Population growth modeling of rose‌-‌grain aphid, Metopolophium dirhodum (Hemiptera: Aphididae) on wheat in field condition [PDF]

open access: yesنامه انجمن حشره‌شناسی ایران, 2021
The rose-grain aphid, Metopolophium dirhodum is one of the most important species among wheat and barley aphids and its population trajectory in field is characterized by rapid boom. In the present study, three datasets from M.

Field-Evolved Sulfoxaflor Resistance of Three Wheat Aphid Species in China

open access: yesAgronomy, 2021
Sulfoxaflor belongs to a new class of insecticides which are effective against many sap-feeding pests. Sitobion miscanthi, Rhopalosiphum padi, and Metopolophium dirhodum are the predominant pests coexisting on wheat plants.

Treatment by glyphosate-based herbicide alters life history parameters of the rose-grain aphid Metopolophium dirhodum. [PDF]

open access: yesSci Rep, 2016
AbstractGlyphosate is the number one herbicide in the world. We investigated the sub-lethal effects of this herbicide on the aphid Metopolophium dirhodum (Walker), using an age-stage, two-sex life table approach. Three concentrations of the herbicide (low - 33.5, medium - 66.9 and high - 133.8 mmol dm−3 of active ingredient) and distilled water as the ...

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.

A diversity of endosymbionts across Australian aphids and their persistence in aphid cultures

open access: yesEnvironmental Microbiology, Volume 25, Issue 10, Page 1988-2001, October 2023., 2023
Abstract There is increasing interest in the use of endosymbionts in pest control, which will benefit from the identification of endosymbionts from potential donor species for transfer to pest species. Here, we screened for endosymbionts in 123 Australian aphid samples across 32 species using 16S DNA metabarcoding.

Indirect effect of a transgenic wheat on aphids through enhanced powdery mildew resistance. [PDF]

open access: yesPLoS ONE, 2012
In agricultural ecosystems, arthropod herbivores and fungal pathogens are likely to colonise the same plant and may therefore affect each other directly or indirectly.

Spatial distribution of cereal aphids determines their abundance and population density in winter wheat stands

open access: yesEntomologia Experimentalis et Applicata, Volume 171, Issue 10, Page 789-795, October 2023., 2023
Population density (no. individuals per unit area of ground) in sparse (ca. 80 tillers m−2) and dense (ca. 430 tillers m−2) winter wheat stands differ in two aphid species (Hemiptera: Aphididae). At the population peak (week 0) and 4 weeks before, population density in contrasting stands was similar in Sitobion avenae but different in Metopolophium ...

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.
