[目的]为在江西省对桔小实蝇进行有效的监测和预警提供科学依据。[方法]利用桔小实蝇的分布点数据和环境因子数据,通过GARP生态位模型预测桔小实蝇在江西省的潜在分布区域。[结果]桔小实蝇在江西省的适生面积占全省面积的2/3以上。在24°～26°N赣南盆地的大部分区域,年平均气温在19～20℃,是桔小实蝇的高适生区。在26°～27°N的赣州北部的部分地区以及吉安西南部、抚州、鹰潭、上饶东南部的少部分地区,年平均气温在18～19℃,是桔小实蝇的中度适生区。在26°～30°N的滨湖、赣江中下游、抚河、袁水区域和赣西南山区,年平均气温在17～18℃,是桔小实蝇的低适生区。赣东北、赣西北和长江沿岸地区,年平均气温为16～17℃,是桔小实蝇的非适生区。[结论]该研究结果表明桔小实蝇的实际分布与GARP的预测分布基本相符。
[Objective] The research aimed to provide a scientific basis for effective monitoring and early warning of Trichosanthes flies in Jiangxi Province. [Method] Using the distribution point data and environmental factor data of the orange fruit fly, the potential distribution of the orange fruit fly in Jiangxi Province was predicted by the GARP ecological niche model. [Result] The suitable area of fruit fly in Jiangxi Province accounted for more than two thirds of the province area. In 24 ° ~ 26 ° N Gannan basin in most of the region, the annual average temperature 19 ~ 20 ℃, is the high habitat of the orange fruit fly. The average annual temperature ranged from 18 ℃ to 19 ℃ in some areas of northern Ganzhou and in the southwest of Ji’an, Fuzhou, Yingtan and the southeast of Shangrao at 26 ° ~ 27 ° N. . In the lake of 26 ° ~ 30 ° N, the middle and lower reaches of the Ganjiang River, Fuhe, Yuanshui area and the southwestern Jiangxi mountainous area, the annual average temperature is 17 ~ 18 ℃, which is the low-yielding area of the fruit fly. In northeast Jiangxi, northwestern Jiangxi and the Yangtze River, the annual average temperature is 16 ~ 17 ℃, which is the non-suitable area for the fruit fly. [Conclusion] The results of this study showed that the actual distribution of Trichosanthes flies was basically consistent with the predicted distribution of GARP.
