What is a Green Mosquito?

Green mosquitos are a species found in Singapore that carry disease and are active all year. They carry parasite that causes Dengue Fever.


What do they look like?

The green mosquito is not a new mosquito species; they resemble the other common mosquitoes with some slight distinction. They are mosquitoes from the species Aedes aegypti.

The research team working on controlling the dengue virus in Singapore infected the mosquitoes with the Wolbachia parasite. This infection made the mosquitoes sterile, thus help to prevent the spread of the dengue virus.

These mosquitoes are small in size, with very small heads and large eyes. In addition, the green mosquitoes have an abdomen, thorax, and very slender legs, which are usually six.

The color of these mosquitoes ranges from blue or green markings to greyish-brown white or black markings. The team didn’t alter with any of the genetic make-ups.

They are a project of an Austrian research team developed to sterilize the dengue virus in any infected mosquito. The project’s objective was to ensure that the dengue virus doesn’t reach the maturity stage. Only the virus that reaches maturity is capable of causing the disease to people.

The team infected the mosquitoes with the Wolbachia bacteria parasite. Only the male mosquitoes were infected with the parasite, and later the research team released the male mosquitoes.

This parasite has various mechanisms to shorten the fruit fly’s life cycle. The group thought that the parasite would also shorten the life of the mosquitoes before the virus develops. Thus, the strategy was to achieve the reduction of transmission of the disease.

The research team had a strategy for the mechanism to work in the following way. When the male mosquitoes are infected by the Wolbachia parasite ( the Wolbachia carrier) mates with a female mosquito, they get sterile.

However, its eggs can still be carrying the disease that the research team infected it with, but the disease micro-organism can’t cause the disease as they aren’t yet mature. Thus, when these mosquitoes bite you, they can’t transmit the disease as they are sterile. Remember, during the release, the parasite wasn’t infected on the other mosquitoes and insect species.


Where are the green mosquitoes found?

You can mainly see the green mosquitoes in Zika Singapore. Because the team that had Wolbachia-Aedes suppression strategy was targeting to reduce the primary dengue vector in Zika, Singapore. They infected the male mosquitoes with the Wolbachia parasite and released them in Zika to control the dengue virus.


Are green mosquitoes dangerous?

Green mosquitoes are not dangerous as the Australian team used the male to control the killer disease in the subtropical countries. The researchers found the best ways to control the dengue, which was becoming rampant.

Dengue fever has severe flu-like symptoms infecting over 50 million people annually worldwide. Many strategies to prevent the disease, including using pesticides, haven’t bore fruits. However, using green mosquitoes has worked well to help control the spread of the deadly dengue virus spread by the mosquitoes.

However, when the male green mosquitoes mate with the female that is not a carrier of the Wolbachia parasite, then the female eggs may get infected, and later, they can transmit the disease to the human being they’ve bitten.


Green mosquitoes vs. regular mosquitoes

The research team used the green mosquitoes from the Aedes aegypti species though the team used them as Wolbachia parasite carriers. However, there are various comparisons between the green mosquitoes and the regular mosquitoes. The comparisons are based on what the mosquitoes carry, body structure, geographical distribution, and the disease they transmit.

1. The research team uses the green mosquitoes to control the spread of dengue; thus, the male green mosquitoes are carriers of the Wolbachia parasite. While the regular mosquitoes aren’t used for scientific research, they mainly transmit the malaria plasmodium to the human being they bite.

2. The regular mosquitoes usually bite people regularly during the night or when the individuals are in a dark place where they are present. In contrast, the green mosquitoes of the Aedes species don’t bite people regularly.

3. Regular mosquitoes are found in most places globally; they don’t have restrictions on the places or regions where they are found. In contrast, to the green mosquitoes, which are only common in subtropical countries such as Singapore.

4. The green mosquitoes of the species Aedes aegypti are well known for transmitting several viruses like the dengue virus, zika virus, and chikungunya virus. In contrast to the regular mosquitoes like the female anopheles mosquitoes, which are only known to transmit malaria to human beings.

5. The regular mosquitoes complete their life cycle. The life cycle may last 7-14 days from the eggs to the adult. However, green mosquitoes have a shorter life cycle. The life cycle is generally attributed to the experiment by the Australian team to ensure the Wolbachia parasite doesn’t get to maturity, thus controlling the spread of the dengue virus.

6. Lastly, the green mosquitoes are usually active throughout the year, having the peak in August, September, and October. In comparison, the regular mosquitoes are generally very active during the rainy seasons when there is a lot of water and good places to breed and make their habitat.

The green mosquitoes are a species of the mosquito species Aedes aegypti that the research team uses to controls the dengue virus. The Australian team used the mosquitoes to control the deadly dengue virus by making them carriers of the Wolbachia parasite.

The mosquitoes are common in the subtropical countries where the experimental studies were done. Lastly, these mosquitoes possess slightly different features when you compare them with the other regular mosquitoes.
