Prevalent Pest Management Strategies for Grain Aphids: Opportunities and Challenges [PDF]

Frontiers in Plant Science, 2022
Cereal plants in natural ecological systems are often either sequentially or simultaneously attacked by different species of aphids, which significantly decreases the quality and quantity of harvested grain.

Impacts of Constitutive and Induced Benzoxazinoids Levels on Wheat Resistance to the Grain Aphid (Sitobion avenae) [PDF]

Metabolites, 2021
Benzoxazinoids are important secondary metabolites in gramineae plants and have inhibitory and toxic effects against a wide range of herbivore pests.

Selenium nanoparticles enhance innate immunity in aphid-stressed oat plants by modulating photosynthetic pigments, sugar, nitrogen and fatty acid metabolism, and antioxidant defense [PDF]

BMC Plant Biology
Oat (Avena sativa L.) is an important cereal crop threatened by insect stress from the grain aphid (Sitobion avenae), which reduces photosynthetic efficiency, sugars, amino acids, and nitrogen metabolism, ultimately impairing plant growth.

Host-Induced Gene Silencing of SmDSR32 Enhances Wheat Defense Against Sitobion miscanthi [PDF]

Current Issues in Molecular Biology
The grain aphid, Sitobion miscanthi, poses a serious threat to cereal crops worldwide, leading to considerable yield losses and demanding annual insecticide applications during the grain-filling stage.

A chromosome-level draft genome of the grain aphid Sitobion miscanthi. [PDF]

Gigascience, 2019
Abstract Background Sitobion miscanthi is an ideal model for studying host plant specificity, parthenogenesis-based phenotypic plasticity, and interactions between insects and other species of various trophic levels, such as viruses, bacteria, plants, and natural enemies.

Resistance of Wheat Accessions to the English Grain Aphid Sitobion avenae. [PDF]

PLoS One, 2016
The English grain aphid, Sitobion avenae, is a major pest species of wheat crops; however, certain varieties may have stronger resistance to infestation than others. Here, we investigated 3 classical resistance mechanisms (antixenosis, antibiosis, and tolerance) by 14 wheat varieties/lines to S. avenae under laboratory and field conditions.

Transcriptome analysis of the salivary glands of the grain aphid, Sitobion avenae. [PDF]

Sci Rep, 2017
AbstractAphid saliva plays important roles in aphid-host interactions, such as assisting aphid digestion, detoxification, activating or suppressing plant defenses. The grain aphid, Sitobion avenae, is one of the most devastating pests of cereals worldwide. In this study, we performed the transcriptome analysis of salivary glands of S. avenae.

Discovery of English Grain Aphid (Hemiptera: Aphididae) Biotypes in China [PDF]

Journal of Economic Entomology, 2011
The English grain aphid, Sitobion avenae (F.) (Hemiptera: Aphididae), is an important pest insect of wheat, Triticum aestivum (L.), in China. Grain aphid biotypes are necessary to breed aphid-resistant wheat varieties; however, none have currently been identified.

Effects of insecticide use, host plant resistance, and nitrogen fertilization on the density of Melanaphis sorghi and the production of grain sorghum [PDF]

Scientific Reports
Melanaphis sorghi is a serious economically important pest of sorghum, Sorghum bicolor (L.), across the southern USA. Therefore, developing and refining integrated strategies that provide effective control is key to the management of this pest.

Effects of Confinement and Wheat Variety on the Performance of Two Aphid Species [PDF]

Insects
Bird cherry-oat aphid (Rhopalosiphum padi L.; Hemiptera: Aphididae) and English grain aphid (Sitobion avenae Fabricius; Hemiptera: Aphididae) are economically important cereal crop pests and effective vectors of barley yellow dwarf virus (BYDV).
