Abstract 1. Natural populations of pea aphids in California contain at least two facultative bacterial secondary symbionts (pea aphid secondary symbiont, PASS, or pea aphid rickettsia, PAR) in a range of frequencies throughout the state. 
Linking the bacterial community in pea aphids with host‐plant use and natural enemy resistance
TLDR
Pea aphids, Acyrthosiphon pisum, harbour a range of facultative accessory bacteria (secondary symbionts), including those informally known as PASS, PAR,PABS, PABS (T‐type), and PAUS (U‐type).
The significance of a facultative bacterium to natural populations of the pea aphid Acyrthosiphon pisum
TLDR
PABS, also known as T‐type, is distributed widely but is not universal in natural populations of the pea aphid Acyrthosiphon pisum in the U.K.
Grain aphid clones vary in frost resistance, but this trait is not influenced by facultative endosymbionts
TLDR
There is no data on whether heritable facultative endosymbionts in any species affect their hosts' performance at low temperatures, something that could have a major effect on insect physiology and survival, and thus population structure and distribution.
Faithful vertical transmission but ineffective horizontal transmission of bacterial endosymbionts during sexual reproduction of the black bean aphid, Aphis fabae
TLDR
Insects are commonly infected with bacterial endosymbionts, and their rates of vertical and horizontal transmission are important determinants of symbiont prevalence.
The natural occurrence of secondary bacterial symbionts in aphids
TLDR
A model system to study insect–bacteria interactions in aphids and its effects on host‐plant use and resistance against natural enemies is proposed.
Pea Aphid
The pea aphid (Acyrthosiphon pisum (Harris)) is a common insect found wherever pulses are grown in Saskatchewan. Pea aphids cause damage to their host plants by sucking plant sap. They can reduce
The Plant–Aphid Universe
Aphids belong to the suborder Sternorrhyncha, which contains the aphids, whiteflies, psyllids, and scale insects, groups which are included in the order Hemiptera (Table 1). Sternorrhyncha refers to
Genomic revelations of a mutualism: the pea aphid and its obligate bacterial symbiont
TLDR
A refined picture of the A. pisum/Buchnera APS symbiosis is presented by linking pre-genomic observations to new genomic data that includes the complete genomes of the eukaryotic and prokaryotic symbiotic partners.

TLDR
The biology of a new genomic model system, the pea aphid, Acyrthosiphon pisum, is reviewed to become an important model system for understanding the molecular and developmental basis of many ecologically and evolutionarily relevant problems.

Spiroplasma Symbiont of the Pea Aphid, Acyrthosiphon pisum (Insecta: Homoptera)
TLDR
A previously unknown facultative endosymbiotic bacterium is discovered from a laboratory strain of the pea aphid, Acyrthosiphon pisum, which molecular phylogenetic analysis based on 16S ribosomal DNA revealed is a member of the genus Spiroplasma.
Pea aphid symbiont relationships established by analysis of 16S rRNAs
TLDR
Comparisons with sequences of 16S rRNAs from selected procaryotes indicate that the two symbionts are evolutionarily distinct from each other and are members of the gamma-3 subdivision of the class Proteobacteria.

Fitness effects of two facultative endosymbiotic bacteria on the pea aphid, Acyrthosiphon pisum, and the blue alfalfa aphid, A. kondoi
TLDR
Alate production in pea aphids was significantly increased in large populations of two PASS‐ and PAR‐positive subclones relative to their parent clones, and this ameliorative effect of facultative bacteria at 25 °C was not found for two other sets of parent clones and their derived sub clones.
A New Rickettsia from a Herbivorous Insect, the Pea Aphid Acyrthosiphon pisum (Harris)
TLDR
An undescribed, maternally heritable, rod-shaped bacterium was detected by microscopy in hemolymph of about half of pea aphid clones collected from widely separated locations in California, the first confirmed detection of a Rickettsia in a herbivorous insect.
Populations of symbiotic bacteria in the parthenogenetic pea aphid (Acyrthosiphon pisum) symbiosis
TLDR
The growth and division of the bacteria in the maternal tissues varied with aphid developmental age, with evidence for a restriction of bacterial division rates in fourth-instar larvae.

Abstract. The occurrence of a secondary bacterial symbiont (PASS) of pea aphid, Acyrthosiphon pisum (Harris), was detected by polymerase chain reaction (PCR) with specific nucleotide primers based

TLDR
The population of symbiotic Buchnera bacteria in parthenogenetic females of the pea aphid Acyrthosiphon pisum was determined by quantitative hybridization of a DNA probe (groESL) to aphid homogenates to show variation in the density of bacteria in the embryos and embryo content of the aphids.
