| 中文摘要: |
| 【研究目的】椰心叶甲(Brontispa longissima)是海南地区重要的检疫性害虫,主要危害椰子(Cocos nucifera)、槟榔(Areca catechu)、油棕(Elaeis guineensis)、海枣(Phoenix dactylifera)、蒲葵(Livistona chinensis)等16种棕榈科植物。椰心叶甲自2003年在昌江首次发现以来,曾给该地区棕榈产业造成了严重威胁。随着防治力度增强,该虫的危害和扩散得到了显著控制。但因近年来椰心叶甲的危害减轻,防治力度也逐渐降低,目前椰心叶甲作为检疫性林业有害生物在昌江地区是否存在再次扩散风险,需重新评估。【方法】本文采用有害生物风险分析方法(PRA),从分布和寄主、潜在的危害性和经济影响、定植扩散风险、危险性管理难度等方面对椰心叶甲危害风险进行了定性和定量分析。【结果】结果显示椰心叶甲在海南省昌江县的风险值R=1.84 ,属于中度危险性有害生物,建议加强风险管理。 |

| 【OBJECTIVE】Brontispa longissima is an important quarantine pest in Hainan province. Its main hosts are 16 species palm plants, including Cocos nucifera, Areca catechu, Elaeis guineensis, Phoenix dactylifera, Livistona chinensis and etc. Brontispa longissima was first found in Changjiang county since 2003, and then caused a serious threat to the palm industry in the area. With the enhancement of control efforts, the harm and spread of the pest have been significantly controlled. However, in recent years, the harm of the pest is reduced, and the prevention and control efforts are also gradually reduced. At present, as a quarantine forestry pest, whether there is a risk of threat in changjiang area needs to be reassessed; 【METHOD】The Pest Risk Analysis (PRA) of B. longissima in Changjiang area was evaluated by using qualitative and quantitative analysis including distribution and the host, potential hazard and economic impact, risk of colonization and spreading, and difficulty of risk management; 【RESULTS】The results suggested that risk assessment value (R) was 1.84, thus B. longissima was a moderately dangerous pest in Changjiang area and risk management should be strengthened. |
