摘　　要：【背景】青檀绵叶蚜是近几年在山东枣庄市发现危害青檀的新物种,该蚜虫对青檀造成了一定的危害。【方法】2013年对山东和安徽青檀分布地实地调查确定青檀绵叶蚜的分布情况,并结合我国环境变量,采用Maxent生态位模型对青檀绵叶蚜在中国的潜在地理分布进行预测。【结果】青檀绵叶蚜潜在高风险区大面积集中在山东,江苏和北京有零星分布;中风险区大面积集中在河北、河南、安徽和江苏;低风险区集中在山西、四川、江西、辽宁、湖北、湖南和浙江等地区。【结论与意义】青檀绵叶蚜潜在分布区集中在中国中东部地区,这对青檀分布地区预防青檀绵叶蚜发生有重要意义。[ Background ] In recent years, Shivaphis pteroceltis was identified as a new aphid species. This species is causing great damage to Pteroceltis tatarinowii in Zaozhuang, Shandong Province. [ Method ] In 2013, the distribution of S. pteroceltis in Shandong and Anhui Province was surveyed. In addition, the potential distribution of S. pteroceltis was predicted by Maxent niche model com- bined with environmental variables. [ Result ] The resuhs show that most of potential high risk areas are concentrated in Shandong Province, with limited risks in Jiangsu Province and the City of Beijing. Potential risks of invasion is considered medium in the prov- inces of Hebei, Henan, Anhui, and Jiangsu. The provinces of Shanxi, Sichuan, Jiangxi, Liaoning, Hubei, Hunan, and Zhejiang are considered as low risks. [ Conclusion and significance] The predicted distribution of S. pteroceltis, using the Maxent niche mod- el, shows that the concentration of higher risk of infestation is located in central-eastern regions of China. This is where prevention of occurrence of S. pteroceltis should focus since it is the main area for P. tatarinowii.
