Climate Suitability Map
A Climate suitability map is now available. This survey should only be considered in the states with appropriate climate conditions and suitable hosts for this moth.
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-S&T Plant Pest Risk Analysis (PPRA) Laboratory.
The SAFARIS team used a climate suitability model for tomato leafminer occurrence in the continental United States to support CAPS survey planning. The model predicts the suitability of an area for tomato leafminer occurrence based on the likelihood of three favorable climate conditions for the disease occurring using tools and data within SAFARIS. The detailed method used in this assessment is described here.
9/11/12: A new type of sticky trap insert (liner), which uses a hard type of adhesive, has been approved for use in Phthorimaea absoluta CAPS surveys. This product has been tested by CPHST and has been found to be as effective as the traditional trap liners at capturing Phthorimaea absoluta. In addition, the identifiers are able to pre-screen a higher number of specimens from the hard glue liners, and the specimens tend to be of higher quality. The product name in the IPHIS survey Supply Catalog is Large Plastic Delta Trap - Liners - Hard Glue.
Trap color is up to the state and does not affect trap efficacy.

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.
Key Diagnostic or Identification
Approved Method(s)
ID/Diagnostic:
Morphological: Phthorimaea absoluta is very similar to many species in the same family, Gelechiidae, including other tomato pests. For final identification, it is necessary to carefully examine adult male genitalic structures. Use Brambila et al. (2010).
Mistaken Identities:
Present in U.S.: Two other similar-looking species that may be found as pests in tomato fields are: Keiferia lycopersicella and Phthorimaea operculella.
