Muga Silkworm Rearing Technology<\/strong><\/h1>\n

Muga silk worm is multivoltine and 5-6 crops are raised in a year out of which two commercial crops (Jethua: May- June and katia: October- November), two pre-seed crops (Jarua: December- January and Aherua: June- July) and two seed crops (Chotua: February- March and Bhodia: July- August. Usually pre-seed and seed crops encounter adverse climatic condition resulting in heavy loss during the early stages due to environmental rigours, disease incidence and infestation of pests and predators.<\/p>\n

Package of practices<\/h5>\n

Prune 15-20% of the plants at 6 feet height 4 months prior to rearing for early stage and 5 months prior to rearing for late stage worms. <\/p>\n\n\n\n\n\n\n\n\n\n

    \n
  • \"SILKS\"Apply 30 kg FYM and N:P:K @ 44:62:17 g\/plant after pruning. <\/li>\n
  • Dust bleaching powder and slaked lime mixture (1 : 9) @ 200 g\/m2 in the rearing plot atleast twice at an interval of 3-4 days before 8-10 days of brushing. <\/li>\n
  • Before 4 days of brushing, 0.01% Sodium Hypochlorite solution should be sprayed on the foliage of chawki rearing plot twice at an interval of 24 hours as disinfectant.<\/li>\n
  • Consider only microscopically examined disease free eggs and incubate at 26±1 °C and 85±5 % relative humidity. <\/li>\n
  • Use nylon net to protect the early stage worms from pests and predators. <\/li>\n
  • While fitting the nylon net attention should be given to keep sufficient space between the net and foliage for free aeration.<\/li>\n
  • Brush newly hatched worms on 90 days old foliage (120 days old in winter) under nylon net in between 5 to 7 AM on the opposite side of the sun during summer and towards sun during winter.<\/li>\n
  • While brushing, carrying capacity of the plant should be judged properly so that larvae may achieve 4th stage in the same tree without transfer.<\/li>\n
  • Consider only 1-3 days hatched worms for rearing. <\/li>\n
  • \"SILKS\"Brush 2-3 dfls per plant through visual observation of the carrying capacity of the plant. <\/li>\n
  • During extreme weather conditions i.e. hailstorm, heavy rain, whirl wind etc., brush worms indoor for 2-3 days in twigs kept in wet sand or in bottles containing water.
    \n\"SILKS\" <\/li>\n
  • Wrap the tree trunk with oil coated polythene sheet to prevent the worms from crawling down and predators from climbing up the trees.<\/li>\n
  • Avoid frequent handling of worms. <\/li>\n
  • Use disinfected Chaloni for transfer of worms. <\/li>\n
  • Transfer only the healthy and uniformly mounted worms to new plants. <\/li>\n
  • Overcrowding of larvae in the chaloni as well as in the new plants should be avoided.<\/li>\n
  • Periodical spray of sodium hypochlorite (0.01%) twice in each instar helps to reduce the possibility of outbreak of bacterial and viral diseases.<\/li>\n
  • Allow the worms to spin cocoons in bamboo box type mounts (capacity 1500 worms\/mount). <\/li>\n
  • \"SILKS\"Keep the mounts in semi dark, well aerated and rat proof room for better cocooning. <\/li>\n
  • Harvest cocoons only after completion of pupation (7th day in summer and 10th day in winter). <\/li>\n
  • Sort out good, flimsy, Uzi infested cocoons after harvesting<\/li>\n
  • Select well formed good cocoons for seed production as well as for reeling purpose.<\/li>\n<\/ul>\n
