Insecticidal activity of compounds from Ailanthus altissima against Spodoptera littoralis larvae

Popis výsledku v původním jazyce

We determined the efficacy of Ailanthus altissima extracts, obtained using solvents of various polarity, in terms of acute and chronic toxicity, antifeedant efficacy and larval growth inhibition of Spodoptera littoralis. Different efficacy was found forindividual fractions, in terms of both acute and chronic toxicity, as well as antifeedant efficacy and growth inhibition of S. littoralis larvae. Fractions 1 and 2, obtained at the beginning of the separation period, were the only ones to cause significant chronic toxicity accompanied by larval growth inhibition. A major proportion of tocopherol isomers were detected in these fractions. On the contrary, fractions 5 and 6 caused acute toxicity, associated with significant antifeedant efficacy and relatedstrong growth inhibition of S. littoralis larvae. Five major quassinoids (Ailanthone, Chaparrinone, Glaucarubinone, 13(18)-Dehydroglaucarubinone and Shinjulactone H) were detected in fraction 5, which showed the greatest efficacy in term
