摘　　要：记载了亚洲玉米螟Ｏｓｔｒｉｎｉａｆｕｒｎａｃａｌｉｓ（Ｇｕｅｎｅｅ）在永德地区１９９５年的季节变化情况。利用黑光灯和性诱剂诱捕成虫，利用田间调查得到幼期数据。报道了亚洲玉米螟各虫态发生与有效积温的关系。测定单条正弦曲线下的面积获得田间有效积温，而正弦曲线在１０．３５℃和３２．０℃范围内拟合日最低温和日最高温而得。亚洲玉米螟各虫态的每周调查数据显示其发育进展符合在室内测定的各虫态对积温的要求。建立了成虫累积捕获量正规偏差值与有效积温对数值（ｌｏｇ（１０））的回归公式。seasonal development of the Asian corn borer, Ostrinia furnacalis (Guenee), was investigated in Yongde County in 1995. Adult ACB moth flight was observed using blacklight and pheromone traps and immature stages were observed by field investigation. The relationship between temperature accumulation and emergence of each life stage of ACB was proposed. The accumulation(degree days)was obtained by measuring the area under a single sine curve fitted to the day's minimum and maximum air temperatures within 10 35℃ and 32℃. Weekly catches of each life stage of ACB were fitted to the expected cumulative degree days determined in laboratory. Equations resulting from regressions of the pobit of cumulative percentage of adult captures on log(10)of cumulative degree-days were calculated.
