China has taken a series of strict quarantine measures and prevented the entry of Mediterranean fruit fly effectively.

PRA (Pest risk analysis) has been done actively on fruits and vegetables, pest free area has been delimited according to the international standard,which have minimized negative trade effects of plant quarantine on trade,and accelerated the development of import and export trade of fruits and vegetables.
