Look for cavities in the peel.

Zhang Zhongmin said that because citrus maggots are fruit flies that lay eggs in citrus, there are often small cavities on the surface of the peel; Citrus damaged by citrus maggots has the characteristics of falling fruit before ripeness and yellow before ripeness. Therefore, when choosing citrus, the public can first see whether the peel is ripe and natural, and then see if there are small cavities.
