苹浅褐卷蛾Epiphyas postvittana原产澳大利亚,是澳大利亚西南部、新西兰、英国及美国多种经济作物的重要害虫,目前尚未在全球范围广泛分布。由于其地理分布范围窄、寄主植物广泛、形态鉴定困难、能够对农作物造成较大的经济危害以及具有遗传多样性等特点,目前已被多数国家列为检疫对象并提出严格的检疫要求。而2007年该虫在美国加州地区的定殖使得研究人员对该虫能够造成的危害程度引起了再次的关注。在我国,该虫也被列为对外检疫对象,但是相关报道相对较少。作为检疫性害虫,对其相关信息的综合掌握是进一步进行有害生物风险分析的基础和保障。本文详细描述了苹浅褐卷蛾的地理分布、寄主范围、发生为害与环境条件的相互关系等,以期为该虫进行进一步风险分析及对其的检疫措施的制定和实施提供重要的信息与依据。
Epiphyas postvittana Originating in Australia, it is an important pest of many cash crops in southwestern Australia, New Zealand, the United Kingdom and the United States and is not yet widely distributed worldwide. Due to its narrow geographical distribution, wide range of host plants, difficult morphological identification, which can cause great economic harm to crops and has genetic diversity, it has been listed as a quarantine subject by most countries and stringent quarantine requirements have been put forward. And in 2007 colonization of the insect in the United States in California made the researchers the extent of the harm caused by the insects caused concern again. In our country, the insect is also listed as the external quarantine object, but the related report is relatively few. As a quarantine pest, its comprehensive control of relevant information is the foundation and guarantee for further pest risk analysis. This paper described in detail the geographical distribution, the host range, the relationship between the damage and the environmental conditions, so as to provide further information and basis for the further risk analysis of the pest and the formulation and implementation of its quarantine measures .
