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: Examination by a taxonomist with expertise in the weevil subfamily Scolytinae is required for identification. Examine specimens under a microscope with 70-110X magnifications and gooseneck lighting sources.
1. To determine if the specimen is Tomicus, use Passoa and Cavey (1994) followed by Brodel (2005 - rev. 2009).
2. To determine species of Tomicus (destruens, minor, or piniperda), use Brodel (2005 - rev. 2009) with Brodel (2000).
3. To separate T. minor from T. piniperda, use Brodel (2000).
1. To determine if the specimen is Tomicus, use Passoa and Cavey (1994) followed by Brodel (2005 - rev. 2009).
2. To determine species of Tomicus (destruens, minor, or piniperda), use Brodel (2005 - rev. 2009) with Brodel (2000).
3. To separate T. minor from T. piniperda, use Brodel (2000).
