Abstract

Tasar silkworm, Antheraea mylitta Drury distributed as various ecoraces, is a forest-grown, trivoltine, polyphagous insect feeding primarily on Terminalia arjuna and is commercially exploited in varied tropical zones of India. Its traditional rearing in forest plantations has many disadvantages like erratic climatic conditions, lack of supervision and easy access to pests and predators, leading to extremely low cocoon yield. As there is a need to evolve a new method of rearing to stabilize tasar production, consistent efforts are being made towards” indoor rearing”, from first instar to spinning. In the present investigation, a comparative analysis of the growth and biochemical aspects of indoor reared Tasar silkworm, Antheraea mylitta.D (Daba TV) is reported. It is observed that the protein content and Proteolytic activity in the fourth and fifth instars of indoor worms, reared under lower temperature and higher humidity than that of outdoor conditions, is higher than that of the outdoor worms in all the three crops.
