    摘要:

    [目的]枣疯病是我国枣树的一种毁灭性病害。近年来,该病害在陕西枣区发病面积日益扩大,造成枣树成片死亡,对陕西的红枣产业构成严重威胁。本文旨在明确枣疯病在陕西省的风险等级,为枣疯病的管控提供依据。[方法]采用有害生物风险分析程序和方法,从枣疯病发生现状、潜在危害性、寄主的经济重要性、定殖扩散的可能性以及风险管理的难度等5个方面,对枣疯病在陕西省的风险性进行了定性和定量综合评估。[结果]枣疯病在陕西全部枣区适生,在陕西省的风险综合评价值R=2.84,危险等级为Ⅰ级。[结论]枣疯病在陕西属于特别危险有害生物,对陕西红枣产业有很高的风险。根据其危险等级,提出应清除病原和严格检疫、加强枣园管理和防治媒介昆虫等管理对策。

    Abstract:

    [Aim] Jujube witches' broom disease is a devastating disease, caused by Canidatus phytoplasma ziziphi. In recent years, the disease has been spreading in northern Shaanxi and Guanzhong, causing the death of trees and posing a severe threat to the jujube industry. The purpose of this study was to determine the risk level of jujube witches' broom in Shaanxi Province and put forward corresponding management countermeasures.[Method] The risk of jujube witches' broom disease in Shaanxi Province was evaluated qualitatively and quantitatively using pest risk analysis procedures and methods on five aspects, including distribution, potential economic hazard, the economic importance of the host, possibility of colonization, and diffusion and difficulty of risk management.[Result] The conditions in the whole of Shaanxi Province were suitable for the disease. The comprehensive risk evaluation value of the disease in Shaanxi Province was R=2.84, and the risk level was gradeⅠ.[Conclusion] This disease poses a high risk to the jujube industry in Shaanxi. According to the risk level of jujube witches' broom disease, the management countermeasures of eliminating pathogen and strict quarantine, strengthening jujube orchard management, and controlling vector insects were put forward.
