Codling Moth Resources

The interception of codling moth infested apples during import inspections in Taiwan (2004) lead to stricter requirements for exporting apples to the taiwan market from the pacific region of the US. As a result, a new Systems Approach Work Plan was developed for 2005 to insure only codling moth-free shipments are sent to Taiwan. However, there were two interceptions of codling moth in 2005 season fruit that prompted small revisions to the protocol for sampling orchards and field bins. These revisions were implemented in 2006 which included manditory training for orchard sampling personnel without a pesticide consultant's license, and the addition of a minimum of 150 fruit cut during field bin sampling. There were two detections of codling moth from the 2006 crop, but no changes were made to the plan for 2007. The 2007 crop had two back-to-back interceptions of codling moth. This has not resulted in any changes to the 2008 plan regarding codling moth. However, there could be a couple of unrelated changes added to the plan as a result of changes to the China work plan: adding wooly apple aphid and the fungus Phacidiopycnis washingtonensis to the quarantine pest list. The Systems Approach Work Plan and the sampling protocols apply to Washington, Idaho, Oregon and California apple production areas. UPDATE: Anarsia lineatella (Peach twig borer) was added to the Taiwan Quarantine Pest list, as per EXCERPT 3/16/09 and is indicated on the work plan on this web site.

The pages listed below give growers, fieldmen, packers and shippers the necessary information for following the guidelines setforth by the current work plan and sampling protocols. Included here are webpage links to the full Work Plan, instructions and forms required for the sampling protocol to prove fruit come from supplying orchards at low risk for codling moth infestation (as required by Sec. 1 of the Work Plan), and codling moth identification information. If you'd rather skip the webpages and download the files directly, links are provided in the column to the right for the relevent PDF files. These files are current as of July 2009. Updates will be posted if/when they are made available by APHIS.
