| 摘 要： | 为了减少环境污染，不杀伤天敌，使Ｂｔ制剂能在东北及内蒙古大兴安岭高寒地区应用，１９９５年，利用复配的Ｂｔ增效剂对二龄落叶松毛虫幼虫进行了试验，结果表明：在Ｂｔ制剂中加苏云金杆菌液体培养物上清液粉，可明显提高杀虫活性。如果将０．１ｇＢｔ＋０．０６４ｇ上清液粉与未加上清液粉的Ｂｔ制剂均稀释为１０００倍液，相比可提高防效１３％左右。用Ｂｔ制剂与灭幼脲３号混合防治落叶松毛虫二龄幼虫有明显的增效作用。１ｇＢ

| Abstract: | The synergist of Bt preparation was compounded for control of Dandrolimus superans in Northeast areas and Daxing'anling area of Inner Mongolia. 2nd instar larvae of Dendrolimus superans was tested for Bt preparation with different synergist. The results showed that adding upperly clear liquid powder, a liquid culture medium of Bacillus thuringiensis , to Bt preparation could improve insecticide activity obviously. The pest control rate was increased by about 13% when 0.064g liquid powder was added to 0.1g Bt preparation. By mixing with benzoylphenol urea -3(1g BtMP-342 mixed with 2ml benzoylphenol urea -3), the mortality of D. superans ' larvae was 100%, and the control rate increased by 20%. 1g BtMP-342 mixed with 0.5g miticide poison increased control rate by 14%. |
