Albopictus Subgroup

Type species: 

Aedes albopictus (Skuse, 1895), original combination: Culex albopictus.

Classification: 

Subfamily Culicinae, genus Aedes, subgenus Stegomyia, Scutellaris Group. The Albopicctus Subgroup includes 11 species, one with three subspecies.

Characteristics: 

ADULTS ‒ Species of the Albopictus Subgroup differ from species of the Scutellaris Subgroup in having an ill-defined supraalar line of naroow pale scales over the base of the wing. MALE GENITALIA ‒ Group characters not apparent. LARVAE and PUPAE ‒ Seemingly without group characters (Huang, 1972). See Scutellaris Group and subgenus Stegomyia.

Phylogenetic relationships: 

Sota & Mogi (2006) examined the evolutionary relationships of 11 species of subgenus Stegomyia based on sequence data for COI mtDNA and 16S and 28S rRNA: one species of the Aegypti Group (Ae. aegypti), one from the Maehleri Group (Ae. maehleri), one of the Pseudonigeria Group (Ae. wadai) and nine of the Scutellaris Group, including three from the Albopictus Subgroup (Ae. albopictus, Ae. flavopictus, Ae. galloisi) and five from the Scutellaris Subgroup (Ae. dybasi, Ae. hensilli, Ae. palauensis, Ae. riversi, Ae. scutellaris). Their results do not support the monophyly of the Albopictus Subgroup. Aedes albopictus and Ae. flavopictus were recovered as sister species in trees derived from the individual genes and the combined data set, but Ae. galloisi was only united with these two species based on the analysis of COI sequences.

Bionomics and disease relations: 

The immature stages of species of the Albopictus Subgroup are known to occupy a variety of habitats, including tree holes, log holes, tree and bamboo stumps, bamboo cups, coconut shells, coconut husks, pitcher plants, rock holes, rock pools, leaf axils (including axils of Allocasia, banana, Colocasia, Nipa, Pandanus and pineapple) and artificial containers. Females of most species attack humans.

Aedes albopictus is an important vector of dengue fever virus in Southeast Asia and has been shown to harbour and be capable of transmitting other viruses (Huang, 1972; references cited in Wilkerson et al., 2015).

Distribution: 

Species of the Albopictus Subgroup have distributions in the Oriental Region and the eastern Palaearctic, spanning an area from Pakistan, India and Nepal eastward to Vietnam and from southern Siberia southward to Indonesia. Aedes albopictus has been transported to all other regions and continents by human agency.
