Explanation:
Cocoon Stifling
Dr.H.B.Mahesha, Yuvaraja’s College, University of Mysore, Mysuru, India.
Cocoons in their fresh condition with the pupae alive in them cannot be stored for
a long time as the living pupae are soon transformed into moths (i.e.,generally within
eight to ten days in a warm climate and ten to twenty days in a very cold climate), which
emerge from the cocoons by piercing the shell through one end. Cocoons from which
moths have emerged are called pierced cocoons. They are useless for reeling raw silk
because the continuity of the bave in them is broken. Reeling cocoons, therefore, have
to be subjected to a process of stifling with the object of killing the pupae inside without
interfering with the structure of the silk shell around it. Cocoons can be stifled by
several methods but the popular methods in reeling industry are sun drying, steam
stifling and hot air conditioning.
