Innate behaviours shape generalist herbivore host choice and feeding patterns independent of plant defences

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant–herbivore interactions are typically examined through plant defence and herbivore performance, yet individual herbivore behavioural mechanisms underlying these interactions are rarely considered alongside plant traits.

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

Journal 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

Insect 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.

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Intra- and interspecific diversity in a tropical plant clade alter herbivory and ecosystem resilience

eLife
Declines in biodiversity generated by anthropogenic stressors at both species and population levels can alter emergent processes instrumental to ecosystem function and resilience.

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

Integrative 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 ...

Herbivory resistance and leaf nutritional quality of hybrid poplar (Populus deltoides × petrowskyana) × petrowskyana exposed to salinity and Orgyia leucostigma [PDF]

When plants encounter salinity and herbivory simultaneously, these stress factors may interact synergistically or antagonistically due, among other things, to crosstalk between signaling pathways involved in the response to each factor.

Leaf, tree and soil properties in a Eucalyptus saligna forest exhibiting canopy decline [PDF]

, 2013
The extent of eucalypt decline in moist coastal forests of south-eastern Australia is increasing with resultant losses in biodiversity and productivity. This survey aimed to identify factors associated with the decline of Eucalyptus saligna (Sydney Blue ...

Tree Squirrels Selectively Disperse High‐Quality Acorns Away From Tree Trunks

Integrative Zoology, EarlyView.
Acorn quality and squirrel feeding behavior significantly structured spatial dispersal patterns of two Californian oak species. Non‐infested acorns were preferentially selected for embryo excision and dispersed farther than infested ones. Acorns were fully consumed near tree trunks, signaling rapid feeding in safe refuges, whereas non‐eaten, partially ...

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

Agricultural 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
