摘　　要：2006～2008年，对省内贵州地道中药材栽培和野生半夏蓟马的分布与危害情况进行了调查，并调查了贵阳市小河区金竹镇栽培半夏蓟马的田间消长规律。结果表明：调查的县（区）均有半夏蓟马分布，人工栽培和野生半夏蓟马发生地块12％～23％；田间消长规律出现明显的3峰型，发生期在4月下旬至9月下旬，发生高峰日分别在5月25日、7月14目和8月13日。提出了田间防治措施，仅供生产上参考。Distrlbution of thrips and its damage on Pinellia ternate, including the cultivated and the wild, were investigated from 2006 to 2008 in Guizhou, and population dynamic of the thrips was investigated on cultivated P. ternate in Jinzhu town, Xiaohe district, Guiyang city. The results showed that there are distributions of the thrips in all investigated regions, either on the cultivated and the wild P. ternate with 12 % - 13 % of occurred fields. The growth and decline trends of the thrips have three obvious peaks during the end of April to the end of September. The highest population happens on May 25 ,July 14 and August 13. A controlling measure in the field was put forward for reference in production of P. ternate.
