We studied the effect of the cereal aphid (the bird cherry-oat aphid Rhopalosiphum padi L. and grain aphid Sitobion avenae F.) infestations on the oxidative damages of protein in the maize (Zea mays L., cultivar Touran) seedlings.

Impact of water-deficit stress on tritrophic interactions in a wheat-aphid-parasitoid system. [PDF]
Increasing temperature and CO2 concentrations can alter tritrophic interactions in ecosystems, but the impact of increasingly severe drought on such interactions is not well understood.

In-field prevalence of resistant grain aphid Sitobion avenae (Fabricius)
A concerning development for Irish agriculture is the detection of partial resistance in the main aphid pest (Sitobion avenae) of cereal crops to the most widely used pyrethroid insecticide compound.

Identification and Expression Analysis of Candidate Odorant-Binding Protein and Chemosensory Protein Genes by Antennal Transcriptome of Sitobion avenae. [PDF]
Odorant-binding proteins (OBPs) and chemosensory proteins (CSPs) of aphids are thought to be responsible for the initial molecular interactions during olfaction that mediate detection of chemical signals.

The grain aphid (Sitobion avenae) is a major pest of winter wheat, causing significant yield losses through direct feeding and as a vector of barley yellow dwarf virus (BYDV). Populations can increase rapidly under moderate temperatures and low rainfall,

The English grain aphid Sitobion avenae is a major pest of cereals in Europe, with control hindered by pyrethroid resistance in a single clonal lineage (SA3) due to a mutation in the voltage-gated sodium channel gene (knockdown resistance or kdr).

Genetic basis and selection for life-history trait plasticity on alternative host plants for the cereal aphid Sitobion avenae. [PDF]
Sitobion avenae (F.) can survive on various plants in the Poaceae, which may select for highly plastic genotypes. But phenotypic plasticity was often thought to be non-genetic, and of little evolutionary significance historically, and many problems ...

The study has identified mutations in the voltage gated sodium channel of the English grain aphid (Sitobion avenae) at M918 and L932, which have not been previously reported in this species. Abstract BACKGROUND The grain aphid, Sitobion avenae Fabricius (Hemiptera: Aphididae), is a vector of yellow dwarf viruses and an important pest of cereals.

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders
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.
