应用病毒防治森林害虫,因有公害小,不伤害天敌,效果好及具有持续效果等优点,而日益引起人们的重视。国内、外在这方面均做了大量的研究工作,并取得很好的防治效果。随着应用病毒防治害虫的发展,各国亦很重视用飞机喷洒病毒制剂防治森林害虫,但在防治效果方面有较大的差异。法国,罗马尼亚工作组曾用1×10~(13)PIB/公顷,以航空微滴喷雾(舞毒蛾NPV),经25～30天观察,其死亡率达59.6～66.8％(Mihalache G.1938)。据Iniae M.(1978)报导,用7.6×10~(11)PIB/公顷的NPV悬液喷洒,经25～30天观察,舞毒蛾大量死
Application of the virus in the prevention and control of forest pests, due to small public nuisance, does not harm natural enemies, the effect is good and has the advantage of sustained effects, and more and more aroused people’s attention. Both at home and abroad, a great deal of research work has been done in this area and very good prevention and control effects have been achieved. With the development of virus prevention and control pests, various countries attach great importance to the use of aircraft spraying virus preparations to prevent and control forest pests, but there are great differences in prevention and treatment effects. The French and Romanian working groups used aerosol droplets (Gypsy moth NPV) at 1 × 10 ~ (13) PIB / ha to observe a mortality rate of 59.6-66.8% after 25-30 days (Mihalache G.1938) . According to Iniae M. (1978), spraying with a suspension of NPV at a concentration of 7.6 × 10 11 PIB per hectare, after 25 to 30 days of observation, Gypsy moths died in large numbers
