| 摘 要： | 通过综合使用诱蛾器、探照灯、风场及降雨分析、扫描昆虫雷达观测、田间调查等监测手段及方法,探讨适用于吉林省三代粘虫的预测预报方法。结果表明,2015年度二代粘虫成虫数量较高,且有一定比例二代成虫滞留在当地并已产卵,气象条件不适宜于粘虫的向南回迁,扫描昆虫雷达直到7月29日始见粘虫向南聚集成层迁飞,田间调查发现较高密度的低龄期幼虫发生。2015年度三代粘虫在吉林省偏重发生,三代粘虫的实际发生情况验证了预报方式的有效性。

| Abstract: | The third-generation armyworm Mythimna separate(Walker) has posed a threat to corn production in Jilin province. Based on research methods of trap, pointing searchlight, weather analysis, scanning entomological radar and field investigation, this study was conducted to investigate the method for the armyworm prediction. The results showed that the number of adult was high, and part of their lay legs. Weather conditions were not appropriate for the southward migrated armyworm. There was a dense layer which formed by the southward migrated armyworm observed by scanning entomological radar until 29 July. Low-level larva was found in the fields. The third-generation armyworm caused severe damage in Jilin province this year. The actual situation proves the effectiveness of the prediction method. |
