Effect of temperature on some biological aspects and the thermal requirements of Diaeretiella rapae (M'Intosh) (Hymenoptera:Braconidae) reared on Rhopalosiphum padi L. (Homoptera: Aphididae) [PDF]
Assiut University Bulletin for Environmental Researches, 2021 Developmental periods, adult longevity and thermal requirements of Diaeretiella rapae (M'Intosh) were investigated at 18, 20, 22 and 24°C constant temperature. The development durations decreased as the temperature increased. At 24°C and 18°C the periods

Barley Yellow Dwarf Virus Influences Its Vector’s Endosymbionts but Not Its Thermotolerance
Microorganisms, 2023 The barley yellow dwarf virus (BYDV) of cereals is thought to substantially increase the high-temperature tolerance of its aphid vector, Rhopalosiphum padi, which may enhance its transmission efficiency.

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.

Matrine–Tea Saponin Synergism Involves Suppressed Detoxification and Digestion in a Leaf Beetle
Integrative Zoology, EarlyView.Tea saponin and matrine showed synergistic toxicity against Plagiodera versicolora. Combined exposure suppressed digestion‐ and detoxification‐related processes, while silencing the trypsin gene Pver105950 and chitinase gene Pver001190 increased larval susceptibility to tea saponin and matrine, respectively.

Journal of Integrative Agriculture, 2019 Sitobion avenae (F.) and Rhopalosiphum padi (L.) are two important pests of wheat in China. They typically coexist in fields during the late period of wheat growth. Sulfoxaflor is a novel sulfoximine insecticide that demonstrates broad-spectrum efficacy,

Agricultural and Forest Entomology, EarlyView.Four‐year field monitoring and laboratory studies revealed M. dirhodum occurs regularly in barley with high reproductive potential and extended adult longevity. Populations peaked during vulnerable crop stages, creating optimal conditions for BYDV transmission during critical infection windows. M.

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.

Resistance of wheat cultivars to bird cherry-oat aphid, Rhopalosiphum padi (Hem.: Aphididae) [PDF]
نامه انجمن حشرهشناسی ایران, 2011 The bird cherry-oat aphid, Rhopalosiphum padi (L.), is polyphagous with a nearly worldwide distribution and known as an important pest of wheat and the main vector of barley yellow dwarf virus.

Ecological Entomology, EarlyView.Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.
