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

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

Potential Host Manipulation by the Aphid Parasitoid Aphidius avenae to Enhance Cold Tolerance. [PDF]

open access: yesPLoS ONE, 2016
During parasitoid development, the immature parasitoid is confined to the host species. As a result, any potential to modify the physiology or behaviour of the host could play an important role in parasitoid fitness.

Effect of innate preferences, conditioning and adult experience on the attraction of Aphidius ervi (Hymenoptera: Braconidae) toward plant volatiles

open access: yesEuropean Journal of Entomology, 2002
The aphid parasitoid Aphidius ervi was collected and subsequently reared on Sitobion avenae on wheat or Acyrthosiphon pisum on alfalfa. Parasitoids from both origins were exposed in an olfactometer to alfalfa or wheat volatiles after plant experience ...

Genetic diversity of Sitobion avenae (Homoptera: Aphididae) populations from different geographic regions in China. [PDF]

open access: yesPLoS ONE, 2014
Sitobion avenae is a major agricultural pest of wheat in China. Using microsatellite markers, we studied the potential gene flow, genetic diversity, genetic differentiation, and genetic structure of seven S.

The effect of barley yellow dwarf virus on field populations of the cereal aphids, Sitobion avenae and Metopolophium dirhodum [PDF]

open access: yes, 1983
The numbers of cereal aphids, especially Metopolophium dirhodum in 1979, and Sitobion avenae in 1980, were significantly increased on BYDV infected wheat and oats in 1979, and wheat, barley and oats in 1980.

Comparison of field population growths of three cereal aphid species on winter wheat

open access: yesPlant Protection Science, 2003
Population growths of three aphid species colonising winter wheat stands, Metopolophium dirhodum, Rhopalosiphum padi and Sitobion avenae, were analysed by regression method.

Molecular Characterization and Functional Analysis of Wheat TtLOX Gene Involved in Aphid Resistance

open access: yesAgronomy, 2020
The English grain aphid (Sitobion avenae F.) is one of the most important and destructive pests in wheat production worldwide. Lipoxygenase (LOX) is a key rate-limiting enzyme in the bio-synthesis pathway of jasmonate and methyl jasmonate in plants and ...

Assembled genome of the Sitobion avenae symbiotic bacteria Buchnera aphidicola [PDF]

open access: yes, 2021
Assembled genome of the Sitobion avenae symbiotic bacteria Buchnera aphidicola. We extracted HiFi reads that did not map to Hemiptera contigs and assembled these using flye (with options; --pacbio-hifi, and --meta), which resulted in the assembly of a ...
