Pupal ovaries of the wild oak silkworm Antheraea yamamai Guerin-Meneville were cultured in MGM-448 (Modified Grace Medium-448) medium containing 10% fetal bovine serum. After the primary culture was set up in 1988, a continuous cell line was obtained in 1991, designated as NISES-Anya-0611 (Anya-0611). The population doubling time was 54 hrs. and 19 min. at 96 passages and 88 hrs. and 29 min. at 387 passages. Spindle-shaped and spherical cells coexisted in the cell group. The cell line karyotype line was typical of lepidopteran cell lines, consisting of numerous small chromosomes. The cell line was distinguished from other lepidopteran cell lines by comparing malic enzyme, phosphoglucose isomerase, phosphoglucose mutase, and isocitric dehydrogenase isozyme patterns. The cell line was highly infected to the Antheraea yamamai nuclear polyhedrosis virus (Anya NPV). The luciferase gene of recombinant Bm NPV (BmNPVP6ETL) was able to express in the cell line, too, so that luciferase recombinant products were able to be detected in the cell body and in supernatant. The Anya NPV clone group was isolated on the cell seat using plaque purification.
