Lure Attachment: Attaching lures to traps
IMPORTANT: Do not include lures for other target species in the trap when surveying for this target.
Lure Notes: August 22, 2016: For the 2017 season and beyond, two lure options are approved: 1) Ethanol and 2) Alpha Pinene UHR Lure; or 1) Ethanol, 2) Alpha Pinene UHR Lure, and 3) Monochamol Lure. The second combination is the approved method for the CAPS targets Monochamus alternatus and Monochamus urussovii. If you are surveying for Monochamus alternatus and Monochamus urussovii using the three lure combination, you may also report negative data for Hylobius abietis. If you are only surveying for Hylobius abietis, you may use just the Ethanol and Alpha Pinene UHR Lure combination.
Note: There are two alpha pinene products available in the IPHIS Ordering Database: 1) Alpha Pinene Lure and 2) Alpha Pinene UHR Lure. The Alpha Pinene Lure is an un-gelled lure in a bottle dispenser that is used by the PPQ Program for Tomicus piniperda (pine shoot beetle). This lure should only be used for this target.
The Alpha Pinene UHR Lure is a polysleeve, ultra-high release dispenser used for other EWB/BB targets. This lure should be used with the Ethanol Lure for the following targets: Hylobius abietis, Hylurgops palliatus, Hylurgus ligniperda, Monochamus alternatus and Tomicus destruens.
The release rate of this lure is highly temperature-dependent. However, CAPS has listed a conservative length of effectiveness that will be effective for even the warmest climates in the CAPS community.
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: Confirmation of Hylobius abietis is by morphological identification. It is difficult to identify H. abietis to the genus. Identification may require assistance from taxonomists specializing in Hylobius.
Mistaken Identities: It resembles species in the genera Hylobius, Pissodes, and Eudociminus.
Domestic:
Hylobius congener and Hylobius pales fill a similar niche.
Eudociminus mannerheimi is native to the eastern U.S. It is similar in size but infests primarily cypress trees.
Exotic:
Pissodes castaneus and Pissodes pini.
