枣实蝇在中国适生性初步研究

Potential geographic distribution of Ber fruit fly,Carpomya vesuviana Costa,in China

枣实蝇是严重危害枣类生产的重要害虫。本文采用CLIMEX模型与ArcGIS分析相结合的预测方法对枣实蝇在我国的适生性进行了研究,在明确枣实蝇CLIMEX参数指标体系和适生性评判标准的基础上,分析了该实蝇在我国的适生区域和适生程度。结果表明,枣实蝇在我国的适生区域广泛,适生程度偏高:山东、河南、陕西、山西、河北、北京、天津及云南大部分地区,辽宁和广西西部,四川和甘肃东部,江苏、安徽和湖北北部,以及新疆西部和北部的适生程度为高;辽宁和广西中东部,四川西部,重庆大部,湖北和安徽中部,江苏中北部,福建、江西和湖南的零星地区具有中度适生性。鉴于枣实蝇在我国的适生性研究结果,建议采取有效的防控策略,加强枣实蝇检疫措施,完善监测体系,严防该虫的入侵和扩散。

The ber fruit fly, Carpornya vesuviana Costa, is one of the most important insect pest causing consloerable economic losses of Ziziphus spp. in the world. The potential geographic distribution of ber fruit fly in China was predieted in this study using CLIMEX and AreGIS. The result presented a wide potential distribution of bet fruit fly and the suitable level was high. The regions, including most parts of Shandong, Henan, Shaanxi, Shanxi, Hebei, Beijing, Tianjin and Yunnan, west of Liaoning and Guangxi, east of Sichuan and Gansu, north of Jiangsu, Anhui and Hubei, west and north of Xinjiang, were predicted with high suitability. In the meantime, regions such as east and center of Liaoning and Guangxi, west of Sichuan, most part of Chongqing, center of Hubei and Anhui, center and north of Jiangsu and several small part of Fujian, Jiangxi and Hunan were with medium suitability. In order to prevent the introduction and spread of ber fuit fly, the quarantine and monitor measures should be enhanced more in China.
