ENT 606  INSECT BIOCHEMISTRY                                                                                 (2L+1P) III

Objective
To acquaint students with metabolic specializations in insects in relation to carbohydrates, lipids, amino acids and protein; biosynthesis and mode of action of  insect juvenile hormones and ecdysones.

Theory

UNIT I
Metabolic specializations in insects in relation to carbohydrates, lipids, amino acids and proteins; role of trehalose and glycogen in energy production.

UNIT II
Insect lipids and their metabolism during flight, diapause and reproduction; biochemistry of tyrosine, tryptophan and proline metabolism in insects.

UNIT III
Biosynthesis, mode of  action and metabolism of  insect juvenile hormones and ecdysones; pheromone biosynthesis and regulation of release; insect neuropeptides and special emphasis on PTTH, adipokinetic hormone, proctolin and bursicon; insect specific proteins.

Practicals
Estimation of  carbohydrates, lipids, amino acids and protein, JH, ecdysone etc. in insect haemolymph. To study pheromone biosynthesis and regulation of neuropeptides, adipokinetic hormone, proctolin and bursicon.
