| 摘 要： | 利用40株昆虫病原线虫共生菌菌株,以亚洲玉米螟和玉米小斑病菌作为供试昆虫和供试真菌,对其杀虫抑菌活性进行测定。结果表明,共生菌发酵液对两种病虫害均有一定的活性。其中菌株A24-2的杀虫抑菌活性最为明显,处理后120h对亚洲玉米螟的平均校正死亡率为44.25%,抑菌圈大小为15.00mm。

| Abstract: | Forty strains of symbiotic bacteria were isolated from entomopathogenic nematodes. Bioassay results showed that all strains had virulent activity to the first instar larvae of Ostrinia furnacalis and Bipolaris maydis to some extent, among which A24-2 strain was the best one. The average corrected mortalities to Ostrinia furnacalis was 44.25% and the antibiotic activities to Bipolaris maydis was 15.00 mm. |
