Life cycle of the Aedes Aegypti Mosquito

Aedes Aegypti Life Cycle

The dengue mosquito (dengue Machar) Aedes mosquito or Aedes aegypti mosquito is one of the only few types of mosquitoes that spread dengue disease. Aedes mosquitoes are visually distinctive because they have noticeable black and white markings on their body and legs. Unlike most other mosquitoes, they are active and bite only during the daytime. The peak biting periods are early in the morning and in the evening before dusk. The Aedes Aegypti Life Cycle depends very much on the level of feeding.

Aedes Aegypti life-cycle is complex with dramatic changes in shape, function, and habitat. Female mosquitoes lay their eggs on the inner, wet walls of containers with water.

How long does it take for mosquito eggs to become adults?

The eggs of aedes mosquito can lie dormant in dry conditions for up to about nine months, after which they can hatch if exposed to favorable conditions, i.e. water and food.

Aedes mosquito life cycle begins with the larvae hatching when water inundates the eggs as a product of rains or the addition of water by people. In the following days, the larvae will feed on microorganisms and particulate organic matter, shedding their skins three times to be able to nurture from first to fourth instars.

Pupae do not feed; they just change in form until the body of the adult, flying mosquito is formed. Then, the newly formed adult emerges from the water after breaking the pupal skin. The total Aedes aegypti life cycle lasts 8-10 days at a room temperature, depending on the level of feeding. 

How long does the Aedes aegypti or dengue mosquito (dengue Machar) live?

The adult Aedes Aegypti life cycle can range from two weeks to a month depending on ecological conditions.

Biological details of Dengue mosquito (dengue Machar)

Male mosquitoes are slightly smaller in size compared to female mosquitoes and the female mosquitoes feed on blood because the protein in the blood helps them develop the eggs. Mosquitoes are attracted to heat and lactic acid and tend to bite people who have just exercised, bigger people attract mosquitoes more because they produce higher carbon dioxide & lactic acid. Female dengue mosquito lays about 30 – 300 eggs at one time

The mosquito becomes infective approximately seven days after it has bitten a person carrying the virus. This is the extrinsic incubation period, during which time the virus replicates in the mosquito and reaches the salivary glands.

Habitat of Dengue mosquito (dengue machar)

Dengue mosquitoes or Aedes mosquito have unusual breeding sites frequently found in domestic containers, flower pot plates/trays, ornamental containers. They also hide and breed in toilet bowls, closed perimeter drains and gully traps, AC vents, water coolers.

Any place where water gets accumulated and stays stagnant for over few days becomes a breeding ground for these aedes mosquitoes.

Do a quick check of your home and bungalow to identify any potential breeding spots in monsoon season.

What attracts dengue mosquitoes (dengue machar)?

According to a new experiment, the presences of flowers have known to have an effect on the egg-laying behavior as mosquitoes drink nectar from flowers.

The carbon dioxide we exhale and the sweat we generate is what attracts mosquitoes. When it combines with the bacteria making us vulnerable to the mosquitoes. When it comes to the blood type as well, mosquitoes have a peculiar taste to a specific blood group. Studies have shown that mosquitoes are most attracted to Type O blood and least attracted to Type A. Mosquitoes are also more attracted to people with a greater build-up of lactic acid on their skin.

It  is therefore necessary  to have regular pest control services in your home and make sure to hire an expert for mosquito control service. After all, a pest free home is a healthy home!
