VI. Theory
BLOCK 1: Anatomy of sericigenous insects
Unit 1:
Introduction, scope and importance
Different structures of the various internal systems. The scope of the
study for their application aspects and its importance for future
research work.
Unit 2:
Anatomical studies of various systems
Digestive, circulatory, respiratory, excretory, muscular, reproductive
and nervous systems (including central, visceral and peripheral) and
sense organs of larva, pupa and adult. Endocrine and exocrine glands
(including silkglands).
Unit 3:
Comparison of anatomical structures among various
sericigenous insects
Variation of anatomical structures in different life stages, viz., larva,
pupa and adult among different sericigenous insects mulberry, tasar,
eri and muga.
BLOCK 2: Physiology of different systems
Unit 1:
Introduction, scope and importance
Relation of structure to function and its application aspects.
Unit 2:
Physiology of different systems
Physiology of digestive, circulatory, respiratory, excretory, muscular,
reproductive, nervous system and endocrine and exocrine glandular
systems, Hormonal mechanism, enzymes, pheromones, nutritional role
of vitamins and other growth factors. Properties of haemolymph,
histology, nerve impulses, sensory physiology. Silkglands and silk
sysnthesis.

Unit 3:
Silkworm nutrition and synthetic/artificial diets
Qualitative and quantitative nutritional requirement of silkworms,
vitamins, carbohydrates, proteins and role of microbes in nutrition.
Preparation of artificial/synthetic diets for silkworms. Endocrinal
aspects of silk production.
