| 摘 要： | 2008-2009年,分别在辽宁省喀喇沁左翼蒙古族自治县和葫芦岛市连山区应用性诱剂监测了甜菜夜蛾全年发生动态,并对当地的主要作物的受害程度进行了调查。根据甜菜夜蛾越冬区划和越冬规律,结合当地越冬调查,明确了甜菜夜蛾在辽宁省田间不能越冬,其初始发生虫源性质属于外来迁飞虫源。轨迹分析结果表明,初始发生的甜菜夜蛾主要由我国黄海地区迁入。

| Abstract: | Beet armyworm adult populations were monitored using sex-pheromone-baited traps in Cazuo county and Huludao city of Liaoning Province in 2008 and 2009 respectively.The major crops damage caused by the beet armyworm was also investigated.The results indicated that the beet armyworm could not overwinter in Liaoning Province,the initial populations infesting might be immigrants from Huanghe-Rever and Huaihe-Rever region according to the trajectory analysis. |
