外源JH对桃蚜种群消长及有翅率的影响
0
()
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。

Effect of JH Analogs on Alate Rate of Myzus persicaeSulzer and Population Dynamics
()
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
