摘　　要：棉铃虫单核衣壳核多角体病毒(Helicoverpa armigera 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10余年的历史.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.
