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.

Metabarcoding of Pollen Carried by Syrphids Reveals Novel Plant–Pollinator Interactions in a Protected Natural Area and Agricultural Sites

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.

Estimating Economic Thresholds and Economic Injury Levels for Schizaphis graminum (Rond.) and Sitobion avenae Fab. Infesting Wheat Plants in Najaf Government, Iraq [PDF]

open access: yesJournal of Plant Protection and Pathology
Wheat (Triticum aestivum L.) is a vital cereal crop in Iraq and worldwide, but its productivity is threatened by cereal aphids, particularly Schizaphis graminum and Sitobion avenae.

Relationship between water soluble carbohydrate content, aphid endosymbionts and clonal performance of Sitobion avenae on cocksfoot cultivars. [PDF]

open access: yesPLoS ONE, 2013
Aphids feed on plant phloem sap, rich in sugars but poor in essential amino acids. However, sugars cause osmotic regulation problems for aphids, which they overcome by hydrolysing the sugars in their gut and polymerising the hydrolysis products into ...

Revealing Functional Traits of Insect Pest Suppressive Rhizobacterial Strains Through Comparative Genomics

open access: yesEnvironmental Microbiology, Volume 28, Issue 9, September 2026.
Inoculation of select rhizobacterial strains to enhance crop health is a growing field in sustainable agriculture. This study conducts a comparative genomic analysis of five plant‐beneficial rhizobacterial strains (Acidovorax radicis N35, Bacillus subtilis B171, Bacillus velezensis FZB42 Rhizobium radiobacter F4 and Pseudomonas simiae WCS417r ...

Ecological impact of a secondary bacterial symbiont on the clones of Sitobion avenae (Fabricius) (Hemiptera: Aphididae). [PDF]

open access: yesSci Rep, 2017
Many insects harbor heritable endosymbionts, whether obligatory or facultative, and the role of facultative endosymbionts in shaping the phenotype of these species has become increasingly important.

Dispersal responses of cereal aphids to wheat cultivar and planting configuration

open access: yesAnnals of Applied Biology, Volume 189, Issue 2, September 2026.
Aphid dispersal responses were species‐specific, cultivar‐dependent and altered by virus infection status. Rhopalosiphum padi preferentially colonised Maris Huntsman, but the presence of Wolverine plants disrupted arrestment and produced spatially uniform dispersal resembling that on Wolverine monocultures.

cis -Jasmone treatment induces resistance in wheat plants against the grain aphid, Sitobion avenae (Fabricius) (Homoptera: Aphididae)

open access: yes, 2003
cis-Jasmone is a plant volatile known to have roles as an insect semiochemical and in inducing plant defence. It was evaluated in laboratory and field trials for control of cereal aphids. In an olfactometer bioassay cis-jasmone was repellent to alatae of
