Mulberry silkworms can be categorized into three different but connected groups or types. Mulberry silkworm. The major groups of silkworms fall under the univoltine ("uni-"=one, "voltine"=brood frequency) and bivoltine categories. For the classification of silkworm cocoons, in order to determine the category of each cocoon, the most difficult thing is how to extract the features of all kinds of cocoons as many as possible. Intensive and careful domestication over centuries has apparently deprived this commercial insect of the opportunity to acquire thermotolerance (Kumari ., 2011).This vulnerability is more pronounced in bivoltine breeds compared to multivoltine breeds. An adult silkworm has a wingspan of 40 to 50 mm (about 2 inches) and has a thick bristly body (the adult female is larger than the adult male). A wide range of hemocyte types exist in insects but a full definition of the different subclasses is not yet established. Silk reeling and testing manual.

In the Saturniids, an adult female may lay several hundred eggs during her brief lifetime, but perhaps only 1% will survive to their own adulthood. Univoltines These races have only one generation in a year. A pair of male and female fully-grown adult moth mate with each other, and the female subsequently lays eggs and dies. By feeding on the mulberry leaves, larvae takes pupa stage. Computer classification method for color of natural green silkworm cocoons India is the second largest silk producing country in the world after china.
