PROBLEMS IN PRE-COCOON SEGMENT OF TASAR

1. Acute shortage of high quality eggs for silkworm rearing.

2. Outdoor rearing renders the crop highly prone to risks.

Pre-Cocoon in Traditional Sector:

1. Use of home-made layings (eggs) without eliminating disease.

2. Silkworm prone to damage by heavy rains.

3. Predators: bugs, lizards etc. inflict damage.

4. Poor sanitation : high disease incidence.

5. Cocoons sold to petty traders: poor price realization.

6. Average income Rs.2000 in 90 days.

Page 8: Life cycle of Tasar insect - Pradan · 1. Use of home-made layings (eggs) without eliminating disease. 2. Silkworm prone to damage by heavy rains. 3. Predators: bugs, lizards etc

Salient features of village level grainage:

• Owned and managed by individual entrepreneur.

• Established in rearing villages.

• Number of cycle per year : 1

• Expected production of DFLs : 4500

• Number of rearers to be catered: 12 – 18

Page 9: Life cycle of Tasar insect - Pradan · 1. Use of home-made layings (eggs) without eliminating disease. 2. Silkworm prone to damage by heavy rains. 3. Predators: bugs, lizards etc

Advantages of Village Level Private Grainages :

• Ensure timely supply of DFLs to the rearers.

• Reduce risk of crop failure.

• Cut cost of production of DFLs.

• Offer DFLs at affordable price to the rearers.

• Grainage owner organizes seed rearing.

• Rearers exert control over grainage owner to get good DFLs.

• Grainages promote concept of better services and quality.

Page 10: Life cycle of Tasar insect - Pradan · 1. Use of home-made layings (eggs) without eliminating disease. 2. Silkworm prone to damage by heavy rains. 3. Predators: bugs, lizards etc

• Sorted seed cocoons are tied to threads

• Bunches of cocoons hung in grainage

• Ambiance facilitates moth emergence

• Male and female moths couple

Process of DFL production in grainage

• Cocoons are dried briefly under sun

• Samples of the lot tested for disease

• Seed cocoons are sorted based on built

Page 11: Life cycle of Tasar insect - Pradan · 1. Use of home-made layings (eggs) without eliminating disease. 2. Silkworm prone to damage by heavy rains. 3. Predators: bugs, lizards etc

• Moths are manually decoupled

• Inseminated moths kept in egg laying boxes

• Moths lay eggs for 72 hours

• Grainage room thoroughly cleaned

•Walls and floors sprayed with Formalin

•Room allowed to dry up

Page 12: Life cycle of Tasar insect - Pradan · 1. Use of home-made layings (eggs) without eliminating disease. 2. Silkworm prone to damage by heavy rains. 3. Predators: bugs, lizards etc

•Female moths are checked for disease

• Graineur performs examination independently

•Eggs of healthy moths are retained

• Eggs are washed in soaps

• Soaked in Formalin

• Washed vigourously in flowing water

Page 13: Life cycle of Tasar insect - Pradan · 1. Use of home-made layings (eggs) without eliminating disease. 2. Silkworm prone to damage by heavy rains. 3. Predators: bugs, lizards etc

• Dried eggs are measured

• Packaged in small cotton bags

• Sold as Disease Free layings

• DFLs sold to the rearers from Grainage

• DFLs are sold through upfront payment
