芒果象甲Sternochetus Pierce昆虫是芒果的重要害虫,明确其可能适生的区域对该虫的科学监测及防治意义重大。本文利用芒果象甲属中主要3种:印度果核芒果象S.mangiferae Fabricius、果核芒果象S.olivieri Faust、果肉芒果象S.frigidus Fabricius的已知分布点数据和亚洲地区的14个环境地理变量图层,运用GARP生态位模型结合GIS空间分析模块预测了该虫在中国的潜在地理分布,结果表明芒果象甲具有较强的扩散蔓延趋势,对我国的芒果产业构成较大的潜在威胁。
Mango weevil Sternochetus Pierce insect is an important pest of mango, clear the area may be suitable for its scientific monitoring and prevention and control of the worm is of great significance. In this paper, three main species of Asteraceae are used: the known distribution points of S. mangiferae Fabricius, S. olivieri Faust, S. frigidus Fabricius and 14 environments in Asia Geographic variable layer, using GARP niche model combined with GIS spatial analysis module to predict the potential geographic distribution of the insect in China, the results show that mango weevil has a strong tendency to spread, poses a greater potential threat to China’s mango industry .
