Is one of the main pests of jujube trees. In my area is widespread, serious harm. The leaves of the victims were curly, dry and early deciduous, resulting in a half-death status of the tree growth recession and a serious victimization, which caused great damage to the construction and development of the windbreak and sand fixation forest. This was an urgent problem to be solved in forestry production. For this reason, we conducted a survey and experimental study on the harmful effects and control methods of Psittaci on the apple jujube, and the preliminary results are summarized as follows for reference.
