A new cell line named RIRI-PaDe, developed from the neonate larvae of Papilio demoleus Linnaeus, was established in modified Grace's medium supplemented with 20% fetal bovine serum. The cell line was incubated at 28°C and consisted of attached round and short spindle-like cells. The population doubling time was 55 h. The chromosome numbers varied widely from 24 to 136 with a mode of 59 at the 71st passage. Comparison of mitochondrial cytochrome c oxidase subunit I gene of the cell line and neonate larvae confirmed that the cell line was of P. demoleus origin. This cell line was susceptible to the Autographa californica multicapsid nucleopolyhedrovirus and Apocheima cinerarius nucleopolyhedrovirus.
