Interpretive Summary: Brown marmorated stink bug (BMSB) is a serious invasive pest that has disrupted IPM programs for apple growers. To reduced insecticide inputs for this pest, we used border sprays for BMSB and other well established IPM tactics such as mating disruption for other key pests. We found that we were able to lower insecticide inputs by up to 75%, but we saw no difference in beneficial insect diversity. This approach provides the means to effectively manage BMSB in apple orchards with far less insecticide inputs.

Technical Abstract: We have demonstrated that management of the invasive Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) can be accomplished using a systems-level approach termed Integrated Pest Management-Crop Perimeter Restructuring (IPM-CPR). This approach incorporates tactics to provide behavioral management for key pests, while conserving and promoting beneficial insects. We conducted on-farm comparison of IPM-CPR with standard grower practices for managing H. halys, codling moth Cydia pomonella (L.) (Lepidoptera: Tortricidae), oriental fruit moth Grapholita molesta (Busck) (Lepidoptera: Tortricidae), and Lygus lineolaris Palisot de Beauvois (Hemiptera: Miridae) in commercial apple orchards in 2014, 2016, and 2017 in three states. Incidence of key pests and fruit injury at harvest were used as a measure of success of the program and the amount of insecticide applied for each management program was compared. Amount of active ingredient used was 20-75% lower in the IPM-CPR treatment compared with grower standard. The majority of the time, there were no differences between the IPM-CPR and the standard grower’s practice in terms of H. halys numbers in baited pyramid traps and stink bug injury at harvest. Internal worm damage from codling moth and oriental fruit moth in the IPM-CPR treatment were significantly lower than the grower standard in 2014 and 2017. Despite a reduction in insecticide use, there was no impact of management approach on beneficial insect diversity or impact. Overall, IPM-CPR in apples successfully managed key orchard pests, including H. halys, and used significantly less insecticide than a standard insecticide-based management program and could be adopted as a systems-level approach.
