| 摘 要： | 2009～ 2011年对辽宁省受旱灾影响的北票市和受洪涝影响的铁岭市亚洲玉米螟发生危害情况进行调研,分析干旱和洪涝灾害对亚洲玉米螟种群动态的影响.结果表明,2009年6～9月持续干旱影响,受灾当年亚洲玉米螟种群数量大幅下降,第2年亚洲玉米螟心叶期危害较轻,但穗期危害较重,第3年种群数量恢复至较高水平；2010年7月下旬洪涝灾害发生条件下,亚洲玉米螟发生危害维持在较高水平,受灾年份越冬种群数量较大,但不能直接影响第2年亚洲玉米螟的发生.

| Abstract: | Studies on the occurrence and damage by Asian corn borer, Ostrinia furnacalis(Guenee) in the Beipiao affected by drought and Tieling city affected by flood were made during 2009-2011, to determine the influences of droughts and floods disasters on population dynamics of Asian corn borer. The results showed that from June to September 2009, the continuous drought made the population of Asian corn borer drop significantly, and made the damage ease at the whorl stage, however the damage be more serious at the panicle stage, and in the third year population recover to a higher level. In late July 2010, under the condition of flood disaster, the occurrence and damages by Asian corn borer maintain a higher level. In the affected year, the over wintering population was large, but it couldn't directly affect the happen of Asian corn borer in the next year. |
