Abstract:The threshold temperature to Asecodes hispinarum Bouek was studied in laboratory. The results indicated that A. hispinarum had different emergence rate at different temperatures, most of them would died after 48 h at 2℃, 33℃ and 36℃,and all died after 24h at 0℃ and 39℃. Based on Arcview GIS 3.2 and the study of the biological characteristics of A. hispinarum, the possible suitable establishment areas of the pest in China was forecasted. The results indicate that the possible optimum establishment areas included 6 spots belonging to Hainan, ranged from 16.53°N to 19.1°N and from .61°E to 112.33°E. The possible suitable establishment areas included 25 spots belonging to 5 Provinces, ranged from 20.03 included 172 spots belonging to regions of West-South China, East China and Middle China, ranged from 22.3°N to 33.4°N and 98.50°E to 122.1°E.
