Spiroplasma infection in Harmonia axyridis - Diversity and multiple infection.
TL;DR: The polymorphism of Spiroplasma strains in samples from individual beetles from Kyoto, Vladivostok, Troitsa Bay, Novosibirsk, and Gorno-Altaisk was investigated, finding the abundance of the heritable endosymbiotic bacterium in samples with a single infection is an order of magnitude lower than in sample with multiple infections.
The diversity of Wolbachia and its effects on host reproduction in a single Adalia bipunctata (Coleoptera: Coccinellidae) population
TL;DR: The phylogenetic relationships between the strains studied in the present work and previously published Wolbachia strains distributed globally among taxonomically unrelated insects corroborate the notion of bacterial horizontal transmission in insects, including A. bipunctata.

Symbiotic Wolbachia bacteria in coccinellid parasitoids: genetic diversity, horizontal transfer, and recombination
E. V. Shaikevich,D. A. Romanov +1 more
TL;DR: In this paper , Wolbachia was found in parasitic wasps of the genus Homalotylus and from the subfamily Tetrastichinae (Hymenoptera: Encyrtidae).
Wolbachia, Spiroplasma, and Rickettsia symbiotic bacteria in aphids (Aphidoidea).
TL;DR: It was found that six species of aphids are infected with Rickettsia that are genetically different from previously known, and both maternal inheritance and horizontal transmission are the pathways for the distribution of facultative endosymbiotic bacteria in aphids.
Sequence Polymorphism of the Mitochondrial DNA Control Region in Native and Invasive Populations of Harmonia axyridis (Coleoptera, Coccinellidae)
TL;DR: Haplotype diversity is maximal in the population of the Harmonia axyridis eastern population group and is reduced in the invasive population and the stability of the haplotype composition in the European invasive population in the process of the invasive range expansion was demonstrated.
