Biosurveillance and Biocontrol of Emerald Ash Borer - Phase 2


 

Project Partners: Robert Venette (1 and 2), Brian Aukema (1), Angela Gupta (1), Jeffrey Hahn (1), Jennifer Schultz (1), Cy Kosel (3), Rachel Coyle (3), Ralph Sievert (4), Philip Potyondy (4), Jonathan Osthus (5) and Monika Chandler (5)
Project Period: 07/01/2014 - 06/30/2017

Emerald ash borer (EAB) biological control uses parasitoid wasps to reduce EAB populations and is still experimental in practice. However, biological control is the only practical EAB management strategy for natural forest ash and is a component of urban EAB management. We will improve biological control implementation with the following.

  • Biosurveillance of EAB: Engage citizen scientist volunteers to monitor EAB populations statewide using a native wasp, the smoky winged beetle bandit. This harmless wasp specifically hunts metallic wood boring beetles (buprestids) including EAB as food for their offspring. Citizen scientists can survey the type of beetle prey the wasps are capturing and help with early detection of EAB if it is present in the area. Our goals are to better delimit EAB populations and educate the public about EAB. Additionally, biosurveillance will monitor for similar high risk wood-boring beetles that are not documented in Minnesota.  More information about biosurveillance
  • Track EAB infestation core: Continue monitoring ash health, EAB and EAB biological control agents in the core infested area of the Twin Cities. This study was initiated in 2011 and will provide answers about the importance of multiple management activities.
  • Expand biological control implementation: Biological control was initiated in 2010 and biological control agents have been released at most known infestations. EAB is spreading so new detections are inevitable. The biological control effort will be expanded to address new EAB finds and continue existing site monitoring.
