The immense variability in the population of tropical tasar silkworm Antheraea mylitta D is an intriguing aspect to exploit heterosis effect in important quantitative and qualitative traits. In the present study, two reciprocal crosses with four combinations were prepared such as semi-domestic Daba (S-d) x Laria, Laria x Daba (S-d), Daba (wild) x Daba (S-d), Daba (S-d) x Daba (wild) and Parallely Daba (S-d) is maintained as control. The important grainage parameters such as coupling behavior, fecundity and emergence pattern of parent in captive condition was observed. The larval hatching and rearing (growth) performance of F1 larva was recorded, followed by assessment of cocoon traits. Erratic moth emergence was observed in the wild populations, while, in Daba (S-d) almost synchronized emergence and 100% self coupling observed although there was low coupling rate in the different crosses.
