Specific primer pair for identifying beet coracoid and application of specific primer pair

The invention provides a molecular identification method for detecting beet coracoid by using a specific PCR (Polymerase Chain Reaction) primer. According to the method, an RAPD (Random Amplified Polymorphic DNA) technology is utilized to obtain a specific sequence of the coracocystis beet, an efficient PCR (Polymerase Chain Reaction) amplification primer is designed, a PCR detection system complementary to the efficient PCR amplification primer is established, and a specific 223bp single DNA band of the coracocystis beet is rapidly obtained. The method has the advantages of being convenient to operate, accurate in identification and the like, rapid molecular identification of the beet coracoid can be achieved, and the reaction speed of pest detection and targeted prevention and control is increased. 本发明提供了一种用特异性PCR引物检测甜菜筒喙象的分子鉴定方法。该方法利用RAPD技术获得甜菜筒喙象特异序列，并设计高效PCR扩增引物，建立与之相辅PCR检测体系，快速获得甜菜筒喙象特有223bp单一的DNA条带。该方法具有操作方便、鉴定准确等优点，可实现对甜菜筒喙象的快速分子鉴定，加快对该害虫检测以及针对性防治的反应速度。
