| 摘 要： | 为研究苏云金芽孢杆菌(Bt)防治贮烟害虫的可行性,从全国7个主要卷烟厂的不同贮烟仓库中采集到不同类型的样品521份,采用醋酸钠抑制选择法从其中的225份样品中分离获得Bt952株,其分布率为100%,检出率为43.19%,用其中600株的发酵液对2~3龄烟草甲幼虫进行了初步毒力测定。结果表明,有18株分离株对烟草甲幼虫具有较高的生物活性,药后9d烟草甲幼虫的校正死亡率均达73%以上。 |

| Abstract: | For investigating the feasibility of stored tobacco pest control with Bt,952 Bt strains were isolated with sodium acetate restraining from 225 samples among 521 samples collected from different(tobacco) warehouses of 7 major cigarette factories.The distribution rate of Bt was 100% and the(detectable) rate of Bt was 43.19%.The virulence against 2-3 instar larvas was determined preliminarily with(fermented) solutions of 600 isolated strains.The result showed that there were 18 strains showing higher toxicity,the corrected mortality of the larva was above 73% in 9 days after applying. |
| Keywords: | Tobacco warehouse Bacillus thuringiensis(Bt) Lasioderma serricorne Insecticidal activity |
