| 摘 要： | 制备出苏云金芽孢杆菌（B．t．）β-环糊精包合物，并对包合物进行了差热分析，证明B．t．原粉被β-环糊精包合。室内生物活性测定结果表明，当B．t．原粉与β-环糊精质量比为0．5：2时，包合物对棉铃虫2龄幼虫的杀虫活性最高，确定包合物中B．t．原粉与肛环糊精的最佳质量比为0．5：2。盆栽药效试验结果表明，当B．t．原粉制成环糊精包合物后，与B．t．原粉和B．t．制剂相比，对小菜蛾的防效明显提高。药剂处理后1、3、7d，B．t．环糊精包合物对小菜蛾的防效分别为41．67％、61．54％和60．00％，而B．t．原粉和制剂的防效分别为23．61％、38．46％、32．00％和31．94％、52．31％、46．00％。

| Abstract: | Bacillus thuringiensi(B.t.) beta-cyclodextrin inclusion was prepared. Differential thermal analysis indicatedformulation of inclusion complex. The results of bioassay in the laboratory showed the optimum ratio of B.t. toinclusion was 0.5:2, when B.t. beta-cyclodextrin inclusion had the highest bioactivity to Heliothis armigera. On theother hand, the pot trials with B.t. beta-cyclodextrin inclusion was carried out. Contrasted with B.t. and B.t. formulation,B.t. beta-cyclodextrin inclusion had the highest control effect to Plutella xylostella L. The control effect of B.t. beta-cyclodextrin inclusion was 41.67%, 61.54% and 60.00%, while that of B.t. and B.t. formulation was 23.61%, 38.46%,32.00%, 31.94%, 52.31%, 46.00% respectively, after 1, 3, 7 d. |
