El ciclo urbano es endemo/epidemico y los vectores involucrados son Aedes aegypti y Aedes albopictus
, en donde la distribucion del virus sigue la distribucion del vector de las zonas urbanas de paises tropicales, subtropicales y en la actualidad de paises de climas templados.
Chikungunya virus is a mosquito-borne alphavirus transmitted primarily by Aedes aegypti and Aedes albopictus
mosquitoes, which also transmit dengue virus and are found throughout much of the Americas, including parts of the U.
The researchers have also tested three additional insect species - the Asian Tiger mosquito Aedes albopictus
, the fruit fly Drosophila melanogaster, and the jewel wasp Nasonia vitripennis - and found that their sperm also contain odorant receptors.
The feeding behavior of Aedes albopictus
is very catholic," says Duane Gubler, a vector-borne disease expert at Duke-National University of Singapore.
Epidemiological implications of aedes albopictus
(Skuse) in Colombia
The Asian tiger mosquito, Aedes albopictus
, has already been reported in France and Belgium and could be migrating north as winters become warmer and wetter.
Probablemente, esto es debido a que los procesos de competencia generados entre Aedes albopictus
(Skuse) y A.
Aedes aegypti (9) and Aedes albopictus
are usually considered as potential vectors of CHIKV since they have been proven susceptible to this virus in many laboratory studies.
They warned, for example, that population suppression of Aedes aegypti could lead to a closely related and disease-transmitting mosquito species, Aedes albopictus
, filling the vacated niche and continuing to cause, or even worsen, the dengue problem, or transmission of other serious diseases.
9:30 THE EFFECTS OF SALT TOLERANCE ON INTERSPECIFIC COMPETITION BETWEEN AEDES ALBOPICTUS
AND AEDES AEGYPTI
, the Asian tiger mosquito, is one of the most invasive mosquito species known and a vector for at least 22 viruses, including West Nile virus and dengue.
Potential dengue outbreaks are a public health concern in south Texas due to the vector activity of Aedes aegypti and Aedes albopictus
(Micks, & Moon, 1980; Mitchell, Miller, & Gubler, 1987) as well as endemic transmission in adjoining northern Mexico.
