The female mosquitos have a very broad host range and can attack humans, amphibians, reptiles and births (Eritja et al. 2005). It was recorded in one survey of biting rates a level of 30 to 48 bites per hour (Cancrini et al. 2003). Ae. albopictus has the potential to carry and transmit a wide range of viruses; in laboratory it is proven that is capable to transmit seven alphaviruses, (e.g. Eastern Equine encephalitis and Ross River viruses) and it has been also proven in the laboratory that Ae. Albopictusis has the ability to carry and transmit eight bunyaviruses (e.g., Lacrosse and Rift Valley fever viruses), furthermore the species has the potential to develop three flaviviruses, (i.e. Japanese encephalitis, West Nile, and yellow fever) to human (Mitchell 1995, Shroyer 1986). All these viruses are very harmful to human and other organisms, they causes several diseases to humans. For instance in 2007 there was an outbreak of chikungunya in Italy, and other cases of dengue viruses were reported in south France and Croatia. The dengue virus is known to have four strains, therefore attacking one strain doesn’t immunize against contracting the other strains, so it become so difficult to treat the diseases caused by this virus. Chikungunya virus causes fever, swelling and redness of joints, severe rheumatic pains and in some cases death; according to research in various lab it has been shown that when a person is repeatedly infected with dengue viruses, this increases the risk of more severe sickness such as DenguhocyndromSS which induces shock as a result of a sharp drop in the volume of blood which might also lead to

From the gentlest to the most fatal, the Ebola trio is ranked as Marburg, Ebola Sudan, and Ebola Zaire. However, in a quest to determine a new strain of Ebola, scientists discover a harmless-to-humans but fatal-to-monkeys agent known as Ebola Reston. Marburg virus can affect humans like nuclear radiation by virtually damaging all the tissues in their bodies. Ebola and Marburg are both viruses that cause hemorrhagic fevers, organ failures, brain damage, and death.

Hawaii Invasive Species Essay

3398 Words | 14 Pages

Invasive species have been a massive problem in Hawaii since the 17s and 18 hundreds. At first, it wasn’t that big of a deal, but the influx of invasive species grew over time, and it became a dangerous slippery slope. Species that were once alienated poured into Hawaii and destroyed indigenous species that had been native to Hawaii for a very long time. Since then, the Hawaiian people and advocates of removing invasive plants and animals have banded together to help remove these species. There has been a great global effort to remove invasive species in all places, but the hasty spread of them has made it almost impossible to eradicate a lot of them. I think my group can majorly help with this by educating you all about the seriousness of invasive species.

Pros And Cons Of Invasive Species

1618 Words | 7 Pages

Invasive Species Invasive, alien species, those which colonise, expand and out compete native species (Smith & Smith, 2009), are a major threat to our habitats, terrestrial and aquatic species, and biodiversity. Agricultural and leisure industries are affected as well as conservation welfare and the continued wellbeing of man, flora and fauna. Whole ecosystems can be distorted and the economic cost of awareness, prevention and eradication systems is substantial. Most invasive species have been introduced by mandeliberately or otherwise. As an island, Ireland has been subjected to less invasive species than larger nearby land masses e.g. Europe, but islands have a less diverse species population and are therefore more vulnerable when invaded.
