The Significance of Genetic Relatedness and Nest Sharing on the Worker‐Worker Similarity of Gut Bacterial Microbiome and Cuticular Hydrocarbon Profile in a Sweat Bee

Ecology and Evolution, Volume 15, Issue 6, June 2025.
The relationship between cuticular hydrocarbon (CHC) profile and the gut microbiome (GM) is poorly known in bees. In the primitively eusocial bee Halictus scabiosae we found a high rate of nest‐drifting by workers, which leads to a consequent highly variable intra‐colonial genetic relatedness. Genetically closely related workers, even occupying distant

A survey of Wolbachia, Spiroplasma and other bacteria in parthenogenetic and non-parthenogenetic phasmid (Phasmatodea) species

European Journal of Entomology, 2015
The ecological and genetic mechanisms that determine Phasmatodea reproductive biology are poorly understood. The order includes standard sexual species, but also many others that display distinct types of parthenogenesis (tychoparthenogenesis, automixis,

Genome analysis of Spiroplasma citri strains from different host plants and its leafhopper vectors

BMC Genomics, 2020
Background Spiroplasma citri comprises a bacterial complex that cause diseases in citrus, horseradish, carrot, sesame, and also infects a wide array of ornamental and weed species. S.

Comparative Analyses of Gut Microbiomes in Hycleus cichorii (Coleoptera: Meloidae) Adults Reveal Their Distinct Microbes, Microbial Diversity and Composition Associated to Food

Ecology and Evolution, Volume 15, Issue 2, February 2025.
The study analyzed the gut microbial diversity and composition of H. cichorii with different dietary habits and genders. The results showed that an elevated richness in food composition corresponds to a higher diversity of gut microbial species in the host. It suggests that food plays a significant role in the composition of the gut microbial community,

Understanding maize genotype behavior under stunt complex pressure [PDF]

Ciência e Agrotecnologia
The stunt complex, transmitted by Dalbulus maidis, has become one of the main maize diseases in recent years in Brazil and Latin America. Genetic resistance is one of the best ways to control and prevent plant diseases due to its efficiency, low ...

Symbiont-mediated fly survival is independent of defensive symbiont genotype in the Drosophila melanogaster-Spiroplasma-wasp interaction

bioRxiv, 2020
When a parasite attacks an insect, the outcome is commonly modulated by the presence of defensive heritable symbionts residing within the insect host.

Defensive Symbiont Genotype Distributions Are Linked to Parasitoid Attack Networks

Ecology Letters, Volume 28, Issue 2, February 2025.
Facultative symbionts are widespread in arthropods and can provide important services such as protection from natural enemies. Yet what shapes defensive symbiont associations in nature remains unclear. We show that the symbiont Hamiltonella defensa's genotype distribution strongly aligns with sharing the same parasitoids, rather than host plants ...

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

Characterisation of the bacteriomes harboured by major wireworm pest species in the Canadian Prairies

Insect Molecular Biology, Volume 34, Issue 1, Page 203-217, February 2025.
The bacteriomes of five of the most important agricultural pests in the Canadian Prairies were characterised. Wireworms have diverse and taxon‐rich bacterial communities, with different species having a distinct composition and a small number of genera predominating.

Is Alzheimer's Disease Infectious?
Relative to the CJD Bacterial Infection Model of Neurodegeneration

AIMS Neuroscience, 2015
Alzheimer's disease (AD) has been recently considered as a possible brain infection related to the Creutzfeldt-Jakob disease (CJD) transmissible dementia model.
