利用超氧化物歧化酶增加棉铃虫病毒的感染性

  • 棉铃虫单核衣壳核多角体病毒(Helicoverpa arm igera single nucleocapsid nucleopolyhedrovirus, HaSNPV)是棉铃虫的专一性病原,具有宿主特异 性高、不影响天敌、不污染环境、对人畜安全等优 点,在我国作为商品生物杀虫剂已有l0余年的历 史。

SOD Enhances Infectivity of Heficoverpa armigera Single Nucleocapsid Nucleopolyhedrovirus Against H.armigra Larvae

  • Abstract:Helicoverpa armigera single nucleocapsid nucleopolyhedrovirus(HaSNPV)has been used as a com m ercial pesticide for the control of cotton bollworm .H owever, some kinds of phenolase (particularly peroxidase)secreted by cotton glands,which generate free radicals,diminish the infectivity of baculoviruses significantly on cotton leaves.Superoxide dismutase(SOD)acts on the polyphenolic substance an d eliminates free radicals.Results in this research indicated that SOD—additive HaSNPV has a signi fican tly higher efi cacy to kill the bollworm on cotton leaves than HaSNPV alone.Therefore, SOD can be a promi sing enhan cer for the HaSNPV pesticide.
