Abstract: The aim of this study was to establish reference concentrations (LC 50 e LC 90 ) of aqueous extracts of Bidens pilosa on the land snail Subulina octona, in order to assess the changes caused by 24 and 48 h exposure to the sublethal concentration regarding species' fecundity, hatchability and in offspring produced after exposure to confirm the presence of tannins, saponins and flavonoids in this plant species. Eggs newly hatched and 30 day-old snails were exposed to sublethal concentration, calculated for adult… Show more

“…There are descriptions using plastic terrariums with 9 cm diameter and 6 cm depth. The final volume was 5 mL with mollusks exposed through dermal contact directly with the extract [ 12 ]. Silva and collaborators [ 13 ] used plastic terrariums with capacity of 250 mL containing 5 adult mollusks exposed to a final volume of 8 mL sprayed with manual sprayer.…”

“…So far, many plants with high molluscicidal activity, including Cinnamomum camphora , Bidens pilosa , Pulsatilla chinensis , Hedera helix and Glycyrrhiza spp., are rich in pentacyclic triterpenoid saponins. These saponins, with different chemical structures, show distinctly different molluscicidal activity …”

“…Além das saponinas, diferentes classes de metabólitos que apresentam atividade biocida reconhecidos na literatura destacam-se os flavonoides, terpenos, alcaloides, antraquinonas e cumarinas (Alcanfor et al, 2001;Souza et al, 2013;Treyvaud et al, 2000;Alcanfor et al, 2001;Souza et al, 2013).). Até a década de 1980 já tinham sido estudadas cerca de 1.100 espécies vegetais no mundo, buscando na busca de compostos coma atividade moluscicida(?)…”
