| 摘 要： | 采用毒力生物测定的方法,测定了600株从我国各地土壤和死虫等样品中分离的苏云金芽孢杆菌对东亚飞蝗的毒力.这些菌株几乎分布于已知的70个H血清型.在600株苏云金芽孢杆菌中,有560株(占93.4%)对东亚飞蝗无毒(死亡率小于20%),只有3株(占0.5%)对东亚飞蝗有较高毒性(死亡率大于70%).同时对筛选出的特异性菌株的杀虫活性进行了进一步研究.图2表2参8

| Abstract: | The toxic activities of 600 Bacillus thuringiensis strains isolated from soils and dead insects in China against Locusta migratoria manilensis were analyzed by using a virulent bioassay method. These isolates almost distributed over the known 70 H-serotypes(H1-H70). 560 strains (93.4% of the total) were nontoxic (mortality less than 20%) to L. migratoria manilensis, and only 3 strains (0.5%) had higher toxicity (mortality more than 70%). The activities of specific strains (H-13) against L. migratoria manilensis were studied also. Fig 2, Tab 2, Ref 8 |
