栗山天牛是柞树的重要蛀干害虫 ,近年在辽宁省发生面积已达 6～ 7万hm2 。受害后的柞树材积生长及材质下降 ,甚至造成树木枯死。为有效控制栗山天牛危害 ,1995～ 1999年 ,进行生物学特性及防治技术的研究 ,结果查清了栗山天牛的生活史 ,掌握了栗山天牛的生物学特性。防治试验证明 ,采用卫生伐、人工捕捉、利用天敌及熏蒸剂 ,都能经济有效地防治栗山天牛 Chestnut Cerasus is an important stem borers of oak trees, in Liaoning Province in recent years, the area has reached 60,000 to 70,000 hm2. After the damage of oak tree material growth and material decline, and even cause trees dead. In order to effectively control the harm of Tian Tian cattle, from 1995 to 1999, the study of biological characteristics and prevention and treatment techniques were conducted. The results showed that the life history of Tian cattle was identified and the biological characteristics of Tian cattle were mastered. Control tests show that the use of sanitary cutting, artificial capture, use of natural enemies and fumigants, can cost-effectively prevent chestnut Tian Tian cattle
