45 - “ReMoa Tri: Mortality Response of Local Culex Mosquitoes Using Ground Ultra-Low Volume Applications in a Cage Field Trial”

As insecticide resistance in mosquitoes becomes more prevalent, it continues to have a negative impact on the operational efforts of mosquito control and threatens vector-borne disease management. ReMoa Tri, a novel triple mode of action mosquito adulticide, was developed to fight against this issue and target pyrethroid-resistant mosquitoes. The Grandview Sewage Lagoons and Byron Ponds in south central Washington have historically been considered to be hotspots for mosquito breeding and West Nile Virus. They are, therefore, some of Benton County Mosquito Controls’ most problematic areas in the district. It has been suspected for some time that these populations of mosquitoes have developed insecticide resistance to some degree. A cage field trial was conducted at Benton County Mosquito Control District to evaluate the efficacy of ReMoa-Tri against these local populations of adult Culex pipiens.
