摘要 从地理评估和管理标准、传入的可能性、传播途径、定殖、定殖后扩散的可能性及橘小实蝇危害性评估等方面对橘小实蝇传入中国风险进行定性分析,筛选了橘小实蝇传入中国的风险因子.根据我国各气候大区的30 a(1961-1990)的平均气温、月最高平均气温、月最低平均气温及年降雨量等气候因子和橘小实蝇的发生规律,将我国地域划分为适生区、次适生区、非适生区,明确了南亚热带湿润大区、边缘热带湿润大区、边缘热带亚湿润大区为橘小实蝇的适生区;暖温带湿润大区、北亚热带湿润大区、南亚热带亚湿润大区、高原亚温带湿润大区为橘小实蝇的次适生区.提出了降低橘小实蝇风险的管理措施,为制定检疫政策提供依据. The invasion risks as well as the risk factors of Bactrocera dorsalis were determined based on the analysis results on B. dorsalis geographical distribution, possibilities of its invasion mutes, possibilities of its colonization and expansion thereafter and its hazard assessment. China was classified into suitable region, suitable region and unsuitable region according to the year average temperature (1961 -1990) , highest month average temperature, lowest month average temperature and year average precipitation in each climate zone. The suitable region includes south of subtropical humid area, edge of tropical humid area, and edge of subtropical humid area. Meanwhile warm temperate humid area, north of subtropical humid area, south of subtropical subhumid area and highland subtemperate humid area constitute the subsuitable region. The measures to decrease B. dorsalis were given and this will help to make quarantine policy.
