摘要
根据历年在湖南衡阳地区对三化螟发生原因的有关数据分析，结果显示出以双季连作为主的单、双混栽，迟熟晚粳品种大面积连年种植，改连晚田冬闲冬泡为冬种有利于安全越冬是促使三化螟种群数量上升并连年大发生的主要因素。
Based on the relative data over the years in Hengyang Prefecture, Hunan Province, causes for the occurrence of the yellow rice borer, Tryporyza incertulas (Walker) were analysed. Results showed that key factors caused the rise and outbreak of the population of this pest insect were : (1) the mixed planting of the early rice and late rice, (2) successive planting of the late ripening japonica rice in the large area, and (3) the fallow paddy field in winter change to the winter planting.
