| 摘 要： | 自28个昆虫病原线虫品系离体培养得到152株共生细菌菌株，筛选出高毒力菌株并提取杀虫粗提物，生物测定结果表明：线虫品系5的共生菌及其杀虫粗提物对亚洲玉米螟（Ostrinia furnacalis）幼虫有较高的胃毒活性，对未死虫的生长发育有明显的抑制作用。图2，表2，参9。

| Abstract: | 152 strains of symbiotic bacteria were isolated directly from 28 entomopathogenic nematode strains.The crude extract of the highly virulent strains was isolated. Bioassays results showed that the oral insecticidal activity of strain 5 was greater than others, which distinctly inhibited the growth of Ostrinia furnacalis larvae. |
