Abstract
Antheraea mylitta is a well known sericigenous insect of India of economicimportance. Unsynchronized and prolonged emergence of adult moth in thediapausing population of this insect affects the commercial egg production ingrainages to a great extent. The sex ratio (F: M) was found to be 1:1.4 in both wildand semi-domesticated populations. The frequency distribution of cocoon weightrevealed 92.62% of male population were confined to the cocoon weight range of8.1 to 12.5 g and 83.66% of female lied between 11.1 to 15.5 g in reared varietywhile, 78.2% male population ranged between 11.1 to 15.5 g and 87.3% of femalepopulation ranged between 15.1 to 19.0 g in wild variety. The mean cocoon weightof male was found to be 10.3 g and 13.5 g, whereas that in female was 14.1 g and16.1 g in reared and wild variety respectively. Wild variety was found to be superiorover reared variety in important cocoon characters, pupa weight and shell weight.The average shell weight per gram of pupal tissue formed was about 0.200g.
