摘要: 谷象是世界性的重要害虫。目前,在国内仅在少数地区有发生,亟需对其适生区进行预测。根据谷象的已知地理分布及其相关的气候参数,运用CLIMEX适生性分析软件及ArcGIS地理信息系统,对该虫在中国的适生性进行了预测分析。预测结果表明,在目前气候条件下,谷象在中国的适生程度高、适生范围广,适生面积约占中国的一半,主要集中在中国的东南部地区,除新疆外,其余省市区均有其适生区域。因此,必须加大谷象在中国进境粮食和国内粮食调运中的检疫力度,采取相应的防控措施,严防该虫的入侵和扩散。

Abstract:  Sitophilus granarius Linnaeus is an important pest worldwide. At present, it only appears in a few areas in China, but it is necessary to predict its suitable living areas in China. According to the geographical distribution of S.granarius and the related climate parameter, we analyzed its adaptability in China using the CLIMEX (adaptability analysis software) and ArcGIS (geographic information system). The results showed that under the current climate conditions, S.granarius has a broad spectrum of adaptability and a wide distribution, the geographical distribution approximately accounted for half of China, which was mainly concentrated in the southeast of China. Almost all the provinces were the adaptability areas of S.granarius except Xinjiang province. Therefore, we must enhance the quarantine strength of S.granarius in China\|imported grain and domestic grain transportation, take corresponding prevention and control measures to strictly prevent the invasion and spread of this pest.
