Photosensitization of invertebrates by natural polyacetylenes

Fourteen polyacetylenes or their thiophene derivatives, isolated from species in the Asteraceae were screened for their biological activity to mosquito larvae ( Aedes aegypti), blackfly larvae ( Simulium vittatum) and adult nematodes ( Caenorhabditis elegans). Toxicity of the compounds was found to...

More Information
Summary:Fourteen polyacetylenes or their thiophene derivatives, isolated from species in the Asteraceae were screened for their biological activity to mosquito larvae ( Aedes aegypti), blackfly larvae ( Simulium vittatum) and adult nematodes ( Caenorhabditis elegans). Toxicity of the compounds was found to be enhanced greatly by irradiation with near-UV radiation or natural sunlight. Only wavelengths less than 400 nm were effective in promoting photosensitization. The results are discussed in relation to herbivore-plant interactions.
