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.

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 ...

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.

Análisis de desarrollo de población de Metopolophium dirhodum (W) en diferentes cultivares de triticale

, 1988
Looking for wheet-rye hibrids resisters to Metopolophium dirhodum (W) damage, the development of populations of this aphids was measured on selected cultivars ofthe hybrids Buck Pampero wheat and Insave F. A. rye.

Identificación molecular del endosimbionte secundario Hamiltonella defensa en el pulgón amarillo de los cereales, Metopolophium dirhodum [PDF]

, 2012
255-258This 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

Effects of temperature, feeding position and crop growth on the population dynamics of the rose grain aphid, Metopolophium dirhodum (Hemiptera: Aphididae)

, 1992
The population dynamics of Metopolophium dirhodum were studied on winter wheat seedlings at constant (10-degrees-C, 15-degrees-C, 20-degrees-C, 25-degrees-C and 30-degrees-C) and fluctuating (12(night)-22(day)-degrees-C) temperatures, and during booting ...

Competency for Yellow Dwarf Virus Transmission in the Rose‐Grain Aphid, Metopolophium dirhodum, Is Driven by Virus Species Not Vector Genotype

Plant Pathology, Volume 75, Issue 3, May–June 2026.
Barley yellow dwarf virus transmission assays show that virus diversity, not vector diversity, is the main driver of competency in the rose‐grain aphid. ABSTRACT Yellow dwarf viruses (YDVs) are a group of aphid‐vectored viruses that affect cereal crops and cause yellow dwarf disease.

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.
