Complementary field and laboratory studies will be conducted. (1) Host tree volatiles emanating from ALB host tree species will be collected under natural field conditions (aerations and extractions) and will be characterized using GC-MS, GC-EAD and other appropriate analytical procedures at Simon Fraser University (SFU). (2) Adult ALB behavioral responsiveness to formulated blends will be evaluated in an olfactometer under laboratory conditions at BIIRU. (3) Adult ALB attraction to EAD and olfactometer active blends will be evaluated under natural field conditions in China, including evaluation of blend composition and component ratio, dose, release devise, attractive radius and attraction efficiency. This research will collectively complement of our ongoing investigations of host selection by ALB, and will result in the identification of artificial lures, and protocols for utilizing these tools for prediction, detection, monitoring, management and eradication of ALB.
