Survey
Approved Method(s)
| Method | Detail | NAPIS Survey Method |
|---|---|---|
| Trap | 27 - Wing Trap Kit, Plastic | 3001 - General Trapping Procedure |
Trap Spacing:
When trapping for more than one species of moth, separate traps for different moth species by at least 20 meters (65 feet).
Method Notes:
01/16/13: The large plastic delta trap has been approved as another trap option for surveying for Thaumatotibia leucotreta. The wing trap and large plastic delta trap are the preferred traps.
The wing trap and the diamond trap are both effective traps for Thaumatotibia leucotreta. In order to standardize data and trap procurement,
it is preferable that states use the wing or large plastic delta trap. However, if states find reason to use the diamond trap, it is acceptable for negative data reporting. Diamond traps will not be available through the Survey Supply Ordering Database.

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.
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 the PPQ-S&T Plant Pest Risk Analysis (PPRA) Laboratory.
The SAFARIS team used a climate suitability model for false codling moth occurrence in the continental United States to support CAPS survey planning. The model predicts the suitability of an area for false codling moth occurrence based on the likelihood of favorable climate conditions for the pest occurring using tools and data within SAFARIS. The detailed method used in this assessment is described here.

Key Diagnostic or Identification
Approved Method(s)
ID/Diagnostic:
Morphological.
Mistaken Identities:
Male T. leucotreta are unlikely to be confused with any native North American tortricid. Females may appear superficially similar to other Grapholitini and a genitalic dissection may be necessary to confirm identity.
Not present in U.S.: Cryptophelbia peltastica, Mussidia nigrevenella, and Thaumatotibia batrachopa. Genitalia or male secondary sexual characters can be used to separate T. leucotreta from these other species.
