摘要
烟翅腮扁蜂Cephalcia infumata Zhang&Wei是贺兰山国家级自然保护区危害青海云杉Pi-cea crassifolia的重要害虫.采用野外调查和室内观察相结合的方法,对烟翅腮扁蜂生物学特性进行初步研究,应用我国有害生物多指标综合评价法评价烟翅腮扁蜂在贺兰山的风险性.结果表明:烟翅腮扁蜂在贺兰山地区发生频繁,对青海云杉天然林资源造成较大威胁;烟翅腮扁蜂的风险值R=1.72,在贺兰山国家级自然保护区属中度危险性林业有害生物.提出了相应的管理对策.
Abstract
Cephalcia infumata Zhang&Wei is an important pest insect that harms Picea crassifolia in Helan Mountain National Nature Reserve.The biological characteristics of C.infumata were preliminarily studied by field investigation and indoor observation.The risk of C.infumata in Helan Mountain was evaluated by multi-index comprehensive evaluation method of pests in China.The results showed that C.infumata occurred frequently in the Helan Mountain area,which posed a significant threat to the natural forest resources of P.crassifolia and the risk value of C.infumata was 1.72,indicating that C.infumata was a moderate risk forest pest in Helan Mountain National Nature Reserve.The corresponding management measures of C.infumata were put forward.
