A cell strain (IOZCAS-Spex-II-A) cloned from IOZCAS-Spex-II, a cell line established from the fat body of Spodoptera exigua (Lepidoptera: Noctuidae) larva, was characterized, and its capability to produce S. exigua nucleopolyhedrovirus was high with infection rate exceeding 90% compared with its parental cell line IOZCAS-Spex-II that scored only 50%. Growth curve of budded virus (BV) in the strain was analyzed and the titer of BV reached the highest of 3.7 x 10(4) pfu/mL by 96 h after inoculation. Concentration of occlusion bodies (OBs) produced by the cloned cell strain (IOZCAS-Spex-II-A) was 7.1 x 10(7) OBs/mL, while the parental cell line produced 2.4 x 10(7) OBs/mL. The average yield of the virus was 176 OBs/cell of IOZCAS-Spex-II-A compared with 211 OBs/cell that of the parental cell line. Significant differences were observed in virus production, growth characters, cell shape, between the parental cell line, and its clone. The cell lines (IOZCAS-Spex-II and IOZCAS-Spex-II-A) were also susceptible to Autographa californica multiple nucleopolyhedrovirus infection. In addition, they were characterized with regard to their growth rates and DNA amplification fingerprinting technique employing polymerase chain reaction.
