The Zika virus rampaged through the Americas in 2015 and 2016, charging out of Brazil and into neighboring countries inside the Aedes aegypti and Aedes
albopictus mosquitoes.
Grelloni V, Biasini G. (2002) Detection of Aedes
albopictus in the province of Perugia (Umbria).
albopictus presence in the traps during any period of time was mapped to the native WorldClim 30 arcsec (approximately 1 × 1 km) grid.
This is an Aedes
albopictus female mosquito obtaining a blood meal from a human host.
«Although a different chikungunya virus strain from the Asian lineage is now circulating in the Americas, the introduction of the Indian Ocean lineage could put temperate regions where A.
albopictus thrives at risk for expansion of epidemic circulation,» Weaver cautioned.
The second also included areas with Aedes aeqypti occurrence and the third included both A. aeqypti and A.
albopictus occurrence — these scenarios each increased the size of the region at risk.
The mosquitoes known as Aedes aegypti and Aedes
albopictus transmit arboviruses that are increasing threats to human health in the Americas, particularly dengue, chikungunya, and Zika viruses.
albopictus blood meals and were the second most common host in Culex samples, behind birds.
Aedes
albopictus adults were collected in three states (Pennsylvania, New Jersey, New York) covering most of the known geographic range of this species in northeastern USA.
The researchers also included data for
A. albopictus — better known as the Asian tiger mosquito — which can harbor the virus.
And some parts of the U.S. are vulnerable to outbreaks: The Aedes aegypti and Aedes
albopictus mosquitoes that spread the infection are alive and well in many Southern states.
The studies found that transmission of dengue, and other arboviruses by Aedes aegypti and
Aedes albopictus mosquitoes, has been found to occur between 18 - 34 °C (64 to 93 °F) with maximal transmission in the range of 26 - 29 °C (78 to 84 °F).
albopictus in Panama is very related to European populations, this could have implications for the introduction of emergent arboviruses like chikungunya and Zika from Europe into Panama.
The U.S. Environmental Protection Agency has approved using a strain of male Asian tiger mosquitoes (Aedes
albopictus) as a biopesticide in the District of Columbia and 20 states, including California and New York.
Already today, the secondary dengue mosquito, Aedes
albopictus, has established in the Mediterranean region.
The African strain has been accumulating mutations that allow it to be spread more easily by Aedes
albopictus.
In the early 1980s, Aedes
albopictus, a mosquito species native to Southeast Asia that spreads dengue fever and yellow fever, turned up deep in the American South.
As a result, the two species of mosquito capable of transmitting dengue fever — Aedes aegypti and Aedes
albopictus, also called the Asian tiger mosquito — have substantially expanded their habitat range since the middle of the 20th century.
Bulstrode also points out that transmission is unlikely in the UK as the mosquitoes that carry Zika — Aedes aegypti and Aedes
albopictus — can't survive in the country, and that most people who get glioblastoma are over 50, so the risks of passing it on to a pregnant woman through sex are low.
albopictus, which can transmit the same diseases but thrives over a much larger range.
But the Asian tiger mosquito, Aedes
albopictus, comes with some particularly irritating characteristics.
albopictus, which can render U.S. backyards uninhabitable as well as spread viruses.
In the United States, A.
albopictus has a greater range than A. aegypti.
albopictus mosquitoes that hatched tested positive for Zika RNA (ribonucleic acid), meaning that females collected in the field had encountered Zika and passed fragments of the virus to their offspring.
«Our results mean that Aedes
albopictus may have a role in Zika virus transmission and should be of concern to public health,» Smartt says.
albopictus can «vertically transmit» live Zika virus to its offspring is still unclear.
«Anywhere with these vectors — Aedes aegypti mosquitoes and to some degree Aedes
albopictus — could get this virus and have local transmission,» says Erin Staples, a medical epidemiologist and expert in mosquito - borne diseases at the U.S. Centers for Disease Control and Prevention.
