一、引言 昆虫病毒,由于其宿主特异性高,既不直接损害天敌,也不干扰作物生理,可以认为是一类不破坏环境的害虫防治因素;在害虫综合治理中正逐渐引起人们的注意。 从发病快、生产易、宿主域狭等方面考虑,一般认为杆状病毒是较理想的生物杀虫剂。但为什么至今生产应用的还不多呢?这里固然有经济的问题(国外对优良病毒毒株无专利、开发投资大,使用次数与需要量少等)、技术的问题(生产技术与应用技术的 I. INTRODUCTION Insect virus, because of its high host specificity, neither directly damages natural enemies nor interfere with crop physiology can be regarded as a kind of non-destructive environmental pest control factor. It is gradually attracting people’s attention in pest comprehensive management. From the fast onset, easy production, the host domain narrow consideration, the baculovirus is generally considered to be more ideal bio-pesticides. But why is there not much production and application so far? Although there are economic problems here (no foreign patent for excellent virus strains, large investment in development, the use of less and less requirements, etc.), technical problems (production technology and application of technology
