2. Vector-borne Diseases
A vector-borne disease is one in which the pathogenic
microorganism is transmitted from an infected
individual to another individual by an arthropod or other
agent.
The transmission depends upon the three different
living organisms:
The pathologic agent, either a virus, protozoa or
bacteria.
The vector - Mosquito
Intermediary hosts- Human

3. THREE TYPE OF VECTOR
AEDES : Vector of Dengue and Chikungunya
ANOPHELES : Vector of Malaria
CULEX : Vector of Japanese Encephalitis
Aedes Anopheles Culex

4. Different stages of larvae

5. LIFE CYCLE OF MOSQUITO
 Mosquitoes generally lay 100-150 eggs at
a time
 Eggs are very hardy; they stick to the
walls of a container and can survive
drying out for up to 8 months.
 Larvae emerge from mosquito eggs when
water level rises to cover the eggs.
 Larvae feed on microorganisms in the
water. After molting three times, the larva
becomes a pupa.
 Pupae will develop until the body of the
newly formed.
 After adult mosquitoes emerge: male
mosquitoes feed on nectar from flowers
and female mosquitoes feed on humans
and animals for blood to produce eggs.

7. Mosquito Pupa
 Mosquito pupae, commonly called "tumblers", must live in water
from 1 to 4 days, depending upon species and temperature.
 The pupal stage is a resting, non-feeding stage. Pupae will develop
until the body of the newly formed adult flying mosquito
emerges from the pupal skin and leaves the water.
 This is the time the mosquito turns into an adult. It takes about two
days before the adult is fully developed.

16. Suggestion
1- Source reduction

17. 2.Personal Prophylatic Measures
 Use of mosquito repellent creams, liquids,
coils, mats etc.
 Screening of the houses with wire mesh
 Use of bednets treated with insecticide
 Wearing clothes that cover maximum surface
area of the body.
