In 1966, its presence was declared in the rural part of Chrui Chang War, a district facing Phnom Penh, located on the eastern side of the Mekong River. albopictus is known to originate from Southeast Asia, and known from Cambodia, its presence was never attested in the capital city. Today, it mainly occurs in suburban and rural areas. Human migration favoured its spread into new areas, and it rapidly became an opportunistic container breeder, using either natural or artificial containers, having the ability to survive in small collections of water in tires, plastic buckets, and plastic cups. This species is a competent vector for all four serotypes of dengue and can transmit at least 22 arboviruses. feeding on wildlife), progressively adapted to anthropogenic changes to the environment, which provided alternative blood sources (domestic animals and humans) and water collections for larval habitats. The latter species, originating from the forests of Southeast Asia, where it was likely zoophilic (i.e. The two main mosquito species responsible for the transmission of dengue virus are Aedes aegypti (Linnée, 1789) and Aedes albopictus (Skuse, 1894). The multiple potential mosquito breeding sites created in the urban centre can favour vector proliferation, particularly dengue vectors. Hosting about 2.13 million of the 15.3 million inhabitants of Cambodia, Phnom Penh is a rapidly developing city. In 20, the capital Phnom Penh city was terribly affected as never before with respectively 94 cases (Ministry of Health, Phnom Penh, Cambodia). Major dengue epidemics outbreaks happened in 2007 (39,618 cases with 396 deaths), 2012 (42,362 cases with 189 deaths) and 2019 (68,597 cases with 48 deaths) (Ministry of Health, Phnom Penh, Cambodia). In Cambodia, since the massive epidemic in 1995, accounting for more than 400 deaths, the number of cases has been monitored every year. Their geographical spread is increasing: while only 5 countries documented dengue cases in the 1950s, more than 100 countries reported the incidence of dengue fever and dengue haemorrhagic fever in 2005. Dengue fever and dengue haemorrhagic fever are two of the most important mosquito-borne viral diseases of public health significance.
