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