摘　　要：为了准确把握释放天敌昆虫防治栗山天牛的最佳时期,对宁城县栗山天牛的生物学特点及发生规律进行研究。结果表明:栗山天牛在宁城县3年1代,跨4个年度,7月底至8月初为成虫羽化高峰期。由此得出,释放肿腿蜂防治栗山天牛低龄幼虫的最佳时期为8月底至9月,而释放花绒寄甲防治栗山天牛蛹的最佳时期是6月至7月初。从2006年起,宁城县采取栗山天牛幼虫和蛹期释放天敌防治,成虫期利用专用黑光灯诱杀的综合治理措施,使栗山天牛的发生面积由1 133 hm 2下降到287 hm 2,下降了74.7%。Massicus raddei （Blessig） （Coleoptera： Cerambycidae） is a wood borer with long generation period and developmental uniformity of Quercus mongolica Fischer in Ningcheng County, Inner Mongolia, China. In order to control it by releasing natural enemies in appropriate period, biological characteristics and occurrence regularity of Massicus raddei （Blessig） was studied in this paper. Results showed that one generation of Massicus raddei was three years and crossed four years, and the adults’ peak emergence stage was from the end of July to the early August. So the best time of releasing Sclerodermus to control young larvae of the beetles was formed at the end of August to September, and releasing Dastarcus helophoroides to control pupae was from June to early July. So, since 2006, Sclerodermus had been being released to control young larvae, and Dastarcus helophoroides to control pupae, and Massicus raddei adults trapped by the special black light. After several years, the oak forestry areas infected by the oak long-horned beetles dropped from 17000 mu to 4300 mu. Thus, it was showed that using natural enemies to control the wood borer was effective.
