A rhabdovirus accessory protein inhibits jasmonic acid signaling in plants to attract insect vectors.

Plant Physiology, 2022
Plant rhabdoviruses heavily rely on insect vectors for transmission between sessile plants. However, little is known about the underlying mechanisms of insect attraction and transmission of plant rhabdoviruses.

The Effect of Secondary Metabolites Produced by Serratia marcescens on Aedes aegypti and Its Microbiota

Frontiers in Microbiology, 2021
Serratia marcescens is a bacterial species widely found in the environment, which very efficiently colonizes mosquitoes. In this study, we isolated a red-pigmented S. marcescens strain from our mosquito colony (called S. marcescens VA).

Interaction between endogenous microRNAs and virus-derived small RNAs controls viral replication in insect vectors

PLoS Pathogens, 2022
MicroRNAs (miRNAs) play an important role in resisting virus infection in insects. Viruses are recognized by insect RNA interference systems, which generate virus-derived small RNAs (vsRNAs).

Frequency matters: How successive feeding episodes by blood-feeding insect vectors influences disease transmission

PLoS Pathogens, 2021
Hematophagy, the process of consuming and metabolizing blood, is an integral part of the arthropod vector life cycle. Blood feeding provides a nutrient-rich meal that is required for adult egg production and developmental progressions of immature life ...

Coordination between terminal variation of the viral genome and insect microRNAs regulates rice stripe virus replication in insect vectors

PLoS Pathogens, 2021
Maintenance of a balance between the levels of viral replication and selective pressure from the immune systems of insect vectors is one of the prerequisites for efficient transmission of insect-borne propagative phytoviruses.

Production of germ-free mosquitoes via transient colonisation allows stage-specific investigation of host–microbiota interactions

Nature Communications, 2021
Germ-free mosquitoes generated with current methods exhibit developmental deficits. Here, the authors use genetically modified bacteria to allow complete decolonisation at any developmental stage of Aedes aegypti mosquitoes and show that bacteria support

Transcription Dependent Loss of an Ectopically Expressed Variant Surface Glycoprotein during Antigenic Variation in Trypanosoma brucei

mBio, 2022
In the mammalian host, Trypanosoma brucei is coated in a single-variant surface glycoprotein (VSG) species. Stochastic switching of the expressed VSG allows the parasite to escape detection by the host immune system.

Insect Vector Transmission Assays [PDF]

, 2012
Phytoplasmas are transmitted in a persistent propagative manner by phloem-feeding vectors belonging to the order Hemiptera, suborder Homoptera. Following acquisition from the infected source plant, there is a latent period before the vector can transmit, so transmission assays consist of three basic steps: acquisition, latency, and inoculation.

Involvement of Microbiota in Insect Physiology: Focus on B Vitamins

mBio, 2023
Insects are highly successful in colonizing a wide spectrum of ecological niches and in feeding on a wide diversity of diets. This is notably linked to their capacity to get from their microbiota any essential component lacking in the diet such as ...

From Nucleotides to Satellite Imagery: Approaches to Identify and Manage the Invasive Pathogen Xylella fastidiosa and Its Insect Vectors in Europe

Sustainability, 2020
Biological invasions represent some of the most severe threats to local communities and ecosystems. Among invasive species, the vector-borne pathogen Xylella fastidiosa is responsible for a wide variety of plant diseases and has profound environmental ...
