The institute’s oak tasar station. Oak tasar culture is practised in Manipur and effectively nowhere else in the institute’s remit, so this station carries that mandate on its own — breed development, rearing and grainage technology, and disease and pest control for Antheraea proylei and A. frithi.

Technologies developed here
| Technology | Year | Description |
|---|---|---|
| Establishment and popularisation of breed C27 | 2005 | Fecundity 155, hatching 65 %, larval duration 40 days, cocoon weight 7.06 g, shell weight 0.75 g, silk ratio 10.28, filament length 650 m — a 33 % improvement over control. |
| Raising and maintenance of block plantation of Quercus serrata | 2009-10 | Seedlings raised in polythene tubes for quick establishment and consistent quality leaf. Commercialised; under on-farm testing. |
| Use of PET bottles as uzi trap | 2000 | Waste bottle with a 3 cm hole and an inserted funnel, baited with sugarcane syrup and water at 3:7. Each trap covers 8–10 plants; 50 % improvement over control. |
| Sodium hypochlorite seed treatment against tiger band disease | 2000 | Egg surface disinfection in 0.2 % NaOCl for 30 minutes at 25–28 °C. Raises yield to 38–42 cocoons per dfl against 28–30 in control. |
