| 摘要: |
| 通过外源JH对桃蚜种群消长及有翅率的影响研究得出，5种浓度的外源JH对桃蚜种群消长均有影响，5月5日的虫口数量与4月29日相比，J2、J3为负增长，且显著高于对照，即2％、1％浓度的外源JH桃蚜种群有抑制作用；5月5日的桃蚜成蚜有翅率J2－J5与对照相比，差异均极显著，即2％、1％、0．5％和0．25％浓度的外源JH对桃蚜成蚜有翅率有显著影响，5月5日的桃蚜成若蚜翅率，J1－J5与对照比较差异均极显著。 |

| Abstract: |
| The influences of JH analogs on the alate of Myzus persicae were studied.The results showed that five concentrations of JH analogs all had remarkable effects on the population dynamic:2% and 1% of JH analogs had restraint impacts on the population dynamic,and 2%,1%,0.5% and 0.25% of JH analogs had significant effects on the alate rate of Myzus persicae. |
| Key words: JH analogs,population of Myzus persicae Sulzer,alate rate of Myzus persicae |
