Unit II: Medical importance of sandfly – borne diseases: Kala azar – prevalence and distribution –Present status – recent advances in managing kala azar. Cutaneous leishmaniasis: prevalence and distribution. Chandipura virus: prevalence and distribution.
 

Unit III: Muscoid flies (filth breeding flies): Classification - Habitat – Habit – Distribution - Morphology of mouth parts and reproductive system – Biology of immature – Behaviour of adults; feeding, resting and oviposition behaviour. Impact of sanitation on fly abundance.
 

Unit IV: Muscoid flies (Myiasis flies): Morphology of mouth parts and reproductive system – Mode of infection of myiasis maggots – Accidental, facultative and obligatory myiasis – Characteristic features of myiasis flies - Medical importance of myiasis in human.
 

Unit V: Black flies: Classification of family Simulidae - Habitat – Habit – Distribution -Morphology of mouth parts and reproductive system – Biology of immature and adult – Disease transmission cycle.

Practicals:

  • Identification of some of the important species under the genus Phlebotomus, Musca, Chrysomyia, Glossina, Simulium etc.

  • Observing and understanding the characteristic features of the life stages of the genus Phlebotomus, Musca, Chrysomyia, Simulium etc. with live or preserved specimens.

  • Techniques involved in rearing some of the medically important insects.
