1, Species: Star Longhorn, Brown Longhorn, Light Shield Green Longhorn 2. Occurrence characteristics: The host is citrus, fig, lotus, apple, pear, cherry, peach, plum, walnut and tea. The adults ate branches and tender skin, and the leaves became incomplete; the larvae ate the trunk and main roots, plucked into the xylem for several months under the skin, and evacuated the defecation holes outwards to push out some of the dung, reducing the tree potential. After subcutaneous feeding around the trunk, the entire plant often dies. 3, control methods: (1) Kill adults, assassinate eggs and newly hatched larvae. (2) Toxic larvae: Apply 80% of dichlorvos EC 10 to 50 times liquid to lay eggs to kill early larvae; Older larvae can use fine wire hooks to draw dung from ventilation defecation holes and then insert 1 to 2 80% dichlorvos or 40% omethoate EC 10 to 50 times liquid cotton balls, sealed with wet mud after application. (3) Applying white within one meter of trunk to prevent adult spawning has a certain effect.
