It can be confirmed that it is a Coleoptera leaf beetle pest, which basically points to the scarab. This pest has the characteristics of nocturnal infestation and concentrated damage. In the early stage, there were black velvet gill scarab, and in the middle and late stage (at present or just a few days ago, there were apple hairy scarab, green scarab and so on). ).

It can be effectively controlled by spraying phoxim underground, spraying beta-cypermethrin on the crown and compounding certain organophosphorus pesticides.
