ResumoTo study toxicity of 76 laboratory-grown strains of planktonic cyanobacteria to mosquito larvae, hydrophilic and lipophilic cell-free extracts of cyanobacteria were incubated with larvae of the Aedes aegypti mosquito and death percentages were followed during 2 days. Toxicity was clearly associated with hepato - and neurotoxins of the samples. A strain of Microcystis aeruginosa was most effective, and caused death of the larvae due to a single hepatotoxin. Pure mammalian neurotoxin, anatoxin-a, was also toxic, and probably acted as a neurotoxin with the mosquito larvae.
