Title: Diversifying IPM after harvest: The promise of implementing insecticide netting to protect stored product

Abstract: Globally, $100 billion USD in postharvest commodities are lost due to insect feeding and damage. Control of these insects has historically relied on fumigation, but there are increasing regulatory, consumer, and biological constraints on the use of fumigants. As a result, there has been a push to diversify integrated pest management (IPM) after harvest. In our project, we have quickly assessed and supported adoption of long-lasting insecticide-incorporated netting (LLIN) in stored product IPM programs. We have found that exposure to deltamethrin netting results in a 2–3-fold reduction in movement and 95–100% reduction in dispersal after contact by multiple species and life stages of stored product insects compared to controls. Moreover, we have found that direct mortality ranged from 73–98% for 5 of 8 stored product species after brief 5-minute exposures to the insecticide netting. Further, deployment of insecticide netting via one of three methods in pilot-scale warehouses resulted in a 93% reduction in infestation and 99% fewer progreny produced in commodities after releasing thousands of insects compared to control warehouses containing netting with no insecticide. We found the netting can be successfully incorporated into an attract-and-kill trap to intercept stored product insects on the perimeter of facilities. Importantly, we found that multiple brief exposures to the net result in the same effects on stored product insects as longer, continuous exposures. We have worked with the producer of LLIN label it for use in postharvest settings in the US. Finally, there has been robust interest by stakeholders in adopting netting at food facilities across the Great Plains. Taken together, our project has successfully demonstrated the ability for insecticide netting to act as an effective novel tactic, while diversifying IPM programs at food facilities across the US to protect our commodities as they make their way to the end consumer.
