Abstract:

Abstract: In the light of research achievements on the factors affecting growth and development of Bursaphelenchus xylophilus and its vector insects, four basic conditions (i.e., plant autoeciousness, B. xylophilus pathogen, vector insects and environment) affecting the survival and spread of B. xylophilus were comprehensively analyzed by applying the theories and methods of synthetic assessment of fuzzy mathematics, geographical information system and geostatistics, and the relatively exactly potential distribution region of B. xylophilus in China and the more detail potential distribution region of B. xylophilus in Yunnan province were estimated. The above results would provide scientific bases for making policies in quarantining, preventing and controlling B. xylophilus.
