本文根据蔗扁蛾生物学及生态学特性的研究 ,利用地理信息系统ArcView 3 2分析预测了该虫在中国的可能适生分布范围。结果表明 ,蔗扁蛾在中国可能的最适宜分布范围大体在 1 6 5～ 2 7 9°N ,97 8～ 1 1 9 7°E ,涉及华南、西南地区的 7个省 (自治区 )的 79个县 (市或地区 ) ;潜在适宜分布范围大体在 2 2 9～ 37 1°N ,91 1～ 1 2 2 7°E范围内 ,涉及华东、华南、西南、华中、西北、华北共 1 9个省 (自治区、直辖市 )的 2 4 0个县 (市或地区 )。
According to the biological and ecological characteristics of Plutella xylostella, ArcGIS 3 2 was used to predict the possible distribution of this parasite in China. The results showed that the most suitable distribution range of Plutella xylostella in China was between 165 and 279 ° N and 97 8 to 1 1 9 7 ° E in 79 provinces (autonomous regions) in South China and Southwest China Counties (cities or areas); the potential suitable distribution ranges from 229 to 371 ° N and 91 1 to 122 7 ° E, involving 1 9 in East China, South China, Southwest China, Central China, Northwest China and North China Provinces (autonomous regions and municipalities) 240 counties (cities or regions).
