5. - an infectious
tropical disease caused
by the dengue virus,
transmitted through a
bite of a mosquito by
the genus Aedes.
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. * 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.
10. *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

Rests outdoors in

13. *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
14. *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
15. *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
16. *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.
19. *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

*An ecologically safe preventive
method used to interrupt the
development of larva and pupa

25. * 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
26. *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

HEALTH HAZARD INFORMATION
*
OSHA STANDARD: None established

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)
28. * 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).
