摘　　要：为绿色高效地防控亚洲玉米螟,于2011—2015年采用灯诱法在贵州省贵阳市花溪区、息烽县和安顺市平坝县进行高原山地环境下亚洲玉米螟成虫的灯诱种群发生动态研究。结果表明:贵州亚洲玉米螟成虫始见于4月,终见于9月中旬至10月中旬,高峰日在7月下旬至8月上旬。全年累计诱虫量最高663头,最低175头;高峰旬累计诱虫量占全年诱虫量的比例最高可达33.71%,最低为17.13%;灯下虫峰数量1~2个,主峰明显,多在7月下旬至8月上旬。贵州亚洲玉米螟的灯诱种群发生动态与田间的发生危害基本一致。In order to provide references for effectively controlling O. furnacalis, a trial of the population dynamics of light-trap collections of O. furnacalis from three counties of Huaxi, Xifeng and Pingba was conducted from 2011 to 2015. Results： Its first appearance was in April, and last appearance was from mid-September to mid-October, the peak day was from late July to early August. The annual number of light-trap collection was from 175 to 663, and the proportion of the peak ten days number was form 17.13% to 33.71%. There were 1-2 population peaks in one year, and only one main peak period, during late July to early August. The population dynamics of light-trap collection of O. furnacalis is almost consistent with occurrence situation ot corn borer in corn tields in Guizhou.
