Sericulture Caterpillar-Cocoon Sericulture is that the cultivation of cocoons for his or her filaments. the most effective raw silk is obtained from the species of lepidopteron known as bombycid moth. Breeding of silkworm happens once in an exceedingly year however underneath scientific conditions, they'll be hatched thrice a year. the feminine lepidopteron lays around 350 to four hundred eggs and also the moths die shortly when. As they're subject to hereditary infection, the eggs from infected moths square measure destroyed which ends up into production of fine silk. Larvae of concerning 3mm square measure hatched from the eggs. For concerning twenty to thirty days, rigorously nurtured and are fed 5 times on a daily basis on cut mulberry leaves. Within the meanwhile, the larvae amendment their skin for fourfold and square measure fashioned into caterpillar of concerning nine cm long. currently they're able to spin cocoon that racks, clusters of twigs or straw square measure provided.
The caterpillars have little openings underneath their jaws known as spinnerets through that they secret a super molecule like substance. This substance solidifies once it comes in-tuned with air and also the filament therefore fashioned is spun round the silkworm within the figure resembling the digit eight. In 3 days the cocoon gets completed that is a couple of peanut shell's size. The filament is command along by sericin or silk gum. The lifetime of the worm is over by the method of 'staving' or 'stifling' within which the cocoons square measure heated. a number of the cocoons square measure preserved in order that the insect or pupa within them turn out to be moths for more breeding.
