To obtain quality cocoons, mounting the silkworm larvae at the appropriate time and good quality mountages are essential. Under Subtropical condition of North-West India rearers using mostly locally available mounting material viz., paddy/ wheat/ mustard straw, mango/ eucalyptus leaves etc. In the fifth instar on seventh and sixth day silkworms enter into maturation and stop feeding and begin to search place to build cocoons during spring and autumn season respectively. When larvae are in spinning stage, the room temperature 23-24 °C and 60-70 percent relative humidity along with good ventilation facility to be provided. However, for commercial exploitation rearers should take lot of care during mounting operations and wrong mounting, unsuitable mountages, adverse conditions during spinning and no/less mounting care affect all the economic parameters of the cocoon and in turn silk. Finally cocoons are to be harvested carefully and cleaned to eliminate bad cocoons otherwise it reduces the cost of cocoons.
