Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Wolbachia Infection Associated with Increased Recombination in Drosophila

G3: Genes, Genomes, Genetics, 2019
Wolbachia is a maternally-transmitted endosymbiotic bacteria that infects a large diversity of arthropod and nematode hosts. Some strains of Wolbachia are parasitic, manipulating host reproduction to benefit themselves, while other strains of Wolbachia ...

Characterization of the dynamic microbiome evolution across thrips species

Insect Science, EarlyView.
Comprehensive survey of the microbiome in thrips. The dominant bacterial genera found in thrips include intracellular ones, such as Wolbachia and Spiroplasma, and extracellular ones, including Serratia, Pantoea, and Acinetobacter. We isolated and sequenced high‐quality genomes of two dominant symbionts, Pantoea dispersa and Serratia marcescens.

Widespread Wolbachia infection in terrestrial isopods and other crustaceans

ZooKeys, 2012
Wolbachia bacteria are obligate intracellular alpha-Proteobacteria of arthropods and nematodes. Although widespread among isopod crustaceans, they have seldom been found in non-isopod crustacean species.

Exploring the potential of using male‐killing endosymbionts to induce female‐biased insect populations for enhanced biomass production

Insect Science, EarlyView.
Overview of the mindset and long‐term goals with the approach suggested in this study. We provide a first proof of concept that male‐killing endosymbionts can be used to establish female biased populations with higher production efficiency than populations with a 50/50 sex ratio. This biological tool can have marked positive impact on future commercial

Genomic evolution of the pathogenic Wolbachia strain, wMelPop [PDF]

, 2013
Most strains of the widespread endosymbiotic bacterium Wolbachia pipientis are benign or behave as reproductive parasites. The pathogenic strain wMelPop is a striking exception, however: it overreplicates in its insect hosts and causes severe life ...

A horizontally acquired pantothenate gene drives vitellogenin's benefit to whitefly symbiosis persistence

Insect Science, EarlyView.
This diagram illustrates that the horizontally transferred panBC influences the level and localization of vitellogenin (Vg) by facilitating pantothenate production and juvenile hormone (JH) biosynthesis. In turn, Vg shields symbionts by suppressing autophagic degradation in bacteriocytes.

Phenotypic Response of Wolbachia pipientis in a Cell-Free Medium

Microorganisms, 2020
Wolbachia, an obligate intracellular bacterium estimated to infect millions of arthropod species worldwide, is currently being utilized in novel control strategies to limit the transmission of Dengue and Zika viruses.

A horizontally transferred bacterial gene for pantothenic acid biosynthesis regulates diapause and reproduction in the spider mite Amphitetranychus viennensis

Insect Science, EarlyView.
A bacterial‐derived AvPBL gene encoding a pantothenate‐β‐alanine ligase was identified in Amphitetranychus viennensis. RNAi silencing of AvPBL reduced pantothenic acid production, impairing reproduction and diapause induction, while pantothenic acid supplementation rescued these phenotypes.

The wMel Wolbachia strain blocks dengue and invades caged Aedes aegypti populations

, 2011
Dengue fever is the most important mosquito-borne viral disease of humans with more than 50 million cases estimated annually in more than 100 countries. Disturbingly, the geographic range of dengue is currently expanding and the severity of outbreaks is ...
