| 摘 要： | Helicoverpa armigera single nucleocapsid nucleopolyhedrovirus (HaSNPV) has been used as a commercial pesticide for the control of cotton bollworm. However, 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 and eliminates free radicals. Results in this research indicated that SOD-additive HaSNPV has a significantly higher efficacy to kill the bollworm on cotton leaves than HaSNPV alone. Therefore,SOD can be a promising enhancer for the HaSNPV pesticide.
