摘要
This study mainly investigatied the geographical distribution patterns of Dastarcus helophoroides in China and analyzed the thresholds of temperature and humidity in its distribution regions, to provide a theoretical basis for employing %D.helophoroides% in controlling long-horned beetles. In China, %D.helophoroides% distributed in the regions from the north, Meihekou City(41°41′ N) of Jilin Province to south, Shenzhen City(22°38′ N) of Guangdong Province, and from west, Zhongning county(105°40′ E) of Ningxia Huizu Autonomous Region to east, Meihekou City(125°54′ E) of Jilin Province. The insect distributed widely in Guangdong, Jiangsu, Anhui, Hebi, Henan, Shanxi, Shandong, Ningxia, Shannxi, Beijing, Jilin and Liaoning. The annual mean temperature in the distribution regions was higher than 5.4 ℃, the average temperature in July was above 22.6 ℃, the average temperature in January is higher than -15.2 ℃, and the extreme low temperature was -36.8 ℃. The annual humidity in the distribution regions was above 47.2% and the annual precipitation was above 186.3 mm.
