Insecticide Resistance Testing of Formulated Products in North Carolina Mosquitoes 2024-2025 Grant uri icon

abstract

  • Mosquitoes can develop resistance to insecticide active ingredients (AI) over time when exposed to sublethal doses. Mosquito exposure to insecticide formulated products (FP) during ultra-low volume (ULV) applications occurs via direct contact with aerosolized liquid droplets containing AI and other ingredients to enhance effectiveness. Limited data has been collected on efficacy of FP against North Carolina mosquitoes. A wind tunnel will be constructed to simulate field droplet sizes and densities and compared to field trials using NC mosquito populations (e.g., Aedes, Culex, Anopheles) against FP (e.g., BioMist 3+15 [AI: permethrin], Duet [AI: sumethrin/prallethrin], ReMoa Tri [AI: fenpropathrin, abamectin, C-8910, Dibrom [AI: naled]). All data will be entered into NCVectorSurv.
