Oligonychus Coffeae (Nietner), also known as spider mite, is one of the major pests mites in the tea plantation in China, which is mainly distributed in the front of the upper leaves of the tea clumps, causing the leaves to become partially dark red and dull Leaving a lot of egg shell and peeling shell on the foliage, finally causing the leaves to harden, dry, fall off, the tea garden showed a yellowish color, seriously affecting the vitality of tea plants and tea yield and quality.In order to screen high resistant germplasm, Pest breeding to provide parents, the author of 34 tea germplasm resources on the resistance of Carassius auratus were identified.
