Side‐stepping secondary symbionts: widespread horizontal transfer across and beyond the Aphidoidea
TLDR
Findings on the prevalence of these symbionts within many aphid taxa, along with published observations concerning their effects on host fitness, imply a significant role of facultative symbiosis in aphid ecology and evolution. Expand
Host–based divergence in populations of the pea aphid: insights from nuclear markers and the prevalence of facultative symbionts
TLDR
This study clearly demonstrates that populations of A. pisum on pea, clover and alfalfa in France are genetically divergent, which indicates that they constitute distinct host races, and stresses the need for phylogeographic studies to shed light on the process of host–race formation and acquisition of facultative symbionts in this aphid.

Extreme genome reduction in Buchnera spp.: Toward the minimal genome needed for symbiotic life
TLDR
Evidence is shown of six species with a genome size smaller than Mycoplasma genitalium, the smallest bacterial genome reported thus far, which strongly suggest that the Buchnera genome is still experiencing a reductive process toward a minimum set of genes necessary for its symbiotic lifestyle. Expand
The ground beetle Pseudophonus rufipes revealed as predator of Ceratitis capitata in citrus orchards
TLDR
Data reported here clearly suggest that P. rufipes could play an important role in regulating medfly populations in citrus orchards, and is particularly useful when biological control conservation strategies are being considered to control this pest. Expand
PHYLOGENETIC EVIDENCE FOR HYBRID ORIGINS OF ASEXUAL LINEAGES IN AN APHID SPECIES
TLDR
This study constitutes another example that putatively ancient asexual lineages are actually of much more recent origin than previously thought, and presents a robust approach for testing whether hybrid origin of asexuality is also a common phenomenon in aphids. Expand
Deciphering reproductive polyphenism in aphids
TLDR
A physiological model of the determination of sexual vs. asexual reproduction in aphids is proposed and viewed from the perspective of newly initiated molecular studies. Expand
Tracking medfly predation by the wolf spider, Pardosa cribata Simon, in citrus orchards using PCR-based gut-content analysis
TLDR
This study is the first to reveal the potential use of DNA markers to track medfly predation by P. cribata in citrus orchards and provides a new tool to estimate the potential role of this spider in biological-control conservation programs. Expand
The evolution of the heat-shock protein GroEL from Buchnera, the primary endosymbiont of aphids, is governed by positive selection.
TLDR
The main conclusion derived from the analysis is that GroEL has suffered an accelerated rate of amino acid substitution upon the symbiotic integration of Buchnera into the aphids. Expand
Large-scale gene discovery in the pea aphid Acyrthosiphon pisum (Hemiptera)
TLDR
This project is the first to address the genetics of the Hemiptera and of a hemimetabolous insect with a catalog of 12,082 unique transcripts. Expand
Plasmids in the aphid endosymbiont Buchnera aphidicola with the smallest genomes. A puzzling evolutionary story.
TLDR
The analysis of three B. aphidicola strains belonging to aphids from different tribes of the subfamily Lachninae, that was estimated to harbour the bacteria with the smallest genomes, indicates the existence of many recombination events in a recA minus bacterium and that plasmids are also involved in the genome shrinkage process.
