| Biolarvicides, based on crystal toxins of certain strains of are highly effective against mosquito larvae. The wide variety of formulations based on spore-crystal complexes intended for ingestion by target insects, are the result of many years of research. Depending on the formulation and environmental conditions, is generally effective from 1-4 weeks after application. In this work we aimed to detect the extracellular proteases in mosquito breeding areas as the environmental factors that affect the life of the biolarvacide formulations. Thus, 120 bacterial isolates from some mosquito habitats in Turkey were obtained and screened for their putative proteolytic extracellular protease (s) against strain 2362 mosquitocidal toxin. Two isolates, identified as and according to 16s rDNA, have extracellular proteases which have high activity against crystal toxin. The bioassay applications using the larvae of the were also performed. The results confirmed the efficacy of the aquatic bacteria on the crystal toxin. The proteolytic activity of the bacteria isolated from aquatic mosquito environments indicates that the microbial content of the mosquito habitats should be taken into account when bacterial insect controlling agents, like formulated larvicide, are to be used. |
