Abstract The objective of this study was to observe the response bird cherry oat aphid, Rhopalosiphum padi (Linnaeus, 1758) field rate equivalents insecticides, by using bioassays vials coated with pyrethroid, λ-cyhalothrin. results from geographically separated Irish R. colonies indicated a susceptible response, which similar finding UK showed sensitivity in species cereal aphids. Monitoring s...

Dominance hierarchy, the dominance ranking of members in a community, is determined by relative population fitness coexisting species. Climate change can shift hierarchies depending on how species respond to changing climate, but ecological mechanisms underlying such shifts remain largely unknown. Specifically, hierarchy under climate have rarely been linked eco-evolutionary responses thermal e...

Reduced forms of ascorbate (AsA) and glutathione (GSH) are among the most important non-enzymatic foliar antioxidants in maize (Zea mays L.). The survey was aimed to evaluate impact of bird cherry-oat aphid (Rhopalosiphum padi L.) or grain aphid (Sitobion avenae F.) herbivory on expression of genes related to ascorbate-glutathione (AsA-GSH) cycle in seedlings of six maize varieties (Ambrozja, N...

Crop protection is an integral part of establishing food security, by protecting the yield potential of crops. Cereal aphids cause yield losses by direct damage and transmission of viruses. Some wild relatives of wheat show resistance to aphids but the mechanisms remain unresolved. In order to elucidate the location of the partial resistance to the bird cherry-oat aphid, Rhopalosiphum padi, in ...
