1·There were significant concentrations and timing differences in the hormesis induced by organophosphorus pesticides in microalgae.

两种农药对两种微藻产生毒物刺激效应的作用浓度存在差异。

2·Hormesis is that decreased risk of adverse effects would occur with increased dose levels when subjects are exposed to toxin at low levels.

毒物兴奋效应是指在较低药物剂量水平时，随着剂量水平的增加，受试者对药物的不良反应降低。

3·Ecological resurgence is attributed to pesticides weakening natural control systems whereas physiological resurgence refers to pesticide-induced stimulation of pest reproduction or hormesis.

前者的机制主要是药剂削弱了自然控制作用，后者主要是药剂引起害虫的毒物兴奋效应及补偿作用(刺激产卵)。
