The endosymbiont Spiroplasma poulsonii increases Drosophila melanogaster resistance to pathogens by enhancing iron sequestration and melanization

mBio
Facultative endosymbiotic bacteria, such as Wolbachia and Spiroplasma species, are commonly found in association with insects and can dramatically alter their host physiology.

Endosymbiont-free ants: Molecular biological evidence that neither Wolbachia, Cardinium or any other bacterial endosymbionts play a role in thelytokous parthenogenesis in the harvester ant species, Messor barbarus and M. capitatus (Hymenoptera: Formicidae)

European Journal of Entomology, 2013
Thelytokous parthenogenesis is a type of sex determination in which females are produced from unfertilized eggs. Genetic and endosymbiont-induced forms of thelytoky have been described in the Hymenoptera. Our study has revealed that Wolbachia, Cardinium,

When Does Fungicide Use Pay Off in Maize? Evidence From Low Foliar Disease Pressure Environments in Southern Brazil

Journal of Phytopathology, Volume 174, Issue 3, May/June 2026.
ABSTRACT Foliar fungicides are widely used in maize production in southern Brazil, yet their economic justification under low disease pressure remains uncertain. We synthesised yield and economic responses to a fungicide programme using a random‐effects meta‐analytic approach based on 19 multi‐environment trials conducted across the first and second ...

Challenging the Wigglesworthia, Sodalis, Wolbachia symbiosis dogma in tsetse flies: Spiroplasma is present in both laboratory and natural populations

Scientific Reports, 2017
Profiling of wild and laboratory tsetse populations using 16S rRNA gene amplicon sequencing allowed us to examine whether the “Wigglesworthia-Sodalis-Wolbachia dogma” operates across species and populations. The most abundant taxa, in wild and laboratory

Elevated Temperatures Disrupt Wolbachia‐Induced Feminisation and Reshape Microbial Community Dynamics Across Generations in a Spider Host

Molecular Ecology, Volume 35, Issue 9, May 2026.
ABSTRACT Longitudinal microbial interactions within a host are challenging to study, leading to a focus on constructed microbial communities in vitro settings. Here, we take advantage of a naturally defined microbial community within a spider host to study how elevated temperatures influence microbial dynamics and phenotypes across host generations ...

Geographical Divergence and Environmental Drivers of the Symbiotic Bacterial Community Structure in a Koelreuteria‐Feeding Aphid Species Complex

Ecology and Evolution, Volume 16, Issue 4, April 2026.
This study investigates the symbiotic bacteria in the Periphyllus koelreuteriae aphid species complex, revealing an inverse relationship between the dominant symbionts Buchnera and Serratia. The relative abundance of these symbionts is strongly influenced by latitude and minimum winter temperature, suggesting that heat stress drives their ...

Video_1_Prospects for the Mechanism of Spiroplasma Swimming.MP4

, 2021
Spiroplasma are helical bacteria that lack a peptidoglycan layer. They are widespread globally as parasites of arthropods and plants. Their infectious processes and survival are most likely supported by their unique swimming system, which is unrelated to

Understanding the distribution of the Spiroplasma heritable bacterial endosymbiont in Drosophila [PDF]

, 2010
Symbiosis can be a major source of evolutionary innovation and a driver of ecological diversification. Insects, in particular, partner with a diversity of heritable bacterial endosymbionts that affect them in myriad ways, ranging from mutualistic to ...

Identification of Spiroplasma insolitum symbionts in Anopheles gambiae [version 1; referees: 2 approved, 1 not approved]

Wellcome Open Research, 2017
Background: Insect symbionts have the potential to block the transmission of vector-borne diseases by their hosts. The advancement of a symbiont-based transmission blocking strategy for malaria requires the identification and study of Anopheles symbionts.

Dietary Specialisation Shapes Gut Bacterial Diversity in Dung Beetles: Insights From Coprophagy to Millipede Carnivory

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Dung beetles feed on various food sources that are rich in microbial life. Here, we describe how the diets of seven dung beetle species, specialising in coprophagy, necrophagy, detritophagy, fungivory and carnivory influence their gut bacterial structure and diversity.
