2011 Annual Report
1a.Objectives (from AD-416)
The objectives of this cooperative research project are (1) to investigate host selection, host colonization and the nutritional ecology of the Asian Longhorned Beetle (ALB), ANOPLOPHORA GLABRIPENNIS; (2) to identify ecological and behavioral traits vulnerable to intervention and development of detection, monitoring, biological control and other IPM strategies; and (3) to develop technologies and methodologies for optimally implementing these strategies into eradication and population management programs directed at ALB and closely related invasive insect pest species.
1b.Approach (from AD-416)
Complementary field and laboratory studies will be conducted. (1) Comparative studies of adult ALB behavioral responsiveness to characterized formulated host odor blends of ACER MONO, ACER NEGUNDO, ACER PLATANOIDES and ACER TRUNCATUM will be evaluated in an olfactometer under laboratory conditions at BIIRU. (2) Comparative studies of adult ALB behavioral responsiveness to ACER MONO, ACER NEGUNDO, ACER PLATANOIDES and ACER TRUNCATUM trees will be evaluated in an olfactometer under laboratory conditions at BIIRU. (3) Evaluate adult ALB behavior as a function of physiological and biological factors (e.g. pre vs. post maturation; mated vs. non-mated; pre vs. post oviposition). (4) Adult ALB attraction to olfactometer active blends will be evaluated under natural field conditions in China, including evaluation of formulation, blend ratio and attractive radius. This research will collectively complement our ongoing investigations of host selection by ALB and identification of artificial lures for detection, monitoring, management and eradication of ALB; and elucidate the mechanisms of host selection and colonization by ALB.
In collaboration with the Simon Frasier University, preliminary lab studies were initiated to compare the relative attraction of ALB attraction to Painted Maple trees vs. odors (volatiles) isolated from Painted Maple. Studies are in progress at the time of this report. In collaboration with Animal Plant Health Inspection Service (APHIS), we interfaced our degree day model of ALB development with geographic information systems (GIS) to provide federal, state and international agencies with weekly forecasts of ALB, thereby optimizing early detection, survey and control strategies. We identified the geographic and host range of ALB in Asia, which when interfaced with GIS, will focus exploration, discovery and collection of exotic natural enemies of ALB in China as potential biological control agents of ALB in the US and Europe. Communication with Cooperators was by emails and phone calls.
