Predicting aphid abundance on winter wheat using suction trap catches

Plant Protection Science, 2020
The relationship between the number of cereal aphids in flight (recorded by a national grid of suction traps in the Czech Republic) and their occurrence on winter wheat (in Prague) was established between 1999-2015.

Plant species composition alters the sign and strength of an emergent multi-predator effect by modifying predator foraging behaviour. [PDF]

PLoS ONE, 2013
The prediction of pest-control functioning by multi-predator communities is hindered by the non-additive nature of species functioning. Such non-additivity, commonly termed an emergent multi-predator effect, is known to be affected by elements of the ...

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.

Reconsidering the importance of Metopolophium dirhodum (Walker) (Hemiptera: Aphididae) as a crop pest

Agricultural 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.

Mortality of Metopolophium dirhodum (Homoptera: Aphididae) caused by strains of Erynia neoaphidis (Entomophthorales: Entomophthoraceae) from Slovakia and Greece

Plant Protection Science, 2004
The aim of the study was to test isolates of Erynia neoaphidis originating from Slovakia and Greece for infectivity to Metopolophium dirhodum, and evaluate selected strains for their infectivity at different temperatures.

Transcriptomic and proteomic signatures underlying nymphal adaptation and foam production in the forage pest Mahanarva spectabilis

Insect Molecular Biology, EarlyView.
RNA‐seq and Batelli gland proteomics of fifth‐instar Mahanarva spectabilis nymphs reveal transcripts and proteins associated with xylem feeding, foam production and environmental interaction. Functional annotation identified genes involved in osmoregulation, detoxification, chemosensation and stress responses, while proteomic analysis confirmed ...

Multi‐Omics Profiling of the Scaphoideus titanus Yeast‐Like Symbiont Guides the Bioinformatic Discovery of Related Fungal Symbioses in Insects

Environmental Microbiology, Volume 28, Issue 7, July 2026.
Genomic, proteomic and phylogenetic analyses of the obligate yeast‐like symbiont (YLS) associated with Scaphoideus titanus revealed retained metabolic flexibility and a monophyletic origin of insect‐associated YLSs within a free‐living fungal lineage. A novel computational pipeline was used to mine NCBI transcriptomic data and identified new candidate ...

Molecular identification of the secondary endosymbiont Hamiltonella defensa in the rose-grain aphid Metopolophium dirhodum Identificación molecular del endosimbionte secundario Hamiltonella defensa en el pulgón amarillo de los cereales, Metopolophium dirhodum

Revista Argentina de Microbiología, 2012
This is the first report of the association between the rose-grain aphid Metopolophium dirhodum, a potentially important cereal pest and the facultative symbiont Hamiltonella defensa. The infection with this gamma-proteobacterium was determined by PCR in

Aphid alarm pheromone (E)‐β‐farnesene: mechanisms, applications, and challenges in pest management

New Plant Protection, Volume 3, Issue 2, June 2026.
This review highlights the advances in the application of the aphid alarm pheromone (E)‐β‐farnesene (EβF) for pest management. It focuses on smart delivery systems, molecular optimization, synthetic biology, and integration with digital agriculture. Additionally, it discusses key challenges and future directions for enhancing stability, field efficacy,

Aerial migrations of the rose‐grain aphid, Metopolophium dirhodum (Wlk.), over Europe in 1979

Plant Pathology, 1980
SUMMARY Aerial migrations of Metopolophium dirhodum over Europe in 1979 measured by suction traps at a height of 12.2 m indicated that alates flew first in the south of France where the warm climate probably encouraged early population increase.
