Interpretive Summary: As the current toolbox of available chemical larvicides for use in organically enhanced aquatic environments on military installations shrinks with the termination of temephos registration in the USA, it becomes a struggle to meet the objectives of vector control while remaining eco-friendly. In the past, monomolecular films have provided effective control of mosquito larvae and pupae in a variety of mosquito habitats. Here we report on the comparison of two commercial products, CocoBear™ Larvicidal Oil and Aquatain® AMF Liquid Mosquito Film for their effectiveness against larval and pupal Culex quinquefasciatus Say in an organically enhanced container habitat. We found that CocoBear and Aquatain were equally effective against larval and pupal Cx. quinquefasciatus at 24 h in the organically enhanced aquatic habitats

Technical Abstract: The efficacy of CocoBearTM Larvicidal Oil and Aquatain® AMF Liquid Mosquito Film against larval and pupal Culex quinquefasciatus was compared (at maximum label field application rates) when applied to cement troughs treated with composted cow manure. At 1 h post treatment, CocoBear provided significantly greater reduction of mosquito larvae than Aquatain, but both products were equally effective in producing >97% control at 24 h. Each product provided >98% pupal reduction at 1 h post treatment with complete elimination of pupae from troughs at 24 h. We found that CocoBear and Aquatain proved to be equally efficacious against Cx. quinquefasciatus immatures in organically enriched aquatic habitats.
