• To ensure large-scale in-house independent evaluation of new silkworm hybrids/technologies in simulated conditions resembling that of the farmers.
• To assess the impact of these technologies on the target group.
• To work out the economics of the technologies under large scale rearing.
• To feed back the inventors with the merits and demerits of the technologies enabling them to make modifications before venturing into further evaluations outside the institute.
• To demonstrate the new technologies to the primary stakeholders.

The inventors of new technologies undertake small-scale evaluation at the laboratories. Results of further testing at different locations and at farmers level often do not match with the laboratory results. Conditions available for laboratory evaluation and further evaluations vary largely and so do the results. The gap in the performance of the technologies at the laboratory and field level is wide. To avoid prejudice in technology evaluation and validation, TVDC undertakes independent large-scale in-house evaluation of the silkworm hybrids and technologies and provides the inventors with the feedback with respect to their effectiveness, ease in adoption and economic viability. This enables the inventors to make necessary modifications in the technologies if need be.

Large-scale silkworm rearing in progress in TVDC rearing house

• Large-scale young stage silkworm rearing.
• Large-scale late stage silkworm rearing.
• Working out of Economics on rearing various new silkworm hybrids and other technologies.
• Modification of selected rearing technology to suit farmers' type large scale rearing.

1. Large-scale in-house evaluation of new bivoltine x bivoltine (bi-parental and tetra parental) silkworm hybrids.
2. Evaluation of new multi x bivoltine silkworm hybrids.
3. Evaluation of disease tolerant silkworm hybrids.
4. Evaluation of larval mounting and cocoon harvesting techniques.
5. Testing the efficacy of new sericulture disinfectants.

• Demonstration of large-scale sericulture practices.
• Feedback to technology developer/laboratory on the technologies tested.
