长林小蠹在中国的适生区预测及风险分析OA

Hylurgus ligniperda is a quarantine pest for imported plants in China and also an invasive alien pest in the country,which has posed potential threats to forest resources and biosecurity.To evaluate the distribution of its potential suitable habitats and the risk of its spread in China,two species distribution models within the BIOMOD2 modeling platform were employed to predict its potential suitable areas.Meanwhile,a comprehensive risk analysis was conducted from five aspects,including species distribution characteristics,potential economic hazards,distribution and economic importance of host plants,transmission possibility,and difficulty of risk management.The results showed that the total area of potential suit-able habitats for H.ligniperda in China accounted for approximately 37.9％of the national territory,with a risk value of 2.53,indicating that it is an extremely dangerous forest pest.Its potential suitable range is extensive and the spread risk is extremely high.It is necessary to promptly implement quarantine and control measures to reduce the risk of its colonization and spread in China.
