During the experiment, different combinations of seed cocoons of Antheraea mylitta were grouped in three categories on the basis of weight of cocoons of male and female (higher, middle and lower) and total nine combinations were kept separately for emergence from cocoon. Different parameters like weight, length, girth of pupa, total fecundity, total unlaid eggs, coefficient of egg laying and number of hatched eggs were recorded. In comparison to all the combinations maximum fecundity was recorded in T₅ (middle female group and middle male group) 291. Unlaid eggs were statistically minimum in T₅ (11). Highest number of hatched eggs was found in T₅ (253). Maximum coefficient of egg laying was also observed in the T₅ (combination of middle female group and middle male group) 96.26 per cent. The correlation of cocoon parameters with cocoon weight were analyzed and it showed highly positive correlation with pupa weight (r=0.998); with cocoon length (r=0.834), with cocoon width (r=0.962) whereas negative correlation existed between cocoon weight and fecundity (r=-0.761); pupa weight and fecundity (r=-0.77). Hence, it can be concluded that T₅ (combination of middle female group and middle male group) was best combination for all parameters followed by T₄ (middle female group and higher male group).
