4. Why?
It transmits
• Dengue fever – deadly killer of mankind
particularly children
• Chikungunya - a crippling fever
5. Characteristics of the
Aedes Mosquito
It bites during the day
It lays its eggs in
clean, shady, stagnant
water
One distinct physical
feature – black and
white strips on its body
and legs-Hence called
“Tiger Mosquitoes”
6. Life Cycle of Aedes sp. Vector
Egg
1.5 – 3 days
Adult Larva
21 days 6 – 8 days
Pupa
1.5 – 3 days
8. Man made Aedes farms
• Water storage tank or • Discarded food and
cistern drink containers
• Drums • Used tyres
• Flower vase filled with • Discarded large
water appliances
• Potted plants with • Discarded buckets
saucers • Rubber collection shells
• Roof gutters
9. Man made Aedes farms
• Animal water • Tender cocunut shells
container • Plastic covers used for
• Air coolers covering fruits in the
• Water coolers trees
• Discarded tins • Air conditioners
• Window gutters
44. Vector Bionomics
Eggs withstand desiccation for years
Flight range is mostly < ½ km
Day biting mosquito (Early morning and
late afternoon)
Longevity - about 3 weeks
45. VECTOR BIONOMICS
Ambient temperature for breeding
16°C to 40°C
Indoor - rests in dark and cool places
Out door - shady places
High humidity & High temperature
enhance the vectorial capacity
46. FACTORS
FAVOURING AEDES
BREEDING
Population explosion
Urbanization
Faulty housing
Inadequate water supply
Wide use of non-biodegradable materials
Improper disposal of solid wastes
47. Components of Aedes Control
• Advocacy, social mobilization and legislation
• Colloboration within the health sector and
other sectors
• Integrated approach to vector control
• Evidence based decision making
• Capacity building
