  5. 5. - an infectious tropical disease caused by the dengue virus, transmitted through a bite of a mosquito by the genus Aedes.
  6. 6. * THE DISEASE: A Viremia (presence of viruses in the bloodstream), resulting to febrile disease afflicting both children and adults, causing HEMORRHAGE and frequently DEATH, if left untreated.
  7. 7. * There is no commercially available vaccine. * Prevention and control are sought by reducing the habitat, controlling the number of mosquitoes, and limiting exposures to bites.
  8. 8. * The Primary Carrier of the Dengue Virus
  9. 9. *LIFE CYCLE (10-12 days) Eggs - Black and oval in shape - Laid singly above water surfaces of containers - Without float - Viability: 6 months to 1 year due to the presence of chorion Adult -Maxillary pulps shorter than probosis -Wings uniformly grayish black -Body and legs are black with distinctive white patches throughout -Thorax has markings 2 - 3 days 1 - 2 days Pupa -Non-feeding stage -Breeding trumpet is long, slender with narrow opening 6 - 8 days Larva: - Feeding stage - Breeds in clean and nonpolluted water - Short and stout siphon with one pair of hair tuft - Rests at an angle to the water surface
  10. 10. Vector Biology Aedes aegypti • • General characteristics Breeding habitat Resting habits • • • • Primary vector Involve in cases of epidemics Urbanized areas Lives indoors Aedes albopictus • • • • Secondary vector Maintains the virus in the environment Rural areas Lives outdoors *Vector Biology Confined to artificial containers indoors Rests in cool, dark corners of the house • • Prefers to breed outdoor, in natural containers Rests outdoors in clearings and vegetations
  11. 11. MORPHOLOGY Aedes aegypti Aedes albopictus Size - 3-4 mm - same Color - dark brown to black - same Thorax - lyre-shaped white marks or scales - single white marks Abdomen - with white scales - with white and dark marks Legs - with white marks *MORPHOLOGY - same
  12. 12. *VECTOR CHARACTERISTICS • BITING HABITS • “Daybiters” with two peaks of biting time: *1 to 2 hours after sunrise *1 to 2 hours before sunset • Only female mosquitoes bite because of the requirement of blood for oviposition • Males do not bite but feed on plant juices and nectar of flowers • Man is the preferred host but in his absence, lower vertebrates serve as substitute
  13. 13. *VECTOR CHARACTERISTICS • FLYING HABITS • Do not fly great distances • Farthest flight distance is within 200 to 400 meters radius from their breeding places • Adults found around 50 meters from the breeding sources
  14. 14. *VECTOR CHARACTERISTICS • BIONOMICS • At temperatures <10oC and >40oC, no developmental process takes place • Females mates with male only once • Blood meal takes place after 48 hours from emergence and after mating for egg production • Oviposition takes place about 2 to 5 days from blood engorgement • Prefers dark-colored background for oviposition • Lays egg 3 to 4 times in its lifetime –60 to 100 eggs per batch • Survival potential: 20-30 days
  15. 15. *CALCULATIONS 1x Mosquito lays 300 eggs in its lifespan of 21 days. ½ of those 300 eggs are female, that being 150 females. By the second generation in 42 days, 150 females should have laid another 150 females each which equates to 22,500 females. By the third generation, in 63 days we have an approximate total of 3,375,000 female mosquitoes from that one single larva.

  17. 17. THE TARGET:AEDES AEGYPTI LARVA *
  18. 18. *LARVA: MOST VULNERABLE STAGE IN ITS LIFE CYCLE •Rest at an angle to the water surface • Favorable temp.: 16 – 240C • Does not mature: 12 and 390C • Affected by chemical factors: * 1 – 2.3 % salt kills the larvae * 50% sea water kills larvae in 24 hrs. * Pure sea water kills larvae in 2- 4 hrs. * Soap causes drowning by preventing larvae to obtain air * Oil kills by asphyxiation by the film formed, cuts contact with the air

  23. 23. * *An ecologically safe preventive method used to interrupt the development of larva and pupa into adult mosquitoes.
  24. 24. * WHY LARVICIDE AS CHOICE OF CONTROL? THE AEDES MOSQUITO( CARRIER)IS MOST VULNERABLE IN THE LARVA STAGE WHEN THEY CAN BE LOCATED AND DESTROYED THE LARVICIDE CONTROL USING THE LARVICIDE TEMEPHOS IS A WORLD HEALTH ORGANIZATION RECOMMENDED METHOD LARVICIDE CONTROL IS APPROVED BY PHIL. DEPT. OF HEALTH SUCCESSFULLY USED IN COUNTRIES AS THAILAND AND INDIA
  25. 25. *WHAT IS TEMEPHOS? *Chemical Name: 0,0’(THIODI-4,1 PHENYLENE) BIS (O,0-DIMETHYLPHOSPHOROTHIOATE(56) *ORGANOPHOSPHATE Insecticide used as agricultural chemical for the control of LARVA of Mosquitos, Black Fly and Midge in orchards that is Non-Toxic to humans, mammals, birds and fish at recommended concentrations
  26. 26. * TOXICITY INFORMATION OF TEMEPHOS ASG1 * III. HEALTH HAZARD INFORMATION * OSHA STANDARD: None established * NIOSH RECOMMENDED LIMIT: None established * ACGIH RECOMMENDED LIMIT: TWA (Time Weighted Average) = 10 mg/m3; STEL (Short Term Exposure Limit) = 20 mg/m3 (deleted) (15c). TOXICOLOGY A. ACUTE TOXICITY * * * DERMAL: LD50 (24 hr) = 1300-1930 mg/kg (rabbit); >4000 mg/kg (rat)(62). * ORAL: * INHALATION: Acute inhalation (rat), >25 mg/m3 (56). LD50 = 8600 mg/kg (male rat); 13000 mg/kg (female rat) (62). LD50 = 8600 mg/kg (male rat, technical material) (56)
  27. 27. * CLINICAL TRIAL TOXICITY OF TEMEPHOS ASG1 * * B. SUBACUTE AND CHRONIC TOXICITY: In 2-yr feeding trials rats receiving 300 mg/kg diet showed no observable clinical effect. No toxic symptom was felt by humans receiving 256 mg/man for 5 d, or 64 mg/man for 28 d (62). * All animal species tested tolerated 10 mg/kg without clinical effect, and 1 mg/kg without effect on cholinesterase activity (15b). * Experience in the field for a period of more than one year has confirmed that 1 mg/l in drinking water is without effect (15b).
