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.

EMS Mutagenesis in the Pea AphidAcyrthosiphon pisum [PDF]

open access: yesG3 Genes|Genomes|Genetics, 2014
AbstractIn aphids, clonal individuals can show distinct morphologic traits in response to environmental cues. Such phenotypic plasticity cannot be studied with classical genetic model organisms such as Caenorhabditis elegans or Drosophila melanogaster. The genetic basis of this biological process remain unknown, as mutations affecting this process are ...

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)

Expansion of the miRNA Pathway in the Hemipteran Insect Acyrthosiphon pisum [PDF]

open access: yesMolecular Biology and Evolution, 2010
The pathways that allow short noncoding RNAs such as the microRNAs (miRNAs) to mediate gene regulation and control critical cellular and developmental processes involve a limited number of key protein components. These proteins are the Dicer-like RNases, double-stranded RNA (dsRNA)-binding proteins, and the Argonaute (AGO) proteins that process stem ...

Gene knockdown by RNAi in the pea aphid Acyrthosiphon pisum [PDF]

open access: yesBMC Biotechnology, 2007
RNA interference (RNAi) is a powerful method to inhibit gene expression in a sequence specific manner.Here, we described the development of RNAi by micro-injection of double-stranded RNA (dsRNA) in the pea aphid Acyrthosiphon pisum. Injection of dsRNA into whole aphid body induced the silencing of two marker genes with different expression patterns ...

Effect of innate preferences, conditioning and adult experience on the attraction of Aphidius ervi (Hymenoptera: Braconidae) toward plant volatiles

open access: yesEuropean Journal of Entomology, 2002
The aphid parasitoid Aphidius ervi was collected and subsequently reared on Sitobion avenae on wheat or Acyrthosiphon pisum on alfalfa. Parasitoids from both origins were exposed in an olfactometer to alfalfa or wheat volatiles after plant experience ...

An investigation on alfalfa aphids and their parasitoids in different parts of Iran, with a key to the parasitoids (Hemiptera: Aphididae; Hymenoptera: Braconidae: Aphidiinae) [PDF]

open access: yesنامه انجمن حشره‌شناسی ایران, 2006
In the current study some information is presented about the distribution and associations between alfalfa aphids and their parasitoids in different regions in 11 provinces of Iran, as well as an identification key to the parasitoids.
