Antheraea mylitta cytoplasmic polyhedrosis virus (AmCPV), a cypovirus of Reoviridae family, infects Indian non-mulberry silkworm, Antheraea mylitta, and contains 11 segmented double stranded RNA (S1-S11) in its genome. The commercially important tropical tasar silk insect, Antheraea mylitta Drury (Lepidoptera: Saturniidae) is having 44 ecoraces distributed along central India (12-31°N latitude and 72-96°E longitude) with varied phenotypic, physiological and behavioral characters. The most notable feature of the moth is its large, purplish eyespots on its two hindwings.The eyespots give it its name – from the Greek myth of the cyclops Polyphemus. A silkworm's total life cycle has a range of 7-8 weeks. The N-terminal sequencing of ten amino acids (NH 2-SVVHPPHHEV-COOH) showed similarity with Antheraea pernyi arylphorin. It is a tan-colored moth, with an average wingspan of 15 cm (6 in). Adult Butterfly. The Indian tasar silkworm, Antheraea mylitta is a natural fauna of tropical India. Further the life cycle of insect ranged from 65 to 70 days. Noun 1. It feeds on primary food plants, viz. Abstract. Two cDNA libraries, one from the whole bodies of one-day-old larvae and the other from the silkglands of fifth instar larvae, were constructed and sequenced. The life cycle of A. mylitta starts with egg followed by larval and pupal stages and finally, the moth stage. The duration of pupal phase (from 0-day pupa to adult eclosion) in the BV group is more (200–210 days) than that of the TV group, which is 150–160 days. Antheraea mylitta arylphorin protein was extracted from the silk gland of fifth instar larvae and purified by ammonium sulphate precipitation, ion-exchange, and gel filtration chromatography.
