摘要
【目的】研究柑橘木虱在云南省的分布区域,确定限制柑橘木虱生存和扩散的关键环境参数。【方法】应用MaxEnt生态位模型软件,基于柑橘木虱地理分布记录划分柑橘木虱在云南的最适生区域,并确定影响木虱分布的主要环境限制因子。【结果】柑橘木虱高适生区集中分布于云南六大水系流域的中低海拔(200~1800 m)地区;最冷季度平均温度和年平均温度是影响柑橘木虱在云南分布的最主要限制因子,年平均气温低于15℃和最冷季度平均温度低于10℃的高海拔(1800 m以上)区域不适于柑橘木虱生存。【结论】研究结果可为柑橘木虱在云南的发生提供早期预警及有效防控,从而为解决柑橘木虱传播黄龙病难题提供理论依据。
[Purpose]To study the potential distribution area of Diaphorina citri in Yunnan Province,and to determine the key environmental parameters to limit the survival and spread of D.citri.[Method]Based on the record of geographic distribution,MaxEnt niche model software was used to divide the most suitable areas of D.citri in Yunnan and determine the main environmental limiting factors affecting the distribution of D.citri.[Results]The highest fitness areas of D.citri were mainly distributed in the middle and low altitude areas with an altitude of 200-1800 m in the six major river basins of Yunnan.Mean temperature of coldest quarter and annual mean temperature were the main limiting factors affecting the distribution of D.citri in Yunnan,while the high altitude areas(above 1800 m)with an annual average temperature below 15℃and average temperature lower than 10℃in the coldest season were not suitable for the survival of D.citri.[Conclusion]The result of this study can provide a theoretical basis for the early warning and scientific formulation of prevention and effective control of D.citri in Yunnan,so as to solve the problem of D.citri spreading Huanglong-bing disease.
