Abstract

Abstract: Wild boar is an important vector for the spread of African swine fever (ASF).The wild boar population in Shennongjia forestry district is high and widely distributed.It is of profound significance to investigate the distribution of wild boar in Shennongjia forestry district for the prevention and control of ASF.In this study,117 infrared cameras and 287 line transects were used to record the individuals and trace sites of wild boar in Shennongjia forestry district.In addition,the distribution of wild boar in Shennongjia forestry district was predicted by using the Maximum Entropy Model,which was then combined with residential areas and traffic arteries in Shennongjia forestry district.We further applied the Kernel density estimation method to analyze the risk of ASF spread by wild boar in Shennongjia forestry district.Field investigation recorded a total of 2 070 wild boars,droppings,footprints,nests,and other traces throughout Shennongjia forestry district,with an estimated population of 18 424 wild boars.In Shennongjia,the areas with high wild boar density,such as Songbai Town,Yangri Town,Xinhua Town,provincial highway S307,and national highway G209,had an extremely high risk of ASF spread by wild boar.The areas about 4 km away from the extremely high-risk areas had high risk,while the risk of ASF spread by wild boar in other areas was medium or low.This study shows that Songbai Town,Yangri Town,Xinhua Town,provincial highway S307,national highway G209,and surrounding regions are key areas in the prevention and control of ASF in Shennongjia.Active monitoring and prevention should be done in these key areas to monitor the dynamic changes of ASF in real-time.

Key words: Shennongjia forestry district, Wild boar, African swine fever, Risk analysis

摘要： 野猪是非洲猪瘟(ASF)传播的重要媒介,神农架林区野猪种群数量高、分布广,调查野猪分布对ASF防控有着重要意义。本研究首先通过布设红外相机117台、样线287条调查神农架林区野猪实体和痕迹位点后,应用最大熵模型预测林区野猪分布,再根据野猪、居民区、交通要道的空间分布数据,应用核密度估计法分析神农架林区各地野猪传播ASF的风险。调查发现野猪实体及其粪便、足迹链、巢穴等共2070处,遍布神农架林区全境,预估野猪数量为18424头;林区松柏镇、阳日镇、新华镇、省道S307和国道G209沿线等野猪密度高、人口集中的地区为野猪传播ASF极高风险区;极高风险区约4km外的地区为高风险区;其他地区为中低风险区。本研究表明,松柏镇、阳日镇、新华镇、省道S307、国道G209及周围地区是ASF疫情防控工作中的重点区域,应在这些重点区域做好主动监测防控工作,实时监测ASF动态变化。
