| 摘 要： | 研究了Snf907真菌代谢物原液及不同稀释液对甘薯茎线虫活性及运动行为的影响。结果表明,在1,5,10,20,50倍稀释液浓度下二龄幼虫的校正死亡率分别是87.06%,78.73%,41.21%,24.37%,14.00%,均与无菌水对照差异显著;其不同浓度的代谢物对甘薯茎线虫的行为影响不同,随着浓度的增大和时间的延长,对甘薯茎线虫活动频率的抑制也增强。 |
| 关 键 词： | 真菌代谢物 甘薯茎线虫 校正死亡率 运动行为 |

| Abstract: | The effect of Snf907 fungus metabolites on the juvenile of Ditylenchus destructor were investigated.The corrected mortality rate of juveniles were 87.06%,78.73%,41.21%,24.37%,and 14.00%,respectively,at 1×,5×,10×,20× and 50× dilution.The difference between these treatments and water control were significant.The different dilution of fungus had different effects on the behavior of D.destructor.The restrain on moving frequency of D.destructor was enhanced with the increased concentration and extended time. |
| Keywords: | Fungus metabolites Ditylenchus destructor Corrected mortality Behavior |
