研究结果表明，稻秆潜蝇自然种群死亡率最高在卵孵和初孵幼虫的侵入期，其次在化蛹至成虫羽化阶段。主要影响因子有气候、食料、肥水管理和天敌等。成虫产卵盛期至卵孵初期为防治适期，防治药剂有呋喃丹、甲基异柳磷、三唑磷、氧乐果等。 The results showed that the natural population mortality of M. lugens was the highest in the hatching period of egg hatch and newly hatched larvae, and secondly in pupae to adult eclosion stage. The main influencing factors are climate, foodstuff, fertilizer and water management and natural enemies. Adult spawning period to the early stage of egg hatch for the prevention and control of period, control agents carbofuran, methyl isofenphos, triazophos, omethoate and so on.
