2. MOSQUITO BORNE DISEASES Type of mosquito Diseases transmitted Anopheles Malaria, Filaria (not in India) Culex Bancroftian filarial, JE, West Nile Fever, Viral arthritis Aedes Yellow fever, Dengue, DHF/ DSS, Chikungunya fever, filarial (not in India) Mansonides Brugian filarial, Chikungunya fever

5. Life cycle of Mosquito It is an example of complete metamorphosis. It consists of four stages of egg, larva, pupa and adult . Life cycle is completed in 10-12 days . Water is necessary for completion of Life cycle.  

6. Life-cycle Mosquito Eggs 2. Larva *”wriggler” stage 1-2 days 3. Pupa Non-feeding stage Adult develops “tumbler” 4. Adult Blood meal to mature 5-7 days 2-3 days

AEDES TRANSMITS 1.Yellow fever 2.Dengue fever 3.Dengue haemorrhagic fever 4 Dengue shock syndrome 5.Chickungunya fever 6.Chickungunya hemorrhagic fever 7.Rift valley fever 8.Filaria(not in India) IMPORTANT SPECIES 1 A. aegypti 2 A. albopictus 3 A. vittatus 4 A. polinensiensis 5 A. samounus 6 A. poesilius

8. Mosquito Control measures : Control of mosquitoes provides an effective way of controlling mosquito borne diseases. Control measures include various methods

9. Biological control Legislative control Physical control Chemical control Environmenal control

10. Methods of Vector control . 1. Anti-larval measures (a) Environmental control (b) Chemical control (c) Biological control 2. Anti-adult measures (a) Residual sprays (b) Space sprays (c) Genetic control 3. Protection against mosquito bites (a) Mosquito net (b) Screening (c) Repellents

11. Physical control Protection against mosquito bites (a) Mosquito net (b) Screening (c) Repellents

12. Mosquito Protection

13. Chemical control

14. Biological control

15. ENVIRONMENTAL MODIFICATION (1) Drainage : urban or rural drainage of infested water with vectors. E.g. sullage and rain water accumulated agricultural and watershed drainage (2) Filling : by filling , topography alteration (3) Land leveling and transformation of impounding margins. (4) Velocity alteration

16. ENVIRONMENTAL MANIPULATION They are as follows; (1) Stream flushing (2) Regulation of water level in reservoirs (3) Vegetation removal etc.

17. Aerosols, Mists and Fogs Ultra-low-volume applications Residual house-spraying

18. GENETIC CONTROL Sterile male technique Cytoplasmic incompatibility Chromosomal translocation Sex distortion Gene replacement There use still in the research phase

19. Integrated Vector Control Making use of two or more than two of the above methods. Advantages Cost effective, Minimizes Pollution Reduces resistence Best long term measures
