Ant–aphid mutualism: the influence of Tapinoma ibericum (Hymenoptera: Formicidae) on Aphis gossypii (Hemiptera: Aphidae) control by commercial and spontaneous natural enemies

open access: yesInsect Science, EarlyView.
The mutualism between Tapinoma ibericum ants and Aphis gossypii disrupts the biological control exerted by Aphidius colemani in greenhouse peppers. Ant exclusion increased parasitism and the presence of most natural enemies, although Aphidoletes aphidimyza was more abundant with ants.

Handling mean–variance scaling in intraspecific trait variability and implications for trait–environment analyses

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Trait‐based ecology increasingly relies on measures of intraspecific trait variability to estimate how trait diversity within species varies across species and environmental gradients. Yet variance and related metrics are often interpreted without considering their intrinsic dependence on the mean, as described by the empirical Taylor's power ...

A nanobiotechnological approach to control non‐persistent aphid‐transmitted plant viruses, based on functionalized virus‐like particles

open access: yesAnnals of Applied Biology, Volume 189, Issue 3, November 2026.
A potyvirus‐derived virus‐like nanoparticle (VLP) interferes in the transmission by aphids of the non‐circulative plant viruses turnip mosaic virus (TuMV, Potyvirus), zucchini yellow mosaic virus (ZYMV, Potyvirus), and cucumber mosaic virus (CMV, Cucumovirus) is also observed. The construct, that consisted of a fusion between a modified TuMV HC‐Pro and

Rhizobial Symbiosis Enhances Salinity Tolerance in Legumes Through Coordinated Physiological and Molecular Responses: Evidence From Common Vetch and Pea

open access: yesPlant, Cell &Environment, Volume 49, Issue 11, Page 8912-8931, November 2026.
ABSTRACT Soil salinisation severely constrains crop production. Legumes rely on rhizobial symbiosis for sustainable nitrogen acquisition. Although salinity is known to impair nodulation and nitrogen fixation, how symbiosis influences plant tolerance to salt stress remains unclear.
