1. The enemy

2. The Aedes mosquito

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

7. Aedes Farms

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

10. Natural Aedes farms
• Tree holes
• Rock holes
• Leaf axils

11. Man made Aedes farms

12. Water storage tank or cisterns

13. Breeding in uncovered water tank

14. Generous mind to Aedes

16. Cement water container

17. Water containers

18. Water storage drum

19. Tyres every where

20. Perfect Home for the enemy?

21. Enemy home everywhere

22. Inviting the enemy

23. Concrete mixer

24. Floor mat- safe home for the enemy

25. Roof gutters

26. The forty two containers

27. Unwilling to dispose

28. Aedes in animal water container in
rural areas

29. All in one place

30. Mini homes for the enemy

31. Sweet home for the enemy

32. Opening the door for the enemy

33. Devil safe behind the God

34. What a devotion !!!

35. Coconut shells

36. Clean water for the enemy

37. Clean water for the enemy

40. Natural Aedes farms

41. Tree holes

42. Tree hole harbouring Aedes

43. Plantain leaf axil

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

48. Environmental control

49. Simpler Solutions

50. Problem to solution

51. Washing with bleaching powder
or ash and a brush

52. Discarding the water by
tilting the container

53. War waged by children

54. Trained eyes searching for the enemy

55. Accepts the problem: Thinks
deeply to find solution

56. Eureka

57. Source Reduction By NSS Students

58. Potable water sources
are
covered with cloth.

59. Used tyres collection campaign

60. Determined to win the war

61. Moved out for recycling/destruction

62. Young minds are trained to identify
the enemy

63. Demonstration of larval breeding
sources

64. School children as health messengers

65. Biological control
Larvivorous fish - Guppy, Gambusia
Biolarvicides -B. thrungiensis

66. Chemical control
Larvicide -Temephos 5 ml/10 liter
Adulticide-Pyrethrum extract
2%,Technical Malathion, Synthetic
pyrethroid (Deltamethrin and Cyfluthrin)

67. Fogging as an emergency operation
to knock down adult mosquitoes

68. Fogging into residences infested with the enemy

69. Fogging in the streets

70. Fogging in the public places

72. Together we can
bring change
