Blueberry maggot regulations
The blueberry maggot (BM), caused by the insect Rhagoletis mendax, is a destructive pest of commercial blueberry fruit. The maggot attacks the fruit of host plants, leaving the berry non-viable. BM hosts include members of the family Ericaceae, including Vaccinium (blueberry) and Gaylussica (huckleberry and lingonberry).
The pest was first observed in the United States in 1914, in both Maine and New Hampshire. BM is now found throughout the eastern United States and southeastern Canada including states and provinces of Alabama, Connecticut, Delaware, Florida, Georgia, Maine, Maryland, Massachusetts Michigan, New Hampshire, New Jersey, New York, North Carolina, Pennsylvania, Rhode Island, Tennessee, Virginia, West Virginia, New Brunswick, Nova Scotia, Ontario, and Prince Edward Island. It is not known to occur in Oregon.

A quarantine was established against blueberry maggot, Rhagoletis mendax, in July of 1974 under Oregon Administrative Rules (OAR) 603-052-0115. Commodities covered comprise all fresh fruit of blueberry and blueberry plants (except when free from soil and growing media; clumps of soil or growing media larger than 1/2 inch diameter will be cause for rejection). Areas under quarantine include all states, districts, and territories of the United States east of and including the States of North Dakota, South Dakota, Nebraska, Kansas, Oklahoma, and Texas. All states of the United States west of North Dakota, South Dakota, Nebraska, Kansas, Oklahoma, and Texas are not included therein.

All commodities covered are prohibited entry into Oregon from the area under quarantine with the exception of items listed in below:

  1. No restrictions are placed by this quarantine upon the entry into the State of Oregon of fruits which upon arrival are frozen solid and which are held under refrigeration to assure their solid frozen state.
  2. Fruits affected by this quarantine, which have been held in cold storage for a continuous period of at least 40 days during which period the temperature in said cold storage area has been maintained at 32° F or less, may be admitted into the State of Oregon providing that the lot or shipment of the same is accompanied by an official certificate, issued by an agency of the state of origin authorized to do so, evidencing compliance with the requirements of this subsection.

Commodities in violation of quarantine shall be immediately returned by the person receiving to the point of origin or, at his option and without expense or indemnity paid by the Department, destroyed by such person.
