[目的]分析山东口岸进境矿产品植物疫情截获情况,提高矿产品有害生物疫情检出率,有效保护国门生物安全.[方法]分别从截获植物疫情变化规律、疫情类别、矿产品类型、检疫性有害生物与一般有害生物情况、来源地、不同隶属关截获情况等方面对山东口岸2008—2017年进境矿产品截获的各类疫情进行了统计分析.[结果]山东进境矿产品中截获有害生物总计54种(属),2560种次,1574批次,检疫性有害生物4种(属),29种次.进境矿产品中有害生物截获种类和种次均呈现中间多两端少的特点,以昆虫、线虫和杂草截获种类最多,占截获种类总数的87.04%,昆虫截获种次最多,占截获总种次的65.70%;有害生物的截获种类和种次均以非金属矿产截获最多,金属矿产次之;共截获4种(属)、29种次检疫性有害生物,50种(属)、2531种次一般性有害生物;截获种次前三位国家分别是朝鲜、韩国、印度尼西亚.[结论]研究结果对口岸进境矿产品疫情截获及防控提供了理论和数据支持. 相似文献

Dispersal of Liriomyza trifolii 总被引:1,自引:0,他引:1
O. P. J. M. MINKENBERG 《EPPO Bulletin》1988,18(1):173-182
The agromyzid fly Liriomyza trifolii , which has generally been considered as a secondary pest, could turn into a major international pest. Up to the seventies this leafminer occurred only in Caribbean countries, and southern and eastern USA. It then became resistant to several insecticides in Florida. Extensive transport of plant material between production areas has resulted in the establishment of this insect in many countries, despite chemical treatment before and after transport and quarantine procedures. The human-mediated dispersal of L. trifolii is described, phytosanitary and quarantine measures are reviewed and finally plant protection policy is discussed. 相似文献

Erwinia amylovora has been spreading in the Czech Republic since 1986 regardless of emergency phytosanitary measures which have been taken. Its spread follows the predominant wind direction (west to east). The infested area now covers two thirds of the area of the country. Wild Crataegus spp. are the most important and widespread host plants. E. amylovora is still regulated as a quarantine pest, and areas free from fireblight are subject to special phytosanitary measures. 相似文献

分析了外来植物有害生物传入我国蔓延危害的主要特点、发展态势及潜在风险.我国防范外来植物有害生物入侵,主要存在管理体制、法规制度、检疫手段和技术、人员素质和资金投入等诸方面问题.加强植物检疫职能、整合检疫管理力量、构建快速反应机制、确保安全服务贸易等是有效防范外来生物入侵的重要组织步骤;完善植物检疫立法和管理体制、重视技术标准研制和采用国际标准惯例、加快有害生物风险分析和重新确定检疫性有害生物名录、改进植物检疫检验手段和技术、加强非疫区和非疫生产基地建设、设立植物检疫专项基金、加强国际合作与交流等尤为迫切. 相似文献
