Summary
A total of eight cell lines were established from Helicoverpa armigera (3) and H. punctigera (5) embryos and ovaries. Cell lines were established and grown in TC100 and/or TC199-MK containing 10% fetal bovine serum. The serum-free medium ExCell™ 400 was also used, with and without 10% supplemental fetal bovine serum, but failed to generate cell lines from fat bodies, embryos, or ovarian tissues. Cell lines consisted of heterogenous cell types ranging from oval to fibroblast-like. This is the first report on the successful establishment of cell lines from H. punctigera. Cell lines from the two species were distinguishable from each other by DAF-PCR, and noticeable differences in minor bands were observed among cell lines from the same species. All of the established cell lines from both species were susceptible to HzSNPV but did not replicate more virus than that of a H. zea cell line (BCIRL-HZ-AM1-A11). However, an H. punctigera cell line (HP1) replicated AcMNPV to the highest titer (1.0×108 50% tissue culture infective dose/ml), and only one of the H. armigera cell lines (HA1) was susceptible to this virus.
