Virginia: Brown Marmorated Stink Bug Appearing In Sweet Corn – Treatment Options

Owen Taylor
By Tom Kuhar, Entomologist, Virginia Tech April 12, 2012

I was contacted recently by a VCE Agent in Frederick Co. Mark Sutphin about my recommendations for stink bug bug control in sweet corn. Frederick County is one of the counties that has very high densities of the invasive brown marmorated stink bug.

        
         

After sending him my reply, I thought that others in Virginia may also benefit from this information. So here it is below:

Fortunately for sweet corn producers, unlike tree fruit growers, BMSB should not cause any drastic changes in chemical control strategies unless the grower is relying primarily on transgenic Bt sweet corn for worm control. Bt will not control stink bugs. Most of the insecticides that growers are already spraying on sweet corn should control BMSB.

The table below is a copy of the insecticide performance report based on our research on vegetable crops in Virginia in 2011.

In the western portions of Virginia, probably applications twice per week during silking and until harvest should control them even under heavy pest pressure. In eastern counties, insecticide applications at least 3 times per week are probably needed to control both corn earworm and the BMSB.

Selected insecticides were evaluated at Virginia Tech in 2011 using green bean dip bioassays on brown marmorated stink bug nymphs and adults, as well as field efficacy trials on bell peppers. For the latter, four weekly spray applications were made using a backpack sprayer, and % stink bug injury to pepper fruit was assessed on three post-spray harvest dates (in Aug). Insecticides were ranked based on their average performance across all three experiments.
