【摘要】 苏云金杆菌(BallusthuringiensisBt)与斜纹夜蛾核型多角体病毒(PlNPV)复配后,可以提高防治效果并能扩大杀虫谱。但苏云金杆菌菌株的毒力活性与其发酵工艺产品的不同而异,不同工艺产品与病毒复配后,其毒力的增效作用也有所不同。本实验是用不同制剂感染斜纹夜蛾初孵幼虫,进行单一、复配制剂药效的对比试验,从而筛选出苏云金杆菌复配中的最佳工艺产品——自制的液体发酵Bt产品。更多还原

【Abstract】 <Abstrcat> When Ballus thuringiensis (Bt) mixes together with Prodenia litura nucleopolyhedrovirus (PINPV), the newly bio-pesticide can improve its precaution effect and kill more species of pests. However, its toxicity intensity and activity, which relate to its different technical product of fermentation, vary greatly. Also, the diff effectiveness of the toxicity changes according to diverse mixtures of technical products and the viruses. In our experiments, we used different preparations to infect the first stage larvae of Prodenia litura, and compared the toxicity effectiveness between a single ingredient and mixed ingredients. Consequently, we have made the most effective technical product from these recipes.更多还原
