A Systematic Review of the Natural Virome of Anopheles Mosquitoes

Viruses, 2018
Anopheles mosquitoes are vectors of human malaria, but they also harbor viruses, collectively termed the virome. The Anopheles virome is relatively poorly studied, and the number and function of viruses are unknown. Only the o’nyong-nyong arbovirus (ONNV)

Insulated piggyBac vectors for insect transgenesis [PDF]

BMC Biotechnology, 2006
Abstract Background Germ-line transformation of insects is now a widely used method for analyzing gene function and for the development of genetically modified strains suitable for pest control programs. The most widely used transposable element for the germ-line transformation of insects is piggyBac.

Gene copy number and function of the APL1 immune factor changed during Anopheles evolution

Parasites & Vectors, 2020
Background The recent reference genome assembly and annotation of the Asian malaria vector Anopheles stephensi detected only one gene encoding the leucine-rich repeat immune factor APL1, while in the Anopheles gambiae and sibling Anopheles coluzzii, APL1

Circadian rhythms in insect disease vectors [PDF]

Memórias do Instituto Oswaldo Cruz, 2013
Organisms from bacteria to humans have evolved under predictable daily environmental cycles owing to the Earth's rotation. This strong selection pressure has generated endogenous circadian clocks that regulate many aspects of behaviour, physiology and metabolism, anticipating and synchronising internal time-keeping to changes in the cyclical ...

Microbial Pre-exposure and Vectorial Competence of Anopheles Mosquitoes

Frontiers in Cellular and Infection Microbiology, 2017
Anopheles female mosquitoes can transmit Plasmodium, the malaria parasite. During their aquatic life, wild Anopheles mosquito larvae are exposed to a huge diversity of microbes present in their breeding sites.

The Role of Temperature in Shaping Mosquito-Borne Viruses Transmission

Frontiers in Microbiology, 2020
Mosquito-borne diseases having the greatest impact on human health are typically prevalent in the tropical belt of the world. However, these diseases are conquering temperate regions, raising the question of the role of temperature on their dynamics and ...

Impact of temperature on dengue and chikungunya transmission by the mosquito Aedes albopictus

Scientific Reports, 2022
The mosquito Aedes albopictus is an invasive species first detected in Europe in Albania in 1979, and now established in 28 European countries. Temperature is a limiting factor in mosquito activities and in the transmission of associated arboviruses ...

Immune responsiveness in vector insects [PDF]

Proceedings of the National Academy of Sciences, 1997
Insects have been particularly successful in evolution, and current estimates are that they represent three-quarters of all extant animal species. With the marked exception of the seas, insects occupy nearly all ecological niches on earth and hence are confronted to innumerable potential pathogenic bacteria, viruses, fungi, and protozoan and helminth ...

Application of Genomics for Understanding Plant Virus-Insect Vector Interactions and Insect Vector Control [PDF]

Phytopathology®, 2016
The relationships between plant viruses and their vectors have evolved over the millennia, and yet, studies on viruses began <150 years ago and investigations into the virus and vector interactions even more recently. The advent of next generation sequencing, including rapid genome and transcriptome analysis, methods for evaluation of small RNAs ...

A Review: Wolbachia-Based Population Replacement for Mosquito Control Shares Common Points with Genetically Modified Control Approaches

Pathogens, 2020
The growing expansion of mosquito vectors has made mosquito-borne arboviral diseases a global threat to public health, and the lack of licensed vaccines and treatments highlight the urgent need for efficient mosquito vector control.
