ABSTRACT
By the breeding model of physics mutagenests (60Co,UV light) and re-strong in the body of insects, We obtained a Bt strain Bt99985 with high insecticidal activity. The shake flask and 40t tank fermentation tests showed that, this strain showed special activity against Spodoptera exjgua, Comparing with original Bt strain 93005, CK strain HD-1-580 and GC-91, the value of potency increased respectively by 429%, 655% and 114% in shake flask test. Comparing with GC-91, the value of potency increased by 180% in 40t tank fermentation test.
