Hv1a (ω/κ‐Hv1a) incorporated diet can significantly increase the mortality of Cry‐resistant Helicoverpa zea compared to diets without the Cry1Ac toxin. Abstract BACKGROUND Helicoverpa zea and Spodoptera frugiperda are destructive insect pests of cotton and corn.
