Survey
Approved Method(s)
| Method | Detail | NAPIS Survey Method |
|---|---|---|
| Trap | 22 - Wing Trap Kit, Paper | 3001 - General Trapping Procedure |
| 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:
Recommended trap service schedule:
- Every two weeks: Check traps to collect samples.
- Every month: Replace the trap liners, as the sticky surface becomes covered with dust, leaves, etc.
Approved Lure(s)
| NAPIS Code | Product | Dispenser | Effectiveness | Compound(s) | 34 | Lymantria mathura Lure | string dispenser | 180 days | Z3Z6-9R10S-epo-19Hy Z3Z6-9S10R-epo-19Hy |
|---|
Lure Attachment:
IMPORTANT: Do not include lures for other target species in the trap when surveying for this target.
Lure Notes:
The Lymantria mathura lure is effective for 180 days. Using the lure for the full length of effectiveness is strongly encouraged.
- At the start of the survey season, attach the lure to the trap by stapling the string dispenser to a twist-tie and then stapling the twist-tie to the
upper half (lid) of the trap on the non-sticky area. - The twist-tie will reduce repeated handling of the string dispenser if the trap needs to be replaced at any time during the season.
- If the trap needs to be replaced for any reason, remove the twist-tie with attached lure from the old trap and staple it to the new trap.
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 Likelihood of Establishment Map is now available. This survey should only be considered in the states with appropriate conditions and suitable hosts for this insect.
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 PERAL.
The SAFARIS team used a likelihood of establishment model for Rosy moth occurrence in the continental United States, that was developed by PPQ PERAL and NCSU CIPM, to support CAPS survey planning. The model predicts the suitability of an area for Rosy moth occurrence based on the likelihood of favorable conditions for the insect occurring using tools and data within SAFARIS. The detailed method used in this assessment is described here.
