Microbiome diversity of cotton aphids (Aphis gossypii) is associated with host alternation

Scientific Reports, 2021
Aphids are infected by a series of bacteria that can help them survive on specific host plants. However, the associations between aphids and these bacteria are not clear, and the bacterial communities in many aphid species are poorly characterized. Here,

The miR-9b microRNA mediates dimorphism and development of wing in aphids

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance Evolution of various wings plays an important role in the success of insects in environmental adaptation. During evolution, aphids deploy a wing dimorphism strategy to escape unfavorable conditions.

Influence of Bacterial Secondary Symbionts in Sitobion avenae on Its Survival Fitness against Entomopathogenic Fungi, Beauveria bassiana and Metarhizium brunneum

Insects, 2022
The research was focused on the ability of wheat aphids Sitobion avenae, harboring bacterial secondary symbionts (BSS) Hamiltonella defensa or Regiella insecticola, to withstand exposure to fungal isolates of Beauveria bassiana and Metarhizium brunneum ...

Coordination of host and symbiont gene expression reveals a metabolic tug-of-war between aphids and Buchnera

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance Symbioses between animals and microbes often involve host control of symbionts to harness a benefit. In aphids, Buchnera symbionts produce amino acids for their hosts, enabling these insects to survive solely on plant sap. Buchnera abundance

Grass Hosts of Cereal Aphids (Hemiptera: Aphididae) Between Wheat-Cropping Cycles in South Dakota [PDF]

, 2018
Several grasses may serve as alternative hosts for cereal aphids during the interim between small-grain crops in South Dakota, but field studies to determine which grasses are important have not been undertaken.

Novel Temporal Expression Patterns of EBF-Binding Proteins in Wing Morphs of The Grain Aphid Sitobion miscanthi

Frontiers in Physiology, 2021
High chemosensitivity of insects to volatile organic compounds (VOC) stimuli is mediated by odorant binding proteins (OBPs). In aphids, three OBPs (OBP3, OBP7 and OBP9) are E-β-farnesene (EBF)-binding proteins.

Treating green pea aphids, Myzus persicae, with azadirachtin affects the predatory ability and protective enzyme activity of harlequin ladybirds, Harmonia axyridis

Ecotoxicology and Environmental Safety, 2021
As a natural enemy of green peach aphids, harlequin ladybirds, Harmonia axyridis Pallas (Coleoptera: Coccinellidae), are also indirectly affected by azadirachtin.
