桔小实蝇Bactrocera dorsalis(Hendel)是重要的植物检疫性有害生物,可危害46个科250多种果蔬等作物,在世界上大多数热带、亚热带果蔬产区均有分布。为了解桔小实蝇在贵州潜在危害范围和程度,基于桔小实蝇的生物学特性、已知分布资料和气象数据,采用CLIMEX与Arc GIS软件对桔小实蝇在贵州的适生性、年发生代数和动态进行分析、预测。结果表明,桔小实蝇在贵州适生程度较高,高度适生区面积占全省总面积的88%,桔小实蝇在贵州的发生代数主要为2-6代,发生4到5代的区域最多,常年发生区和季节发生区面积较小,大部分区域为二者间的过渡区,结果为贵州桔小实蝇监测、预警、防控和优化果蔬产业布局提供科学指导。 Bactrocera dorsalis (Hendel) is an important phytosanitary pest that can endanger crops of more than 250 kinds of fruits and vegetables in 46 families and is distributed in most tropical and subtropical fruit and vegetable producing areas in the world. In order to understand the extent and extent of the potential damage of the orange fruit fly in Guizhou, based on the biological characteristics of the fruit fly, known distribution data and meteorological data, using CLIMEX and Arc GIS software for adaptability of orange fruit fly in Guizhou, Occurrence of algebra and dynamic analysis, prediction. The results showed that the orange fruit fly in Guizhou suitable for a higher degree of fitness, height of the area accounted for 88% of the total area of ​​the province, the occurrence of orange fruit fly in Guizhou algebra is mainly 2-6 generations occurred 4 to 5 generations Of the area, perennial and seasonal areas are small, most of the transitional areas between the two results provide the scientific guidance for the monitoring, early warning, control and optimization of fruit and vegetable industry in Guizhou.
