Effectiveness of Aquatain AMF and Cocobear™ Larvicidal Oil Against Larvae and Pupae in an Organically Enhanced Aquatic Habitat.

The efficacy of CocoBear™ Larvicidal Oil and Aquatain AMF Liquid Mosquito Film against larval and pupal was compared (at maximum label field application rates) when applied to concrete troughs treated with composted cow manure. At 1 h posttreatment, 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 posttreatment, with complete elimination of pupae from troughs at 24 h. CocoBear and Aquatain proved to be equally effective against immatures in organically enriched aquatic habitats.
