Abstract
Tasar silkworm Antheraea mylitta D. is a polyphagous insect and is reared outdoor on the food plant like as Terminalia arjuna, Terminalia tomentosa, Shorea robusta.Productivity of cocoon in out door rearing is poor due to attack of number of pests,predators and diseases besides natural vagaries such as, wide fluctuatingtemperature, heavy rain and stormy wind etc. Attempts were made in the past toincrease the cocoon production by adopting various methods of indoor rearingparticularly for early instar worms and also by improving the rearing conditions.In the present study, indoor rearing was conducted in wooden tray supportedwith wooden rearing frames specially designed for young age and late agesilkworms. Trials were taken up to determine optimum number of feeds per dayfor indoor rearing of tasar silkworm and there effects on disease incidence. Threefeed per day resulted significantly lower mortality of worms due to diseases andother factors (65% and 70% during I and II crop respectively). Larval period wasalso recorded less under three feeding condition. Significant increase in commercialcharacters (cocoon weight and shell weight) was observed under three feedingscondition than other feeding treatments.
