Status of <I>Rhagoletis</I> (Diptera: Tephritidae) Pests in the NAPPO Countries

The North American Plant Protection Organization (NAPPO) is an organization comprising plant protection regulatory officials of the three signatory countries: the United States, Canada, and México. NAPPO develops Regional Standards for Phytosanitary Measures (RSPMs) as well as discussion papers on important issues related to plant protection. The Fruit Panel of NAPPO organized a Technical Assistance Group (TAG) to develop a discussion paper on the status of pest species of Rhagoletis (Diptera: Tephritidae) within the NAPPO countries. As regulations are developed to prevent the spread of these pests both within and outside of the NAPPO countries, it was important to understand the pest status of these species. This article reviews the basic biology, host range, distribution, potential to spread, management, and regulatory status of pest species of Rhagoletis within the NAPPO countries.
