| 摘 要： | 初步研究了苏芸金杆菌(Bacillusthuringiensis,B.t)和家蚕核型多角体病毒(Bombyxmorinuclearpolyhedrosisvirus,BmNPV)对家蚕的联合致病作用。结果表明,BmNPV可增强B.t的毒力,增效作用显著;3.6×104、1.2×105mL-1B.t可增强BmNPV的毒力;与单独感染相比,B.t与BmNPV联合感染可缩短LT500.1～2.1d,加速家蚕死亡。

| Abstract: | Combination pathogenicity of Bacillus thuringiensis and Bombyx mori nuclear polyhedrosis virus to silkworms was investigated preliminarily, the results showed that BmNPV could enhance virulence of B.t remarkably, and so did 3 6×10 4 mL~-1 B.t and 1 2×10 5 mL~-1 B.t to BmNPV, and compared with single infection, combination infection of B.t and BmNPV could make silkworms die quickly, which’s showed by the decreased LT 50 ranging from 0 1 days to 2 1 days. |
