Immunity and other defenses in pea aphids, Acyrthosiphon pisum [PDF]

open access: goldGenome Biology, 2010
Abstract Background Recent genomic analyses of arthropod defense mechanisms suggest conservation of key elements underlying responses to pathogens, parasites and stresses. At the center of pathogen-induced immune responses are signaling pathways triggered by the recognition of fungal, bacterial and viral ...

Comparative transcriptomics of aphid species that diverged > 22 MYA reveals genes that are important for the maintenance of their symbiosis

open access: yesScientific Reports, 2023
Most plant-sap feeding insects have obligate relationships with maternally transmitted bacteria. Aphids require their nutritional endosymbiont, Buchnera aphidicola, for the production of essential amino acids.

Silencing of two insulin receptor genes disrupts nymph-adult transition of alate brown citrus aphid [PDF]

open access: yes, 2017
Insulin receptors play key roles in growth, development, and polymorphism in insects. Here, we report two insulin receptor genes (AcInR1 and AcInR2) from the brown citrus aphid, Aphis (Toxoptera) citricidus.

The Influence of Host Aphids on the Performance of Aphelinus asychis

open access: yesInsects, 2022
The aphid parasitoid Aphelinus asychis Walker is an important biological control agent against many aphid species. In this study, we examined whether the rearing host aphid species (the pea aphid, Acyrthosiphon pisum and the grain aphid, Sitobion avenae)

Acyrthosiphon pisum

open access: yesTrends in Genetics, 2019
Aphids are sap-sucking insects that comprise about 5500 species colonizing a wide variety of host plants. They are the dominant group (26%) among insect pests of the six main crops grown for human consumption, with the potential to cause a worldwide economic impact.
