Almost all of the rearers cleaned their rearing houses and equipment before rearing. The bed cleaning was done every instar of silkworms. They had done about 3.2 times in first and second instar silkworm and 5.3 times in 4-5th instar silkworm. The serious silkworm disease was grasserie. After mounting 2.4 days cocoon was harvesting.
