The bivoltine silkworm hybrids of CSR2 x MG408 and CSR4 x MU852
were chosen for the present study to enhance the cocoon yield attributes and the
juvenile hormonal mimic was administered in a single dose at 48h, 72h and 96 h
of fifth instar at different concentrations such as 15μl, 25μl and 35μl and
parallel untreated control batches were maintained to compare the results.
