Abstract: Sucrose,gluside,vitamin C and chintinase were used as synergists in the study.They could stimulate insects to eat and increase insecticidal activity of Bt in certain concentration.When gluside was mixed into Bt in the concentration of 0.2 g·L-1 under 15 ℃,20 ℃,and 25 ℃,the insecticidal activities were 39.9%,42.8%,29.4% respectively,higher than that of Bt used only.Moreover,compared with other additives it could stimulate insect to eat and increase insecticidal activity significantly. Besides, these synergists could increase the speed of killing larvas by Bt.
