Symbiotic microbial studies in diverse populations of Aphis gossypii, existing on altered host plants in different localities during different times

open access: yesEcology and Evolution, 2021
Complex interactions between symbiotic bacteria and insects ultimately result in equilibrium in all aspects of life in natural insect populations. In this study, abundance of principal symbiotic bacteria was estimated using qPCR in 1553 individuals of ...

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

open access: yesInsects, 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 ...

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

open access: yesScientific 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,

Aphids on Aphid-Susceptible Cultivars Have Easy Access to Turnip Mosaic Virus, and Effective Inoculation on Aphid-Resistant Cultivars of Oilseed Rape (Brassica napus)

open access: yesPlants, 2023
Plant viruses improve transmission efficiency by directly and indirectly influencing vector behavior, but the impact of plant cultivars on these modifications is rarely studied.

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

open access: yesProceedings 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.

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

open access: yesProceedings 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

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

open access: yesFrontiers 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.

Plant defense against aphids, the pest extraordinaire.

open access: yesPlant Science, 2019
Aphids are amongst the most damaging pests of plants that use their stylets to penetrate the plant tissue to consume large amounts of phloem sap and thus deprive the plant of photoassimilates.

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

open access: yes, 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.

Population dynamic and damage of the Mealy Almond Aphid Hyalopterus amygdali on thirteen commercial cultivars of almonds in Chaharmahal and Bakhtiari Province, Iran [PDF]

open access: yesنامه انجمن حشره‌شناسی ایران
Aphid Hyalopterus amygdali (Blanchard, 1840) is one of the important pests of almond in Chaharmahal and Bakhtiari province. Population fluctuation and damage caused by this aphid were studied during two years (2022- 2023) on thirteen commercial cultivars
