从灯蛾罹病死亡幼虫中分离筛选出苏云金杆菌ＢａｃｉｌｕｓｔｈｕｒｉｎｇｉｅｎｓｉｓＳＢ～１菌株（属血清型Ｈ３ａ３ｂ）；从引进的Ｂ．ｔ．菌种中筛选出ＳＢ～８菌侏（血清型Ｈ１）。该两株菌经发酵试验，生产性能良好，对抗药性强的台湾、泰国和深圳品系的小菜蛾毒力较高。田间试验表明杀虫效果好
Bacillus thuringiensis Bacillus thuringiensis SB-1 strain (serotype H3a3b) was isolated and screened from the dead larvae of moth larvae; t. Strain selected SB ~ 8 bacteria dwarf (serotype H1). The two strains of bacteria fermentation test, good performance, the resistance of the strong strains of Taiwan, Thailand and Shenzhen Plutella xylostella high toxicity. Field trials show that insecticidal effect is good
