2. During culturing of silkworms, a few
unreelable cocoons are formed due to
genetic defects, diseases, pests, improper
rearing techniques, mounting and
transportation of cocoons resulting in
formation of defective cocoons which are
not suitable for reeling, hence sorted out
before marketing.
There are fourteen types of defective
cocoons - few being flimsy, immature
urinated fumigated, melted, spotted
double cocoons, double cocoons are
large, coarse, irregular spun by two
worms whose pupa is within the cocoon
shell where in the shell is made up of two
silk baves which are resulted due to
overcrowded mounting conditions,
mutations, high temperature and
humidity.
