How Cabbage Aphids Brevicoryne brassicae (L.) Make a Choice to Feed on Brassica napus Cultivars

open access: yesInsects, 2019
Plant resistance to aphids might be present in different plant tissues, such as the epidermis, mesophyll and phloem, but not all of them play a key role in determining the feeding preference of aphids.

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,

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.

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

A novel gene REPTOR2 activates the autophagic degradation of wing disc in pea aphid

open access: yeseLife, 2023
Wing dimorphism in insects is an evolutionarily adaptive trait to maximize insect fitness under various environments, by which the population could be balanced between dispersing and reproduction. Most studies concern the regulatory mechanisms underlying
