Redbanded Stink Bug, an Emerging Pest on Soybeans

Redbanded stink bugs (Piezodorus guildinii) has been present in soybean fields for decades, but they were not found in numbers to consider it a pest of economic concern.  Growers were much more focused on other stink bugs, such as the southern green stink bug, green stink bug and brown stink bug and tailored their control efforts to reducing damage from the more populous insects.  However, after decades of treating for the other species, the redbanded stink bug has also developed some resistance to organophosphates, allowing their numbers to swell enough for them to be noticed in scouting events and cause economic damage.  Scientists have also been able to attribute damage from these insects to delayed maturity syndrome of soybeans.  Researchers advise rotating chemical insecticide options to help control the redbanded stink bugs populations.
