摘要
基于桔小实蝇的生物学和生态学特性,在Excel平台上统计分析了江苏省13个站点20年的气象数据。数据分析表明江苏省是桔小实蝇的潜在适生分布区;有效积温分析表明,桔小实蝇一年内在江苏省可发生5~7代;基于地理信息系统ArcM ap G IS的桔小实蝇地理分布预测图表明,其潜在的高发期为7月下旬和8月上旬。预测结果还显示,桔小实蝇在常州、溧阳、吴县东山、南京和吕泗等31°N^32°N地区有相对较好的适生性。
Based on the biological and ecological characteristics of the oriental fruit fly, Bactrocera dorsalis Hendel, we analyzed the meteorological data in twenty years from 13 sites in Jiangsu Province using Microsoft Excel system. The result shows that Jiangsu Province is a potential suitable establishment area for the pest. Effective accumulated temperature analysis indicates that the pest may have five to seven generations a year in the province. The geographical distribution map forecasted via the geographic information system （GIS） ArcMap indicates that regions such as Changzhou, Liyang, Wuxian Dongshan, Nanjing and Lüsi, whose altitude fall in 31°N to 32°N, show relatively better suitability. The map also indicates that the pest can establish its population or have outbreaks easily from late July to early August.
