Aedes cinereus Wiedemann, 1818. [Aedes cinereus is traditionally credited to Meigen (1818) but the heading “Aedes cinereus Hoffmgg,” and the description are both in quotation marks, followed by a statement that clearly shows that Meigen did not know or describe the species. Wiedemann apparently described the species and used a Hoffmansegg manuscript name (Sabrosky, 1999).]
Subfamily Culicinae, tribe Aedini. The traditional Aedes, sensu Wilkerson et al. (2015), is a very large genus with 935 species divided among 78 subgenera (all but two recognised as genera in the preferred phylogenetic classification of tribe Aedini established by Reinert et al., 2009). Genus abbreviation – Ae.
Aedes are often difficult to distinguish from other aedine genera because of the great diversity of subgenera and species which are defined by various combinations of characters that overlap with other members of the tribe. The spectrum of polymorphism that occurs in the tribe is also found in the traditional concept of Aedes.
ADULTS ‒ Adults are usually differentiated from those of other aedine genera by the following combination of characters: antepronota usually rather small and widely separated, prespiracular setae absent, postspiracular setae nearly always present, mesopostnotal setae usually absent, base of hindcoxa usually below base of mesomeron, base of subcosta without ventral patch of setae, and apex (tip) of the abdomen of females usually, but not always, more or less pointed.
LARVAE ‒ Larvae are difficult to distinguish from those of Haemagogus in the New World and Heizmannia, Udaya and Zeugnomyia in the Oriental Region. The treatments of these genera should be consulted for features that distinguish them from Aedes. The following combination of characters is usually used to recognise Aedes larvae: metathoracic pleural group of setae well developed, a single pair of seta 1-S inserted near or beyond middle of siphon (species of subgenera Aedes and Rusticoidus have more than one pair of seta 1-S) and pecten apparently always present (represented by one or more spines on each side of the siphon). See Aedini.
Little can be said about the phylogenetic relationships of Aedes because it is a highly polyphyletic group. In the phylogeny of mosquito genera generated in the study of Harbach & Kithcing (1998), Aedes was recovered in an unresolved assemblage involving Eretmapodites and a clade comprised of Opifex in a basal relationship to Psorophora + Mansoniini. Soghigian et al. (2017) included two or more species for each of 26 subgenera of Aedes (classification of Wilkerson et al., 2015) in their molecular phylogenetic study of Aedini: Acartomyia, Aedes, Aedimorphus, Bothaella, Bruceharrisonius, Catageiomyia, Collessius, Diceromyia, Dobrotworskyius, Downsiomyia, Georgecraigius, Halaedes, Howardina, Hulecoeteomyia, Jarnellius, Lorrainea, Macleaya, Mucidus, Neomelaniconion, Ochlerotatus, Paraedes, Phagomyia, Rhinoskusea, Rusticoidus, Stegomyia and Tanakaius. All but six of these genus-group taxa were recovered as monophyletic. Aedimorphus, Catageiomyia and Neomelaniconion in Clade A (corresponding to genus Aedes of Reinert, 2000) and Collessius, Ochlerotatus and Phagomyia in Clade B (corresponding to genus Ochlerotatus of Reinert, 2000) were not monophyletic. However, the monophyly of Collessius, Neomelaniconion and Phagomyia was violated by species with only a single genetic marker.
Aedes is the dominant group of mosquitoes from the tropics to the arctic. Some species also occur at high altitudes. The immature stages of Aedes develop exclusively in temporary collections of water, including ground-pools, snow pools, rock holes, tree holes, bamboo, leaf axils, artificial containers, and brackish water swamps and pools. Females of all species lay eggs on surfaces subject to being flooded or inundated by water. Those that oviposit in cavities such as tree holes, leaf axils or domestic containers attach their eggs to the walls of the cavity just above the water. Eggs have a capacity for resisting desiccation for months or a year or more. Mating of all species probably takes place in the immediate vicinity of the larval habitats. Females of many species readily attack humans, some during the daylight hours and others at night.
Aedes includes species that transmit yellow fever, dengue and other arboviruses. A few species also transmit the helminths that cause Brugian and Bancroftian filariasis. Stegomyia is the most important subgenus of Aedes from a medical point of view. It includes Aedes aegypti, the classical vector of urban yellow fever and dengue fever viruses. Aedes aegypti is widely distributed through the tropical and subtropical areas of the world. Other important vectors include Ae. africanus and Ae. bromeliae, which transmit yellow fever virus in Africa, and Ae. albopictus, an important vector of dengue fever virus in the Oriental Region. The latter species has been introduced into the USA and countries Central and South America, Europe and Africa. Other important vectors of dengue fever virus include Ae. scutellaris, Ae. pseudoscutellaris and Ae. polynesiensis in the Pacific Islands. The latter two species also transmit the helminths which cause Bancroftian filariasis.
Aedes vexans of subgenus Aedimorphus has an extensive distribution in tropical Africa, Central America, Southeast Asia, and temperate regions of the Nearctic and Palaearctic Regions. The adults are annoying and persistent biters which can be involved in the transmission of arboviruses. A few species of subgenus Finlaya, including Ae. poicilius, Ae. togoi, Ae. kochi, Ae. niveus and Ae. harinasutai, are important vectors of arboviruses and microfilariae in the Oriental Region. Two species of subgenus Diceromyia, Ae. taylori and Ae. furcifer, are implicated in the transmission of yellow fever virus and the spread of Chikungunya virus in Africa. A few medically important species belong to subgenus Ochlerotatus. Aedes vigilax transmits the agents of Bancroftian filariasis in New Caledonia and several viruses (e.g. Ross River virus) in Australia. Aedes sierrensis and Ae. atlanticus are important vectors of dog heartworm (Dirofilaria immitis) in North America. A few other species transmit various arboviruses, mainly those that cause encephalitis. Aedes triseriatus, subgenus uncertain, is an important vector of the California group of encephalitis viruses. See Table 1 of Wilkerson et al. (2015) for a detailed list of medically important species.
Aedes has a world-wide distribution, but is not so well represented in the Neotropical Region. Most of the subgenera occur in the Oriental and Australasian Regions.
