Microbial communities play an important role in the fitness of mosquito hosts. However, factors shaping microbial wild populations, with regard to interactions among species, are still largely unknown. Previous research has demonstrated that two most studied symbionts, bacteria Wolbachia and Asaia, seem compete or not compete, depending on genetic background reference host. The large diversity Wolbachia–Asaia strain combinations infect natural populations mosquitoes may offer a relevant...
Development of large scale agro-industries are subject to serious environmental modifications. In malaria endemic areas this would greatly impact on the transmission paradigm. Two cross-sectional entomological surveys characterize Anopheles fauna and their inoculation rates were conducted during May 2010 (peak rainy season) December dry in intense rubber cultivated area Niete southern forested Cameroon. Mosquitoes sampled by night collections human volunteers, identified morphologically...
Mosquitoes are colonized by a large but mostly uncharacterized natural virome of RNA viruses, and the composition distribution may influence biology immunity Anopheles malaria vector populations. mosquitoes were sampled in endemic forest village sites Senegal Cambodia, including funestus, gambiae group sp., coustani Senegal, hyrcanus maculatus dirus Cambodia. The most frequent mosquito species at both study human vectors. Small long sequences depleted host sequences, de novo assembled...
Abstract Mosquitoes are colonized by a little-studied natural virome. Like the bacterial microbiome, virome also probably influences biology and immunity of mosquito vector populations, but tractable experimental models lacking. We recently discovered two novel viruses in wild Anopheles colonies malaria coluzzii : C virus cypovirus. Here, we describe biological interactions between these An . mosquitoes. Viral abundance varies reproducibly during development. DNA forms were not detected,...
Aedes japonicus (Diptera: Culicidae), or the Asian rock pool mosquito, is an invasive mosquito in Europe and America. It was first detected outside of Asia 1990 Oceania. has since expanded to North America 1998 2000, respectively. Even though it classified as a secondary vector pathogens, competent several arboviruses filarial worms, contributing transmission La Crosse virus (LACV) West Nile (WNV). In this study, CDC light, BG-sentinel, gravid traps were used collect mosquitoes between June...
Aedes mosquitoes are the vectors of several arboviruses that cause human disease. A better understanding their reproduction helps to improve management and contributes insights into fundamental biology mosquitoes. During mating, inseminated mosquito females receive seminal fluids sperm from males they then store in spermathecae. In aegypti albopictus , most mated become resistant further insemination within 2 h initial insemination. Although male known be involved initiating resistance...
Within the genus Aedes , reproductive biology of two species has been most thoroughly studied: aegypti and albopictus . In these species, females tend to copulate with one or more males once sexually mature. a few hours after an initial insemination, become refractory insemination for rest their lives. store sperm in three sclerotized spherical structures called spermathecae, where they can remain viable >3 mo copulation. This protocol outlines quick (∼3–5 min per female you are practiced...
Narnaviruses infect several genera of mosquitoes including Culex and Aedes . The narnavirus genome is a positive, single stranded RNA encoding an RNA-dependent polymerase gene. partial identified in wild japonicus collected Wooster, Ohio, USA was obtained using metagenomic analyses. Rapid amplification 5'-cDNA ends (RACE) Sanger sequencing were used to obtain the remaining genomic sequence this strain. complete composed 3153 nucleotides has 98.4% 99.1% nucleotide identity with genomes...
Abstract Background Mosquitoes are colonized by a large but mostly uncharacterized natural virome of RNA viruses. Anopheles mosquitoes efficient vectors human malaria, and the composition distribution may influence biology immunity malaria vector populations. Results were sampled in forest village sites Senegal Cambodia, including funestus, gambiae group sp., coustani Senegal, hyrcanus maculatus sp ., dirus Cambodia. Small long sequences depleted mosquito host de novo assembled to yield...
