Approved Method(s)
| Method | Detail | NAPIS Survey Method |
|---|---|---|
| Trap | 101 - Large Plastic Delta Trap Kits, Orange | 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:
12/27/13: Leucoptera malifoliella is now available as a survey target. Previously, L. malifoliella was not available as a survey target due to the large number of non-targets caught in traps and the time-consuming identification process.
Now, a new type of sticky trap insert (liner), which uses a hard type of adhesive, has been approved for use in Leucoptera malifoliella CAPS surveys. These new trap liners allow the identifiers to process specimens more quickly. 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.
