摘要
玉米根萤叶甲(Diabrotica virgifera virgiferaLeconte)是一种原产北美洲南部和中美洲北部并于1992年以来在欧洲快速传播扩散的危险性玉米害虫。该虫对我国玉米生产构成严重威胁。为了防范其入侵,本文在概述其生物学和传播蔓延趋势的基础上,利用基于生态位概念的GARP软件对该虫在我国的潜在适生区域进行了预测。研究显示适生区广布于黑龙江、吉林、辽宁、内蒙古、新疆、河北、北京、天津、山东、山西、陕西、宁夏、甘肃、江苏、安徽、河南、湖北、四川、云南和西藏等省区,其中最适生区主要位于东北平原的南部、华北平原的南部、渭河平原及其南北附近地区。据此结果,对其远距离传入中国的可能途径做了分析,对高危地区进行了分析判断,最终提出了检疫与防范建议。
As one of the most devastating pests of corn, the western corn rootworm, Diabrotica virgifera virgifera Leconte, which likely originated from the bordering region between North America and Central America, has been rapidly expanding its distribution into Europe since 1992. With its significant invasion and pest status, it poses a potentially- destructive threat to corn production in China. To prevent its invasion into China, the biology and dispersal history of the subspecies were reviewed, and its potential geographic distribution in China was predicted using GARP software in this paper. This rootworm could establish in the provinces of Heilongjiang, Jilin, liaoning, Inner Mongolia, Xinjiang, Hebei, Beijing, Tianjin, Shandong, Shanxi, Shaanxi, Ningxia, Gansu, Jiangsu, Anhui, Henan, Hubei, Sichuan, Yunnan and Tibet. Among the above regions, the southern Northeastern Plain, the southern North China Plain and the Wei River Plain, overlapping the main corn belts in the country, were expected to be most suitable for the potential invader. The possible introduction routes, locations vulnerable for invasion and quarantine measures of the western corn rootworm were analyzed and discussed.
