Taxonomic Position: Coleoptera : Buprestidae
Pest Type: Insects
Pest Code (NAPIS): INAHRPA
This pest is a member of the following lists:

Exotic Wood Borer / Bark Beetle
Oak
These Approved Methods are appropriate for: 2015
Major Hosts identified in the Host Matrix:
Oak

This list includes important economic or environmental hosts but does not represent all major hosts of the pest. Check CAPS pest datasheet for complete list of hosts.
Human and Animal Pathogens Transmitted:
Not known to transmit any human or animal pathogens.
Plant Pathogens and Organisms Vectored:
Not known to vector any pathogens or other associated organisms but damage may lead to invasion by secondary pests. Armillaria spp. may occur after trees are infested (Moraal and Hilszczanski, 2000a; 2000b).
Survey
Approved Method(s):
Method Product Name / Instructions NAPIS Survey Method
Visual See Silagyi et al., (2010; rev. 2011). 3031 - General Visual Observation
Trap 19 - Prism Trap, Purple
 3001 - General Trapping Procedure
Cerceris Sample Cerceris wasps. 3015 - Cerceris Sample
Trap Spacing and Placement: When trapping for woodborers or bark beetles, separate traps with different lure combinations by at least 30 meters (98 feet).
Method Notes:
04/17/14: For the 2014 survey season and beyond, for Cerceris surveys, you will now need to ensure that the appropriate host species (Ash for Agrilus planipennis and Oak for the other three Agrilus targets) is within a 200 meter (650 foot) radius of the sampling site. 02/27/13: When reporting data into NAPIS, use the NAPIS code 00581 - Trap;Prism;Purple (No Lure). By using this code for A. biguttatus, you are stating that you have conducted both a visual survey (as described above) and have used a purple prism trap. 07/02/12: The Cerceris Wasp Survey Protocol is now available and is listed in the References section below.
Identification


ID/Diagnostic: Morphological

Morphological: Pupae and adults may be identified by a taxonomist. Agrilus biguttatus may be confused with indigenous and exotic buprestid species.
Mistaken Identities:
Present in the U.S.: Agrilus planipennis (Emerald ash borer), Agrilus cuprescens, Agrilus cyanescens, Agrilus derasofasciatus, Agrilus hypericici, Agrilus obsoletoguttatus, Agrilus pilosovittatus, and Agrilus sinuatus. (There are 171 Agrilus species documented in America north of Mexico.)
