6. Medical Entomology General introduction to medical entomology

7. Objectives
1/ Recognize Arthropods that affect human Health. 2/ Define of Entomology and Medical Entomology. 3/ Give an example of Insect-borne diseases. 4/ Explain the association between Arthropods and human Health. 5/ Explain mode of Insect-borne diseases Transmission to Human.

8. Introduction to Medical Entomology
The science that deals to study the insects.
Medical Entomology:
Is a specialization that involves the study of those insects that are of medical importance.
Example:( mosquitoes, lice, house fly, tick, mites, bed bug, fleas, cockroaches……………etc)

9. Mosquitoes

10. House fly

11. Sand fly

12. Cockroach

13. Bed bug

14. Fleas

15. Mites

16. Ticks

17. Lice

18. The History of Entomology
In 1868 Fedtschenko discovered that the guinea worm (Dracunculus medinensis) underwent its early development in a Cyclops.
In 1877 Patrick Manson discovered that bancroftian filariasis (Wuchereria bancrofti) underwent development in mosquitoes.

21. What is the average amount of insects that are on the earth’s surface?
More than 750,000 species of insects have been identified.

24. Are all insects harmful to humans?
No. Only about 10,000 are harmful to humans.

25. Association between arthropods and human health
Insect and other arthropods can directly affect healthy mans by:
1- Transmitting diseases.
2- Annoyance to man by their bites.
3- Poisonous to man.
4- Severe irritations.

26. 3- Poisonous to man
Spider
scorpion

27. 4- Severe irritations
Bed bug

28. Methods of disease transmission
Vectors transmits pathogens or parasites from man to another by the following methods:
1- Mechanical transmission
For example: House flies carry the pathogens on their hairy legs, feet and bodies.
vector serves only as mechanical vector.

29. House fly

30. 2- Biological transmission
The pathogens have undergone multiplication and/or development within the insect.
In addition biological transmission including:
Transovarial transmission
Pathogens penetrate the ovaries of vector, result infected eggs.

31. Transstadial transmission:
The infection is acquired by one of the immature stages and passed to later immature stage or adults.
