Host plant richness and abundance drive populations of a super‐generalist xylem‐feeding insect
Philaenus spumarius abundance was assessed across 93 sites and four habitat types (olive groves, vineyards, meadows, and field margins) within eight heterogeneous agricultural landscapes over the year. In spring, nymph abundance was positively associated with herbaceous plant species richness and vegetation cover, highlighting that even super ...

In a given number of samples, grassland sward islets contain more species of arthropods than the surrounding sward. When corrected for abundance, there is no difference in species richness, suggesting that the effect of islets might purely be to concentrate arthropods. The community structure differences indicated by non‐metric multidimensional scaling

Hairy Roadblock: Stem Trichomes Impede Herbivore Movement in a Species and Instar‐Dependent Manner
ABSTRACT Plants have evolved to deploy a vast set of defence mechanisms against insect herbivores, including physical barriers like leaf trichomes with pre and post ingestive effects. Yet, the role of stem trichomes in plant‐herbivore interactions, particularly mobility dynamics, is poorly understood.

ABSTRACT Within the subfamily Heliothinae, the genus Helicoverpa comprises several highly destructive agricultural pests, including H. armigera, H. assulta, H. punctigera and H. zea. These species cause significant global crop losses due to their wide host range, long‐distance migratory behaviour, and potential for interspecific hybridization.

BAHD acyltransferases drive metabolic diversification in plants by coupling conserved catalytic scaffolds with regulatory flexibility, enabling stress adaptation and ecological specialisation. ABSTRACT BAHD acyltransferases constitute one of the most versatile enzyme superfamilies in plants, catalysing the acylation of alcohols, amines, polyamines, and

ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.
