Abstract

The most important silkwonn available in the North-Eastern Region is the muga silkwonn Antheraea assama (Westwood). An experiment was conducted to study the effects of nutritional supplement of soluble protein aqueous extract from waste pupae on larval instars of Antherea assama in different concentrations and its impact on the larval growth and cocoon characters. The results revealed that the highest larval weight (71.9 gm.), weight of 10 mature larvae at Vth instar), single cocoon weight (6.73g), highest shell weight (0.83g), filament length of the yam (61Om), denier of silk thread (6.8) and shortest larval duration (24–28 days), lowest larval mortality were observed in 25% concentration pupae extract sprayed at vth instar larval stages of mugasilkwonn. It may be suggested that the protein extract of muga waste pupae may be utilised as a supplement on the muga food plant as a growth stimulater of the silkwonn, Antheraea assama ww, for better cocoon crop production and quality muga silk.
