Mosquitoes

Mosquitoes are known to spread vector borne diseases such as dengue fever and malaria. In Indonesia the incident rate of reported dengue fever cases increases almost every year. Syngenta provide a proven solution to overcome this problem in Indonesia.


ECONOMIC IMPORTANCE

  • Mosquitoes are vectors that carry disease-causing viruses and parasites from person to person without exhibiting symptoms themselves
  • The principal mosquito-borne diseases are the viral diseases yellow fever, dengue fever and Chikungunya transmitted mostly by the Aedes aegypti and malaria carried by the genus Anopheles sp
  • Dengue is transmitted by several species of mosquito within the Aedes genus, principally Aedes aegypti
  • The Dengue virus has four different types; infection with one type usually gives lifelong immunity to that type, but only short-term immunity to the others
  • Subsequent infection of dengue with a different type is believed to increase the risk of severe complications
  • Malaria is transmitted by the female Anopheles to humans and is caused by eukaryotic protists of the genus Plasmodium
  • Four species of Plasmodium can infect and be transmitted by humans
  • Most dangerous form of malaria is also caused by Plasmodium falciparum
  • Malaria is also caused by Plasmodium vivax, Plasmodium ovale and Plasmodium malariae, which is generally a milder disease that is rarely fatal

MOSQUITO MANAGEMENT PROGRAM

  • As there are no vaccines for malaria and dengue, prevention is done by reducing the habitat and the number of mosquitoes and limiting the exposure to bites
  • Space spraying and indoor residual spraying with a long lasting insecticide
  • Larvicide may be used to control mosquito larvae
  • Use barrier screens on windows and doors
  • Use mosquito repellent during outdoor activity
