  • Established cell lines from
    Patent number: 7718427
    Abstract: The present invention relates to Lymantria xylina cell lines established from pupal tissues of L. xylina Swinhoe, including NTU-LY-1, NTU-LY-2, NTU-LY-3, and NTU-LY-4. These four cell lines were confirmed to be newly established cell lines derived from L. xylina by random amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR) and isozyme analysis. The genotypes and characteristics of the abovementioned cell lines are totally different from other insect cell lines. In addition, these four L. xylina cell lines are susceptible to insect baculovirus of L. xylina multiple nucleopolyhedrovirus (LyxyMNPV), LdMNPV-like virus, PenuMNPV, as well as microsporidia of Nosema sp. (isolated from Eurema blanda) and N. bombycis and the like. Therefore the invention can be applied in multiplication of the abovementioned insect-pathogenic microorganisms to produce biopesticides in pest control.
