Gene regulation by mating depends on time, diet, and body region in female Aedes aegypti.

Aedes aegypti is a major vector of several arboviruses that cause human mortality and morbidity. One method for controlling the spread of these viruses is to control mosquito reproduction. During mating, seminal fluid molecules and sperm are transferred and these stimuli influence female post-mating physiology and behavior.

and Distribution among Different Mosquito Vectors Is Affected by Tissue Localization and Host Species.

Microbial communities play an important role in the fitness of mosquito hosts. However, the factors shaping microbial communities in wild populations, with regard to interactions among microbial species, are still largely unknown. Previous research has demonstrated that two of the most studied mosquito symbionts, the bacteria and , seem to compete or not compete, depending on the genetic background of the reference mosquito host.

Complete genome of narnavirus from wild caught mosquitoes collected in Ohio, USA.

Narnaviruses infect several genera of mosquitoes including and . The narnavirus genome is a positive, single stranded RNA encoding an RNA-dependent RNA polymerase gene. The partial genome of a narnavirus identified in wild mosquitoes collected in Wooster, Ohio, USA was obtained using metagenomic analyses.

Factors enhancing the transmission of mosquito-borne arboviruses in Africa.

Unlabelled: Arthropod-borne viruses (Arboviruses) replicate in vertebrates and invertebrates and are mainly transmitted by mosquitoes. Between 2000 and 2021, several arbovirus outbreaks were recorded in African countries, including dengue, yellow fever, Chikungunya, Zika, and O'nyong nyong. Most often, the causes and factors involved in these outbreaks are unknown.

Determining the Insemination Status of Mosquitoes.

Within the genus , the reproductive biology of two species has been most thoroughly studied: and In these species, females tend to copulate with one or more males once sexually mature. Within a few hours after an initial insemination, most females become refractory to insemination for the rest of their lives. females store sperm in three sclerotized spherical structures called spermathecae, where they can remain viable for >3 mo after copulation.

Insemination in and .

mosquitoes are the vectors of several arboviruses that cause human disease. A better understanding of their reproduction helps to improve their management and contributes insights into the fundamental biology of mosquitoes. During mating, inseminated mosquito females receive seminal fluids and sperm from males that they then store in the spermathecae.

Effects of Mating on Gene Expression in Female Insects: Unifying the Field.

There is intense interest in controlling insect reproductive output. In many insect species, reproductive output is profoundly influenced by mating, including the receipt of sperm and seminal fluid molecules, through physiological and behavior changes. To understand these changes, many researchers have investigated post-mating gene expression regulation.

Correction to: De novo profiling of RNA viruses in Anopheles malaria vector mosquitoes from forest ecological zones in Senegal and Cambodia.

Following the publication of this article [1], the authors reported that the original shading in columns 3 and 4 of Table 3, which indicated the presence or absence of viruses in each library, had been removed during typesetting.

De novo profiling of RNA viruses in Anopheles malaria vector mosquitoes from forest ecological zones in Senegal and Cambodia.

Background: Mosquitoes are colonized by a large but mostly uncharacterized natural virome of RNA viruses, and the composition and distribution of the natural RNA virome may influence the biology and immunity of Anopheles malaria vector populations.

Results: Anopheles mosquitoes were sampled in malaria endemic forest village sites in Senegal and Cambodia, including Anopheles funestus, Anopheles gambiae group sp., and Anopheles coustani in Senegal, and Anopheles hyrcanus group sp.

Interaction of RNA viruses of the natural virome with the African malaria vector, Anopheles coluzzii.

Mosquitoes are colonized by a little-studied natural virome. Like the bacterial microbiome, the virome also probably influences the biology and immunity of mosquito vector populations, but tractable experimental models are lacking. We recently discovered two novel viruses in the virome of wild Anopheles and in colonies of the malaria vector Anopheles coluzzii: Anopheles C virus and Anopheles cypovirus.

A Systematic Review of the Natural Virome of Anopheles Mosquitoes.

mosquitoes are vectors of human malaria, but they also harbor viruses, collectively termed the virome. The virome is relatively poorly studied, and the number and function of viruses are unknown. Only the o'nyong-nyong arbovirus (ONNV) is known to be consistently transmitted to vertebrates by mosquitoes.
