Elevated UV‐B alters anti‐herbivore plant defence allocation, while silicon supplementation maintains resistance

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The impacts of elevated surface ultraviolet‐B (UV‐B) on ecological processes, such as anti‐herbivore defence in plants, remain poorly understood. Many cereal crops depend on accumulating silicon (Si) in their tissues to resist insect herbivory.

Ecohydrological characteristics of biocrusts explain divergent responses of biocrusts and grasses to rainfall reduction

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Drylands are mainly structured by both vascular plants and biological soil crusts (biocrusts), the latter often regarded as a self‐organizing component of these ecosystems.

Complex multitrophic species interactions and fitness costs: Intricate consequences of jasmonate and salicylate induced plant defences

open access: yesJournal of Animal Ecology, EarlyView.
This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

Offspring performance does not explain oviposition preference in the leafminer Stigmella sorbi (Lepidoptera: Nepticulidae): a tri‐trophic perspective

open access: yesInsect Science, EarlyView.
We studied oviposition site selection in a leaf‐mining moth (Stigmella sorbi) on rowan trees (Sorbus aucuparia) in northwestern Russia, assessing larval performance across different shoot types, leaf positions, and leaflets. Larval survival was highest on long vegetative shoots, yet females showed no preference for these optimal sites.

Multi‐Omics Analysis Reveals Coordinated Adaptations in Genes, Metabolism, and Gut Microbiota Underpinning Herbivory in Lordiphosa Flies

open access: yesIntegrative Zoology, EarlyView.
Multi‐omics analysis reveals that herbivorous adaptation in Lordiphosa flies arises from coordinated interactions across the genome, transcriptome, and gut microbiota: genomic expansions of detoxification (e.g., cytochrome P450s) and carbohydrate metabolism gene families, transcriptomic upregulation of energy pathways like lipid oxidation and ...

Neonicotinoid seed treatments do not consistently reduce insect feeding damage nor increase yields in Maryland soy

open access: yesAgricultural and Forest Entomology, EarlyView.
We compared soybean plants from untreated and treated seeds across 4 sites and 3 years in Maryland. Neonicotinoid seed treatments (NST) provided little reduction in insect stippling damage and no reduction in chewing damage. NST did not result in increased plant biomass or bean yield. Abstract The use of neonicotinoid insecticides in seed treatments in

Evidence for positive population‐level responses but not individual performance of sycamore aphids under elevated CO2

open access: yesAgricultural and Forest Entomology, EarlyView.
The abundance and density of three common sycamore aphids increased under elevated CO2, although this was only statistically significant for Drepanosiphum platanoidis. The number of nymphs produced by individual D. platanoidis alates isolated in clip cages was not significantly affected, suggesting that population level response was not driven by ...

Reconsidering the importance of Metopolophium dirhodum (Walker) (Hemiptera: Aphididae) as a crop pest

open access: yesAgricultural and Forest Entomology, EarlyView.
Four‐year field monitoring and laboratory studies revealed M. dirhodum occurs regularly in barley with high reproductive potential and extended adult longevity. Populations peaked during vulnerable crop stages, creating optimal conditions for BYDV transmission during critical infection windows. M.

Attractiveness of Melon Genotypes to Whitefly (Bemisia tabaci) Mediated by Foliar Morphological and Biochemical Traits

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
This study identifies melon genotypes resistant to Bemisia tabaci by integrating morphological and biochemical leaf traits. Using free‐choice and no‐choice assays, we demonstrate that resistance is primarily mediated by antixenosis. Genotypes CNPH 11‐1071‐43, CNPH 06‐1047‐343, CNPH 13‐1076, and BG MEL 16 significantly reduced whitefly settling and ...
