摘要/Abstract

摘要： 文章通过两年两地对草地螟越冬基数、化蛹羽化进度调查以及对成虫动态的系统观察，结果表明，2008年鄂尔多斯市、乌兰察布市部分旗县草地螟越冬幼虫分别范围广、虫茧基数高，其中在杭锦旗越冬虫茧最高密度达240头／m^2;2009年商都县越冬虫茧平均密度迭86．8头／m^2，活茧密度为46．8头／m^2，是历年的7．2倍。根据越冬基数、春季降雨量以及蜜源作物推断，2009年草地螟幼虫发生危害严重．但实际结果越冬代成虫蛾量比较大，不同地区蛾峰、蛾量有些差异，幼虫发生危害普遍较轻，因此，需进一步探索影响草地螟预测预报的因子，以提高预报的准确性。

Abstract: The over winter amount, pupation and emergence progress,adult population dynamics of Meadow Moth （Loxostege stietiealis L.）were observed systematically in Erdos and Ulan Qab from 2008 to 2009.The results showed that in part of banners/ counties of Erdos and UlanQab in 2008,the over wintering larvae of Loxostege sticticalis distributed widely,and the cocoon amount was higher, in which the over winter cocoon density up to 240/m^2 in Hangjin Banner. In 2009,the average density of over winter cocoon was 86.8/m^2 in Shangdu County （living cocoon density 46.8/m^2）, which was 7.2 times than it in past years. Based on the over winter amount, spring rainfall and honey crops, it could be inferred that larvae of Loxostege sticticalis would cause severe damage in 2009,but actually Loxostege sticticalis larvae made light damage, although with larger winter generation adult amount.Therefore, the effect factors of Loxostege sticticalis forecast need further studying.
