宁夏光肩星天牛、黄斑星天牛天敌昆虫的研究

Research of the Enemy of Anoplophora glabripennis and A.nobilis in Ningxia

宁夏光肩星天牛和黄斑星天牛天敌昆虫自然种群很少，主要有花绒穴甲寄生天牛的老熟幼虫、蛹、成虫，柿树螟蛾捕食天牛卵，寄生蝇、虱蝇类寄生天牛幼虫和蛹，姬小蜂寄生天牛蛹．花绒穴甲是大型杨树天牛最有价值的优势天敌种，在宁夏很多地区有少量发现．该虫自然扩散能力弱，分布狭窄，在生态条件较好的地区寄生率较高，其它昆虫偶尔发现有寄生和捕食现象，但数量极少．

The natural population of the enemy of Anoplophora glabripennis and A.nobilis is very small. In Ningxia Hui Autonomous Region, their main enemy is Dastarcus helophorides that hatched in mature larva, pupa and adults of A.glabripennis and A.nobilis.
