河北省白蜡窄吉丁发生情况调研

Investigation and prevention suggestions on the occurrence of Agrilus planipennis in Hebei province

白蜡窄吉丁(Agrilus planipennis)是白蜡属(Fraxinus)树木的一种重要蛀干害虫,在我国多地局部发生。该研究调查了白蜡窄吉丁在河北历史上的发生情况、分布现状及危害特点,并对该虫向河北中南部蔓延的危险性进行分析,提出防治建议。调查结果表明:白蜡窄吉丁曾在唐山、秦皇岛地区局地发生,现保持较低虫口水平;张家口市主要在发生怀来县,危害十分严重;目前在承德地区规模爆发,造成大量白蜡树死亡,并已扩散到廊坊地区,向河北中南部传播扩散风险高。该虫主要危害北美引进的白蜡树种,对本地白蜡危害较轻或不危害。建议各级林业和园林部门应对该害虫引起高度重视,并进行检疫、监测、防治技术等研究。

Emerald ash boreris an important trunk borer of the ash tree,which occurs locally in many places in China.In this study,we investigate the occurrence,distribution and hazard characteristics ofemerald ash borerin Hebei Province,and analyze the risk ofemerald ash borerspreading to the central and southern parts of Hebei Province.The results show thatemerald ash borerhas occurred locally in Tangshan and Qinhuangdao while currently having a low population level.In Zhangjiakou,emerald ash borermainlyoccurs in Huailai County, and the harm is very serious. At present,the outbreak in Chengde has caused the death of a large number of ash trees,and has spread to Langfang,and there is a high risk of the spread to central and southern Hebei. The insect mainly harms the ash tree species introduced from North America, and has little or no harm to the native ashtrees.It is suggested that forestry and landscape departments at all levels should attach great importance toemerald ash borer and conduct research on quarantine,monitoring and control technology.
