摘要
由植原体侵染引起的丛枝病和蛙皮病是世界范围内木薯生产中的重要病害,严重影响木薯块根的产量和品质,为保障我国木薯产业的可持续发展,笔者对这2种病害入侵我国的风险性进行了分析。通过检索国内外文献,结合前期木薯病害普查结果,在对这2种病害的国内外分布状况、潜在经济危害性、受害寄主的经济重要性等方面的分析基础上,采用有害生物风险性分析(PRA)程序进行分析。结果表明,丛枝病和蛙皮病的综合风险R值分别为2.19和2.31,均属于高度危险的检疫性有害生物,相关部门应对其加强检疫防范。
Cassava Witches' Broom and Frog Skin diseases are worldwide important diseases caused by phytoplasma, which could induce serious loss of yield and poor quality of root tubers of cassava (Manihot esculenta Crantz). In order to ensure the sustainable development of the cassava industry in China, these two diseases were put for risk analysis. The related progress at home and abroad and cassava disease survey results in China were retrieved from the literature, and the distribution of these two diseases and their potential economic damage as well as the economic importance of the infected host plants were described. The risk of the infection of the two diseases was evaluated by using the available software Pest Risk Analysis (PRA) developed for evaluation of alien species. The risk values of these two diseases were given accordingly and input into the PRA program to e- valuate the risk of the diseases. The PRA evaluation showed that the overall risk R values of cassava Witches' Broom and Frog Skin diseases were 2.19 and 2.31, which indicated these two diseases were pests with high risk and had to be listed for quarantine inspection.
