Approximately, there are 3,600 species of mosquito and the word “mosquito” originate from spanish that means “little fly”. They have narrowed segment body, a set of wings, pair of halter, six mildly hair legs, and needle life mouth part. Not all mosquitoes live to feed on blood of mankind or animals. When bitten, most common reactions are itching, inflammation and swelling bumps.

Only some type of mosquito can be categorise and label as vectors. Vectors are animal, insect, or ticks that are capable to spreads virus (germs) to humans. Example of viruses and parasites that aedes aegypti mosquitoes transmits. They can make you suffer from mosquito dengue virus, yellow fever virus, chikungunya virus and zika virus.

West nile virus is a virus transmitted to humans through bites from an infected culex mosquito. Some mosquitoes do not spread germs when the bite occurs. These type of adult mosquitoes that are categorise as nuisance mosquitoes. The female mosquitoes require a blood meals to produce mosquito eggs.

Dengue viruses are transmit to humankind through the stealth bite of an infect mosquito aedes species (Aegypti or Albopictus). The white stripes mosquitoes are well known to spread zika, chikungunya, and various mosquito borne disease. About half of the world’s population, that is approximately 4 billions of people, live in places with a risk of dengue. Dengue is frequently the main reason for illnesses in areas with uncontrolled breeding sites and higher risk red zone.

Every year, approximately 400 millions of people get infect with dengue fever. Approximately 100 millions of people fall sick from the transmit diseases infections. And around 40,000 dies from severe dengue virus symptoms. Unfortunately, people can be infect by the virus multiple times in their lifetime.

NEA Environmental Health Institute have made various intensive studies to prevent and mosquito control methods. They have found that the project wolbachia aedes suppression technology is the most suitable for Singapore. Experts from Singapore, Australia, and United States recommends that Singapore explore the method of the wolbachia mosquito suppression technology. This will help to provide the results to further reduce the risk to public health of dengue cases and virus transmission.

The releases of male wolbachia mosquitoes in Singapore have significantly reduced the aedes aegypti mosquito populations. Study sites listed such as Yishun, Tampines, Choa Chu Kang and Bukit Batok resulting by going up to about 98%. The exact locations of the study sites shown after at least a year of releases have jumped to 88% lower.
