摘要
以常见害虫粘虫为试验材料,用不同剂量超声波处理成虫,观察处理后期粘虫发育阶段的死亡率和羽化率变化情况。结果表明:随着超声波剂量的增大,粘虫死亡率呈明显上升趋势,羽化率有明显下降趋势,超声波作用生物效应显著,当作用时间为140 s时,成虫死亡率急剧升高,高于50%,当作用时间超过180 s时,几乎没有羽化的粘虫。
Taking the armyworms as test material,the paper studied mortality rate and eclosion rate of armyworm after different doses of ultrasound treatment.The results showed that the mortality rate increased and eclosion rate reduced with the increasing of ultrasonic dose.The results meant ultrasound had significant biological effect.When radiation duration reached 140 seconds,the mortality rate elevated quickly,above 50%.When radiation duration was over 180 seconds,there was no eclosion armyworm in the beaker.
