This document discusses several arthropods of public health importance including mosquitoes, flies, fleas, lice, and bugs. It focuses on the four main genera of mosquitoes - Anopheles, Culex, Aedes, and Mansoniades. The life cycle of mosquitoes includes eggs, larva, pupa, and adult stages. Malaria is described as a life-threatening disease spread by the female Anopheles mosquito. Severe malaria can lead to complications like jaundice, seizures, organ failure, and even death. An integrated approach is needed for effective control of disease vectors.

Important group of Mosquitoes in India that spread diseases are four in number
1. Anopheles
2. Culex

4. Mansoniades

20. 4 differences among genera of adult mosquito
The important genera of mosquitoes that are of public health
importance are Anopheles, Aedes, and Culex.
The stages of a mosquito’s life cycle are as follows:
1. Eggs
2. Larva
3. Pupa
4. Adult mosquito

24. Egg - hatches when exposed to water.

25. Larva - (plural: larvae) "wriggler" lives
in water; molts several times

26. • Pupa - (plural: pupae)
"tumbler" does not
feed; stage just before
emerging as adult.
• Adult - flies short time
after emerging and
after its body parts have
hardened.

29. Malaria
 Mal’ aria means “bad air” (Originally thought to be caused by foul air)
 A life-threatening protozoan disease
 40% of the world’s population is at risk of getting the disease
 80% of population in India lives in low malaria endemic region
 80% of malaria burden in India is confined to 20% of population that live
in malaria endemic region in India

30. Female anopheles mosquito is the vector
o P. vivax
o P. Falciparum
The mosquito breeds in polluted water bodies,
brackish water, wells, cisterns, fountains, overhead tanks
etc.
 Mosquito bites during night time

33. Severe Malaria - consequences
-• Jaundice
-• Seizure
-• Bleeding problems
-• Liver failure
-• Kidney failure
-• Multi organ failure
-• “Death” also as a possible outcome
