摘　　要：通过对邵东县16 a来稻秆潜蝇发生情况、田间调查和气象记载资料的整理分析,得出稻秆潜蝇的发生规律,即年度偶偏重发生、山冲田发生量大、青嫩稻田发生量大、6月下旬~7月上旬卵孵盛期雨日多的年份发生重、偏施或迟施氮肥的田发生量大和中稻田发生量大等;并制定了综合防治措施,即对稻秆潜蝇越冬场所除草施药,减少冬后虫源;增施磷、钾肥,控制幼虫为害;选用对口农药等,可以有效控制稻秆潜蝇的为害。Based on the organization and analysis of 16-year data on the occurrence situation of Chlorops oryzae Matsumura, filed investigation and meteorological records of Shaodong county, the occurrence regularities of Chlorops oryzae Matsumura were concluded as follows： the pest damage was occasionally serious in some years; it was in large quantities in fields located in flat ground of mountainous area and in those planting rice seedlings; in some years whose late June to early July, the period of abundant pest eggs, had many rainy days, the pest damage was serious; it was in large quantities in fields applied with too much potassium fertilizer or in those where potassium fertilizer was applied too late; and the fields planting medium rice had a large quantity of pests. Several comprehensive control measures were proposed, e.g. weeding and applying agricultural chemicals in the overwintering places of Chlorops oryzae Matsumura to reduce the pest source after the winter, increasing the application of phosphorus and potassium fertilizer and controlling the damage of larvae, and selecting correct agricultural chemicals to effectively control the damage of Chlorops oryzae Matsumura.
