摘要
1998～1999年的试验结果表明:稻秆潜蝇在四川水稻上一年发生一代,生活史长达140d,麦田及沟边的看麦娘是其的主要越冬寄主,稻秆潜蝇翻颚茧蜂是越冬蛹的主要寄生性天敌,越冬蛹在次年水稻秧苗一叶一心至二叶一心时开始羽化并产卵,此期为防治的关键时期。
The experiments in Anxian and Yaan from 1998～1999 show: Chlorops oryzae Matsumura occurs in 1 generation per year in Sichuan rice paddy and it's life cycle is about 140 days. Alopecurus atqualis Sobol is main overwinter host and Dacnusa sp. is main parasitoid natural enemy of overwinter pupas. The eclosion and ovipositing of overwinter pupas are about in the period of 1～2 rice leaves with 1 tiller, and this period is the key control period.
