多点小面积和大面积防治试验证明，由室内及林间增殖的ＮＰＶ配制病毒制剂防治柳毒蛾幼虫是有效的。一旦将病毒引入林内，即可引起流行病发生并导致柳毒蛾密度锐减。其喷洒剂量应在６．０×１０１１～７．５×１０１１ＰＩＢ／ｈｍ２，最高不超过１．５×１０１２ＰＩＢ／ｈｍ２。防治适期应在３～４龄幼虫占８０％左右时为宜，也可提前在２～３龄幼虫占８５％左右时进行。喷洒时间在１６∶００以后为好
Multi-point small area and large-scale prevention and control tests have proved that it is effective to control the larvae of volcanic larva by the indoor and inter-proliferation NPV. Once the virus is introduced into the forest, epidemics can be caused and the density of the venomous moth can be drastically reduced. The spray dose should be 6.0 × 1011 ~ 7.5 × 1011PIB / hm2, the maximum does not exceed 1.5 × 1012PIB / hm2. Preventative period should be 3 ~ 4 instar larvae accounted for about 80% is appropriate, but also in advance 2 ~ 3 instar larvae accounted for about 85%. Spraying time after 16:00 is good
