五、发展微生物杀虫剂的技术参数1、生产可实行性(1)一般说明昆虫病原可以用发酵方法(体外方法)或活虫感染方法(体内方法)进行生产。发酵法(深层的或表面的)已被用于兼性昆虫病原的生产;而对于专性寄生的昆虫病原则只有用活体内的方法生产。这两种方法都已成功地应用于商业产品的生产。例如,苏云金杆菌和森田芽孢杆菌都来用深层发酵进行 Fifth, the development of microbial pesticide technical parameters 1, the production can be implemented (1) General Description Entomopathogenic bacteria can be used fermentation methods (in vitro methods) or live insect infection method (in vivo method) for production. Fermentation (deep or superficial) has been used for the production of facultative entomopathogenic bacteria; whereas for obligate parasitic entomopathies only in vivo methods have been developed. Both of these approaches have been successfully applied to the production of commercial products. For example, both Bacillus thuringiensis and Bacillus subtilis are used for deep fermentation
