The larvae bite ginger, which leads to suffering decay and lose the value of the goods.

The prevention and control of special odoriphaga, first to timely discover and eradicate odoriphaga damage by alien plants in the field, to avoid the harvest into the well cellar; two is to do well cellar cleaning and spraying disinfection work.
