A complex of stink bugs (Pentatomidae) occurs as an annual pest in Louisiana soybean.  These insects are capable of directly decreasing yield loss in addition to significantly reducing seed quality.  Chemical control is the primary IPM tactic used for the management of stink bugs in soybean.  The redbanded stink bug, Piezodorus guildinii (Westwood), is known to be more difficult to control than other stink bugs.  During 2012, field trials evaluated insecticide efficacy against redbanded stink bug at two separate sites in Louisiana soybean to validate performance.  Many of the products provided significant levels of control, although multiple products did not consistently reduce numbers of redbanded stink bug below the action threshold level of 24/100 sweeps.  These results provide a summary of insecticide effectiveness and will be used to support Louisiana soybean IPM chemical recommendations.
