Effort to enhance the bivoltine cocoon production to the tune of 231.31 lakhs of DFLs brushing under 12th five year plan (2013-17), CPP was implemented in 174 clusters in India, out of which 102 clusters in Southern India, among which 46 clusters in Karnataka state were implemented. Among the 45 clusters of Karnataka state Shapur cluster in Kolar District was identified for bivoltine sericulture development and increased bivoltine raw silk production. Subsequent upon the implementation of CPP during the period 2012-2017, 2.06 lakh DFLs were distributed among 996 farmers harvesting 59.00 kg cocoon/100 DFLs during 2013-14, 2.65 lakh DFLs among 1290 farmers with 60.72 kg during 2014-15,3.43 lakh DFLs among 1,343 farmers with 60.82 kg during 2015-16 period where as 4.73 lakh DFLs were distributed among 1,834 farmers with 70.42 kg cocoon/100 DFLs during 2016-17, respectively contributing 1.40MT of bivoltine raw silk production as against the benchmark DFLs brushing of 0.60 lakhs with 42.45 kg/100DFLs yield of the year 2011-12 under Shapur cluster. Further, the bivoltine farming community could also achieve in minimising defective cocoon from 7.98% (during 2010-11) to 1.15% by 2016-17 due to the intensive adoption of improved technical know-how. Moreover, the bivoltine sericultural development during 12thfive year plan (2013-17) has fetched the progressive average market rate from ` 262.65 to 432.53 by the adopted silkworm rearers under the cluster thereby improving the socio-economic conditions of the sericultural fraternity.
