Abstract: Through orthogone experiment,the opt imal medium was obtained for Bacil lus thur inginesisHBF-1 with insect icidal act ivity to scarabaeoidae larva. The medium contained 4value4% nitrogen B,1value2% starch,0value5% yeast power,0value04% KH2PO4,0value05% MgSO4valueFermentation was done with this medium in shakingflask. Result s show ed that the number of cells was 44 value 108cfu/ mL,and the produce of crystal was 2value1130 mg/mL. The mortality of A nomala corp ulenta larv a t reated with 50-fold of HBF- 1 fermented liquid was 78value3%on the 14th day of t reatment.
