This pest risk assessment (PRA) was developed in response to an internal Plant Protection and Quarantine (PPQ) request to update the pest list in preparation for a new operational work plan for plums from Chile. We did not consider any production, harvest, post-harvest, shipping, or storage conditions during the development of this PRA. As such, fruit produced under different conditions were not evaluated and may pose a different pest risk. We used scientific literature, port-of-entry pest interception data, and information from the government of Chile to develop a list of pests with quarantine significance for the United States. These are pests that occur in Chile on any host and are associated with the commodity plant species anywhere in the world. Then we determined the likelihood of introduction for each pest. 

The following organisms are candidates for pest risk management because they have met the threshold for unacceptable consequences of introduction and can follow the commodity import pathway:

- Ceratitis capitata, high likelihood of introduction

- Accuminulia buscki, low likelihood of introduction

- Chileulia stalactitis, low likelihood of introduction

- Lobesia botrana, medium likelihood of introduction
