5. Life Cycle of Aedes Vector Egg 1.5 – 3 days Larva 6 – 8 days Pupa 1.5 – 3 days Adult 21 days

6. Characteristics of the Aedes Mosquit o 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 ”

7. 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

8. Vector Bionomics Indoor - rests in dark and cool places Out door - shady places Ambient temperature for breeding 16 °C to 40 °C High humidity and High temperature enhance the vectorial capacity
