Survey
Approved Method(s)
| Method | Detail | NAPIS Survey Method |
|---|---|---|
| Trap | 108 - Paper Delta Trap, 2 sticky sides, Brown | 3001 - General Trapping Procedure |
| Trap | 110 - Paper Delta Trap, 2 sticky sides, Green | 3001 - General Trapping Procedure |
| Trap | 109 - Paper Delta Trap, 2 sticky sides, Orange | 3001 - General Trapping Procedure |
Trap Spacing and Placement:
When trapping for more than one species of moth, separate traps for different moth species by at least 20 meters (65 feet).
Method Notes:
Trap should be used with ends open. Trap color is up to the State and does not affect trap efficacy.
Recommended trap service schedule:
Recommended trap service schedule:
- Every two weeks: Check traps to collect samples.
- Every month: Replace the traps, as the sticky surface becomes covered with dust, leaves, etc.
Approved Lure(s)
| NAPIS Code | Product | Dispenser | Effectiveness | Compound(s) | 62 | Lymantria xylina Lure | string dispenser | 180 days | Xylinalure |
|---|
Lure Attachment:
IMPORTANT: Do not include lures for other target species in the trap when surveying for this target.
Lure Notes:
The Lymantria xylina lure is effective for 180 days. Producing the lure is time-consuming, so using the lure for the full length of effectiveness is strongly encouraged. For negative data reporting, use the lure with the paper delta trap.
- 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 trap. The twist-tie will reduce repeated handling of the string dispenser when replacing traps throughout the season.
- When replacing the trap (monthly), 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.
