Cell lines from selected lepidopteran species were established for the overall purpose of use in baculovirus production. A total of 36 new cell lines from 10 lepidopteran species were generated, including cell lines from a pyralid, the European corn borer, Ostrinia nubilalis, a plutellid, the diamondback moth, Plutella xylostella, as well as eight noctuids: the black cutworm, Agrotis ipsilon, the celery looper, Anagrapha falcifera, the velvetbean caterpillar, Anticarsia gemmatalis, the corn earworm, Helicoverpa zea, the tobacco budworm, Heliothis virescens, the beet armyworm, Spodoptera exigua, the fall armyworm, Spodoptera frugiperda, and the cabbage looper, Trichoplusia ni. Tissues used for cell line establishment included fat bodies, ovaries, testes, or whole embryos/larvae/pupae. All the cell lines were subcultured numerous times, characterized by isoenzyme analysis and/or deoxyribonucleic acid amplification fingerprinting using polymerase chain reaction, and stored in liquid nitrogen. Many of the cell lines were adapted to grow in serum-free medium, with cell lines from A. ipsilon and H. virescens being adapted to suspension culture using shaker flasks. The potential use for these cell lines in baculovirus production is discussed.
