Abstract
Taking two-instar Mamestra brassicae as experimental worm, the lit protection of uranin, activated carbon and melanin to MbNPV was defined by bioassay. The result indicated that 0.1 % melanin had the strongest photoprotection to MbNPV. Being exposure under the ultraviolet light for 20,40 and 60 minutes, the experimental worm＇s corrected mortality had a remarkably increase than other treatments.关键词
