Aedes(also known as thetiger mosquito[1]) is agenusofmosquitoesoriginally found in tropical andsubtropical zones,but now found on allcontinentsexceptAntarctica.Some species have been spread byhuman activity:Aedes albopictus,a particularlyinvasive species,was spread to theAmericas,including theUnited States,in the 1980s, by theused-tire trade.[2]

List of Aedes species

First described and named byGermanentomologistJohann Wilhelm Meigenin 1818, thegeneric namecomes from theAncient Greekἀηδής,aēdēs,meaning 'unpleasant' or 'odious'. Thetype speciesforAedesisAedes cinereus.[3]

Systematics and phylogeny

edit
Aedes (Stegomyia) pia,described in 2013.[4]

The genus was named byJohann Wilhelm Meigenin 1818. The generic name comes from the Ancient Greekἀηδής,aēdēs,meaning 'unpleasant'[5]or 'odious'.

As historically defined, the genus contains more than 950species(see thelist ofAedesspecies). The genus has been divided into severalsubgenera(Aedes,Diceromyia,Finlaya,Stegomyia,etc.), most of which have been recently treated by some authorities as full genera.[6]The classification was revised in 2009.[7]

Characteristics

edit

Aedesmosquitoes are visually distinctive because they have noticeable black and white markings on their bodies and legs. Unlike most other mosquitoes, they are active and bite onlyduring the daytime.The peak biting periods are early in the morning and in the evening before dusk.[8][9]

Direct children of this genus

edit

The genus contains 28 species that are not placed in a further subgenus:[10]

Children with uncertain position

As disease vectors

edit

Members of the genusAedesare known vectors for numerous viral infections, includingdengue fever,yellow fever,theZika virus,[11]andchikungunya,which are transmitted by species in the subgenusStegomyiasuch asA. aegyptiandA. albopictus.[12]Infections with these viruses are typically accompanied by a fever, and in some cases, encephalitis, which can lead todeath.Avaccineto provide protection from yellow fever exists, and measures to prevent mosquito bites includeinsecticidessuch asDDT,mosquito traps,insect repellents,mosquito nets,and pest control usinggenetically modified insects.[13]InPolynesia,the speciesAedes polynesiensisis responsible for the transmission ofhuman lymphatic filariasis.

Aedescan be detected and monitored byovitraps.

Sequencing

edit

The genome of the yellow fever mosquito (Aedes aegypti) was sequenced by theBroad Instituteandthe Institute for Genomic Research.The initial assembly was released in August 2005; a draft sequence of the genome and preliminary analysis was published in June 2007.[14]The annotated genome is available atVectorBase.[15]An updated and improved version of theAedes aegyptigenome was released in 2018.[16]
