Aedes aegypti
It is a medium-sized black-colored mosquito having a silvery-white “lyre-shaped” pattern on its scutum or shield
Like its cousin, Ae. albopictus, it also has banded white stripes on its legs
Presence & Activity
Originally from Africa, Ae. aegypti is present in most tropical and sub-tropical regions.
It is an urban mosquito preferring households living close together.
Ae. aegypti never lives more than 90 meters from dwellings.
It prefers clean, shady, stagnant water.
The mosquito’s lifetime ranges from 8 to 16 days.
Dengue cases from mid-August to mid-September 2010
Food and Blood
Like the albopictus and Anopheles mosquitoes, females need human blood for egg development.
Why do female Aedes need blood? A study in 1977 reported
that the human blood’s isoleucine is important for egg production.
There is a positive correlation between the level of isoleucine in blood and the number of eggs produced.
Diseases
Ae. aegypti is a biological vector for transmitting: Yellow fever
Viral hemorrhagic disease only found in Africa and South America.
Chikungunya In the Makonde language,
“that leans downward.” Causes illness similar to
dengue with prolonged joint pains that can last for years.
Present in Africa and Asia. Dengue Fever
Aedes is the primary vector
Yellow fever virus
Dengue virus
Chikungunya virus
