Part of the 2017 Oregon Master Gardener Advanced Training series. Ongoing efforts to manage Brown Marmorated Stink Bug (BMSB) in the Pacific Northwest will benefit from the arrival of the samurai wasp, a specialist parasitoid of BMSB eggs. This presentation will identify evidence of BMSB damage, describe management options, and identify how to recognize biological control from the samurai wasp.

Presented by: Dr. David Lowenstein
