Adults are 3 to 6 mm long, piercing and sucking mouth-parts
Mosquito Life Cycle
All mosquitoes have four stages of development – egg, larva, pupa and adults – and spend their larval and pupa stages in water.
After the female mosquito obtains a blood meal (male mosquitoes do not bite), she lays her eggs directly on the surface of the stagnant water, in a depression, or on the edge of a container where rainwater may collect and flood the eggs. The eggs hatch and a mosquito larva or “wriggler” emerges. The larva lives in the water, feed and developes into the third stage of the life cycle called a pupa or “tumbler”. The pupa also lives in the water, but no longer feeds. Finally, the mosquito emerges from the pupal case and the water as a fully developed adult, ready to bite.
When the adult mosquitoes emerge from the aquatic stages, they mate, and the female seeks a blood meal to obtain the necessary protein for the development of her eggs. The female of a few species may produce a first batch of eggs without this first blood meal. After a blood meal is digested and the eggs are laid, the female mosquito again seeks a blood meal to produce a second batch of eggs. Depending on her stamina and the weather, she may repeat this process many times without mating again.
The male mosquito does not take a blood meal, but may feed on plant nectar, honeydew or plant secretions. He lives for only a short time after mating.
The whole life cycle normally complete in a week.
What Attracts Mosquitoes
Mosquitoes are attracted by perspiration, warmth, body odor, carbon dioxide and LIGHT.
What you can do to help fight mosquitoes
Physical Control Methods
- Empty standing water in old tires, buckets, plastic covers or any other container where “wrigglers” and “tumbler” live.
- Empty and change the water in wading pools and potted plant trays on a very frequent basis.
- Keep rain gutters unclogged.
- Make sure window and door screens are “bug tight.”
- Replace your outdoor lights with yellow “bug” lights.
Chemical Control Methods
- Fogging: Pesticides will be release in the form of smoke /fog
- Misting: Pesticides will be release in the form of mist / minute droplet
- Mosquito Repellent: Applied on skin or clothes, active for a few hours only
- Larvicide: Applied in larval breeding sites
- Surface spray: Residual spraying of surface known to be frequented by mosquitoes
- Space treatment: Widely use for rapid relief from mosquito annoyance
