Survey Recommendations
The following are recommendations for executing the survey using the approved methods for pest surveillance. The recommendations are developed through literature review and consultation with subject matter experts.
Likelihood of Establishment Map:

A Likelihood of Establishment Map is now available. This survey should only be considered in the states with appropriate conditions and suitable hosts for this pathogen. The map was produced by the SAFARIS Team. SAFARIS is a modeling framework that enables PPQ to quickly respond to emergencies, efficiently survey for pests, and assess potential pest impacts by collecting critical geospatial data and developing predictive models. SAFARIS is developed and maintained by the NC State University, Center for Integrated Pest Management (CIPM) with support from PPQ PPRA.

Key Diagnostic or Identification

Approved Method(s)
ID/Diagnostic:
Morphological.
Mistaken Identities:

This species has some similarities to Scrobipalpopsis petasitis (present in North America and Europe) and S. tetradymiella (present in the United States). Two similar species that are found in potato include Phthorimaea operculella and Symmetrischema tangolias. Both larvae and adults of these species are smaller than those of T. solanivora.
