| 摘 要： | 通过对文登市23a历史资料的分析,明确了文登市二代玉米螟的种群变动规律,总体上二代玉米螟的发生程度和面积均呈明显的下降趋势。其中种植结构调整是导致防治面积下降的主要原因,化学防治面积的减少则充分保护利用了天敌资源,天敌的控制作用明显。

| Abstract: | Through the analysis of historical data for 23years of Wendeng city,the p opulation dynamics of the sec-ondary generations of Ostrinia palustralis populations were revealed.Overall,there was obviously a downward tren d in the occurrences and areas of the pest populations.The adjustment of cropping pattern was the main factor th at led to the decrements of area.And the red uction in the chemical control area was due to the preservation and applic a-tions of natural enemies.Natural en emies played significant roles in th e control of Ostrinia palustralis. |
