Laboratory Bioassays to Assess Potential Control Strategies for Brown Marmorated Stink Bug

Posted: April 19, 2011

Laboratory bioassays were conducted this winter at the Penn State Fruit Research and Extension Center to assess the toxicity of various insecticides against adults of brown marmorated stink bug (BMSB). The results provided valuable information relative to insect management during the upcoming growing season. The biology and behavior of brown marmorated stink bug (BMSB, aka Asian stink bug) present many challenges. BMSB has a plethora of available host plants and has the ability for unrestricted movement. Insect biology and monitoring issues are undefined and there is no biological control. Each instar (except eggs) can cause damage, and initial injury on fruit is inconspicuous. Alternate management options to be investigated during the growing season include border applications, treatment of surrounding vegetation, and trap crop plantings. Research on spatial and temporal distribution will also be conducted.

Mortality was determined on adults from overwintering colonies at 4, 24, 48, 72, 96, and 120 hours after treatment. Surviving individuals were kept for further observation. The complete results and the implications relative to BMSB management during the growing season are presented in the attached slide presentation.
