PRIMARY CULTURES OF THE CELLS FROM OVARIES OF THE CABBAGE ARMYWORM, MAMESTRA BRASSICAE L. (Lepidoptera: Noctuidae)

Ovaries from post-diapause pupae of the cabbage armyworm, Mamestra brassicae, were cultured. Three types of cells migrated from the explants. Epithelial-like cells formed confluent monolayers, and fibroblast-like cells formed cellular networks. Isolated cells were distributed around the explants. Epithelial-like cells and isolated cells were common, and fibroblast-like cells were rather rare. The migrated cells survived for more than 6 months, although mitoses were rarely observed.
