Effect of silicon on aphid populations and wheat yield in Minas Gerais, Brazil

Semina: Ciências Agrárias, 2020
The area cultivated with wheat has been increasing in the savannahs of the state of Minas Gerais, Brazil. Aphids are usually one of the main pests of wheat in many regions of the world; however, little is known about the aphid population in this new ...

A Modelling Framework to Estimate Vector Dispersal and Disease Spread in an Important Agricultural Pathosystem

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
A model of aphid‐vectored BYDV highlights the importance of the interaction between aphid and viral genetic and species diversity on the risk presented by crop disease. The modelling framework offers a tool to explore vector–virus–host interactions and both conventional and natural controls in a spatial context.

Tritrophic interactions between cereals, aphids and parasitoids: Discrimination of different plant-host complexes by Aphidius rhopalosiphi (Hymenoptera: Aphidiidae)

European Journal of Entomology, 2000
The tritrophic interactions between two different plant-host complexes, Avena sativa-Sitobion avenae, Triticum aestivum-S. avenae and the aphid parasitoid Aphidius rhopalosiphi were studied with respect to odour learning and recognition by the parasitoid.

Climate Change Can Generate Enemy‐Free Space for Crop‐Feeding Herbivores

Global Change Biology, Volume 32, Issue 3, March 2026.
Magnitude and direction of change in parasitoid pressure for 14 agricultural pests subject to climate‐driven distributional shifts. Pests are organized per increasing parasitoid pressure under current climatic conditions (X axis). Bubble size is reflective of the (absolute) area affected by a given pest under a given scenario.

The effect of barley yellow dwarf virus on honeydew production by the cereal aphids Sitobion avenae and Metopolophium dirhodum

, 1982
Individual S. avenae and M. dirhodum excreted significantly fewer droplets of honeydew on plants infected with BYDV than on healthy plants. S. avenae excreted less honeydew on the ears than on the leaves of wheat. M. dirhodum excreted less than S. avenae

Temperature variability homogenized thermal responses in an ectotherm community along a European longitudinal gradient

Ecography, Volume 2026, Issue 2, February 2026.
Climate change, through rising temperatures, greater variability, and more frequent extremes, is reshaping insect phenology and thermal niches, with profound effects for pest outbreaks. Predicting these impacts requires a clear understanding of species and communities' responses across geographic gradients.

Dual role of benzoxazinoids in plant response to combined drought stress and aphid feeding

Plant Biology, Volume 28, Issue 1, Page 45-57, January 2026.
Benzoxazinoids enhance wheat's defence against aphids and drought stress by triggering callose accumulation, and MYB transcription factors regulate wheat stress response. Abstract Plants produce specialized metabolites like benzoxazinoids (BXDs) to survive adverse environmental conditions and deter herbivory, while insects have evolved mechanisms to ...

Viral Systemic Movement Is Enhanced by Alteration of a Structural Phloem Protein by the Insect Vector

Advanced Science, Volume 12, Issue 45, December 4, 2025.
Aphids release salivary protein GLD into plants, which induces ROS in the phloem. This leads to the intermolecular disulfide bonds formation among SEO proteins, promoting their transition from the dispersed state to the aggregated state. SEO can interact with CMV CP.
