ABSTRACT Bacterial endosymbionts of the pine bark adelgid, Pineus strobi (Insecta: Hemiptera: Adelgidae), were investigated using transmission electron microscopy, 16S and 23S rRNA-based phylogeny, and fluorescence in situ hybridization. Two morphologically different symbionts affiliated with the Gammaproteobacteria were present in distinct bacteriocytes. One of them (“Candidatus Annandia pinicola”) is most closely related to an endosymbiont of Adelges tsugae, suggesting that they originate… 
Evolutionary recent dual obligatory symbiosis among adelgids indicates a transition between fungus and insect associated lifestyles
TLDR
Genomic characteristics and metabolic pathway reconstructions revealed that Vallotia and Profftia are evolutionary young endosymbionts, which complement each other’s role in essential amino acid production.
Evolutionarily recent dual obligatory symbiosis among adelgids indicates a transition between fungus- and insect-associated lifestyles
TLDR
Genomic characteristics and metabolic pathway reconstructions revealed that Vallotia and Profftia are evolutionary young endosymbionts, which complement each other’s role in essential amino acid production.
Symbiotic cornucopia of the monophagous planthopper Ommatidiotus dissimilis (Fallén, 1806) (Hemiptera: Fulgoromorpha: Caliscelidae)
TLDR
Both molecular and microscopic analyses of the symbiotic system of the planthopper Ommatidiotus dissimilis have revealed that all the symbionts are transovarially transmitted between generations.
Buchnera has changed flatmate but the repeated replacement of co-obligate symbionts is not associated with the ecological expansions of their aphid hosts
TLDR
It is proposed that symbiont succession was driven by factors intrinsic to the phenomenon of endosymbiosis, such as rapid genome deterioration or competitive interactions between bacteria with similar metabolic capabilities.
Relationships between aphid species of the family Adelgidae (Hemiptera Adelgoidea) and their endosymbiotic bacteria: a case study in Lithuania
TLDR
Cophylogenetic analyses based on aphid partial COI and EF-1α sequences and 16S rRNA gene fragment of their endosymbiotic bacteriae showed reliable cophylogenetics events confirming the importance of host aphid species relatedness in structuring symbiont communities of adelgid aphid Species.
Partnering With a Pest: Genomes of Hemlock Woolly Adelgid Symbionts Reveal Atypical Nutritional Provisioning Patterns in Dual-Obligate Bacteria
TLDR
Investigation of the symbionts of Adelges tsugae, the hemlock woolly adelgid (HWA), an invasive species introduced from Japan to the eastern United States, finds that both symbiont provide nutrients, but in more balanced proportions than dual symbions of other hemipterans.
Dynamic Acquisition and Loss of Dual-Obligate Symbionts in the Plant-Sap-Feeding Adelgidae (Hemiptera: Sternorrhyncha: Aphidoidea)
TLDR
The consistency of symbionts within and across adelgid lineages was explored, and evidence for facultative vs. obligate symbiont status was sought, with a hypothesis relating adelGid life cycles to relaxed constraints on Symbionts is proposed.
Buchnera aphidicola of the birch blister aphid, Hamamelistes betulinus (Horváth, 1896) (Insecta, Hemiptera, Aphididae: Hormaphidinae): molecular characterization, transmission between generations and its geographic significance
TLDR
Ulastructural and molecular analyses did not reveal the presence of secondary symbionts in the body of H. betulinus, and the concept of the relationship between the geographic distribution of Hormaphidini aphids and the presence/absence of bacterium Buchnera aphidicola is discussed.
Aphids of the family Adelgidae in Lithuania: distribution, host specificity and molecular (mitochondrial COI and nuclear EF-1α) diversity
Based on the original research of 2017–2018, also reference data, four aphid species and five species complexes of the family Adelgidae listed for Lithuanian fauna. Pineus (Pineus) strobi (Hartig,
Transitional genomes and nutritional role reversals identified for dual symbionts of adelgids (Aphidoidea: Adelgidae)
TLDR
The sequence and compare genomes of four additional dual-symbiont pairs in adelgids show that these symbionts are nutritional partners originating from diverse bacterial lineages and exhibiting wide variation in general genome characteristics.

Bacteriocyte-associated gammaproteobacterial symbionts of the Adelges nordmannianae/piceae complex (Hemiptera: Adelgidae)
TLDR
The first molecular identification of bacteriocyte-associated symbionts in these plant sap-sucking insects is presented, suggesting vertical transmission from mother to offspring.
Co-evolution and symbiont replacement shaped the symbiosis between adelgids (Hemiptera: Adelgidae) and their bacterial symbionts.
TLDR
All symbionts were present in all adelgid populations and life stages analysed, suggesting vertical transmission from mother to offspring and there is evidence for co-evolution between the gammaproteobacterial symbiontes.
Diversity of proteobacterial endosymbionts in hemlock woolly adelgid (Adelges tsugae) (Hemiptera: Adelgidae) from its native and introduced range.
TLDR
Investigation of bacterial symbionts of Adelges tsugae, a pest of hemlocks in eastern North America introduced from Asia, supports the ideas that symbiont gain and loss has been volatile in adelgids, and that Symbionts may help to trace the source of invasive species.

TLDR
The identification and first molecular characterization of symbiotic bacteria in cixiid planthoppers (tribe: Pentastirini) is reported and 'Candidatus Purcelliella pentastirinorum' was proposed as the novel gammaproteobacterial symbiont.

TLDR
Results suggest that, unlike the primary endosymbiont, Arsenophonus may infect whiteflies multiple times and may also be horizontally transmitted.

TLDR
This study reports and describes the finding of an additional bacterium in the indigenous B. tabaci cryptic species China 1 and temporarily named it Orientia-like organism (OLO), which belongs to the Alphaproteobacteria subdivision of the Proteobacteria and has a close relationship with human pathogens of the genus Orientia.
