Identification and Expression Analysis of Candidate Odorant-Binding Protein and Chemosensory Protein Genes by Antennal Transcriptome of Sitobion avenae. [PDF]

PLoS ONE, 2016
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 major carotenoid pigments of the grain aphid, Sitobion avenae (F.) (Hemiptera: Aphididae)

, 1999
The economically important grain aphid, Sitobion avenae (F.) shows colour polymorphism with brown and green forms predominating. Colour is determined both genetically and in response to environmental factors, including nutrition.

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

, 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

Monitoring Sitobion avenae Infestations in Winter Wheat Using UAV-Obtained RGB Images and Deep Learning

Agriculture
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,

Genetic basis and selection for life-history trait plasticity on alternative host plants for the cereal aphid Sitobion avenae. [PDF]

PLoS ONE, 2014
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 ...

Entomophthora infecting the cereal aphids Metapolophium dirhodum and Sitobion avenae

Journal of Invertebrate Pathology, 1971
Abstract Entomophthora aphidis, E. planchoniana, and E. thaxteriana killed many Metapalophium dirhodum and Sitobion avenae in barley during 1970. E. planchoniana first infected M. dirhodum late in June, after rain ended a long dry period, but few aphids were infected until after July 7, when heavy rain killed 65–80% of aphids. E. planchoniana was 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.

Estimating Predation of the Grain Aphid Sitobion avenae by Polyphagous Predators

The Journal of Applied Ecology, 1994
1. The numbers of dead and live aphids falling to the ground in a cereal crop were estimated. The estimates showed that more live aphids fall to the ground than dead ones. 2. The availability of live aphids to predators which forage on the ground was low because aphids quickly returned to the crop canopy.

Differentially expressed microRNAs under imidacloprid exposure and identification in Sitobion avenae [PDF]

, 2019
Abstract BACKGROUD MicroRNAs (miRNAs) are short single-stranded non-coding RNAs that regulate the expression of target genes, especially regulation or metabolism of endogenous or xenobiotic compounds. RESULTS The de novo assembly of the transcriptomes was obtained through Illumina short-read sequencing technology in Sitobion avenae.

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

Entomologia 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.
