摘　　要：2005—2006年间调查白城地区桑树主要病虫害种类、发生规律及综合防治技术。研究发现北方干寒地区桑园内主要虫害为桑蓟马和叶螨,主要病害为桑萎缩病和桑赤锈病。"向海1号桑"可作为干寒地区的抗病、抗虫综合抗性最强桑树品种推广。加强桑园的抚育管理,可预防病虫害的发生或降低受害程度。及时掌握害虫及天敌种群数量的变化趋势,是行之有效的预测预报方法。应用40%丙溴磷乳油对桑园蓟马和叶螨可以同时防治,防治效果达到98%以上。应用多抗霉素是防治桑赤锈病的首选药剂,可配合使用代森锰锌。乙蒜素防治桑萎缩病效果最好。A survey was conducted to study the species, occurrence role and integrated control technique of major diseases and insect pests of mulberry during 2005-2006 in Baicheng. The major pests are Pseudcdendrothrips mori Niwa and spider mites （Tetranychidae） in the dry and cold area in north China, and the major diseases are mulberry dwarf and mulberry rust. ＂Xiang Hai No. 1＂ mulberry can be used as the best variety to be popularized in dry and cold regions due to its comprehensive resistance. To strength the nurturing management can prevent the occurrence of diseases and pests or decrease the extent of damage. Timely grasping the changing trend of pests and populations of natural enemies is an effective method for forecasting. The control effect of using 40% profenofos missible oil to control both P. mori and spider mites could reach 98%. Polyoxin is the best medicament to control the mulberry rust, which can be used together with Mancozeb. Ethylicin exhibits the optimal control effect on mulberry dwarf.
