Research Project: Maximizing Adoption by Demonstrating the Compatibility of Insecticide Netting with Diverse Pest Management Tactics at Food Facilities

Location: Stored Product Insect and Engineering Research

Project Number: 3020-43000-034-014-R
Project Type: Reimbursable Cooperative Agreement

Start Date: Oct 1, 2020
End Date: Aug 31, 2024

Obj. 1 Synergize long-lasting insecticide-incorporated netting (LLIN) deployment to improve phosphine fumigation efficacy in food facilities. Obj. 1A Assess whether LLIN use decreases the number of fumigations. Obj. 1B Evaluate whether LLIN use increases the efficacy of fumigations. Obj. 1C Determine whether LLIN use can mitigate the spread of phosphine resistant insects. Obj. 2 Demonstrate compatibility of LLIN deployment with ultra-low volume formulation (aerosol) insecticide use in food facilities. Obj. 2A Assess whether LLIN use decreases the number of aerosol applications. Obj. 2B Determine whether LLIN may increase the efficacy of aerosol applications. Obj. 2C Ascertain whether rotating the mode of action for the aerosol or LLIN improves efficacy. Obj. 3 Improve outcomes of novel residual contact insecticide use by pairing with LLIN deployment at food facilities. Obj. 3A Assess whether LLIN may decrease reliance on residual contact insecticides for purposes of sanitation. Obj. 3B Predict decrease in immigration by combined or individual use of residual insecticide and LLIN. Obj. 4 Develop value-added resources for US stakeholders and assess economic feasibility of incorporating LLIN into management programs. Obj. 4A Maintain and expand digital repository of management information on stored product pest management. Obj. 4B Assess projected change in expenses when using LLIN alone or in combination with other pest management tactics above.

We will use a combination of laboratory, semi-field, and field experiments to determine how best to incorporate long-lasting insecticide netting (LLIN) into existing management programs at food facilities. This will include serial exposure assays to long-lasting insecticide netting and aerosols, fumigants, and residual contact insecticides. We will also be using behavioral assays to determine movement parameters of stored product insects after exposure. This project will involve collaborating with local stakeholders for tests at facilities, and also demonstration of tactics in pilot scale mills and warehouses to reduce insect infestation and progeny.
