ABSTRACT

Whole, ethanolic, hexanic, lyophilized extracts of several plants and anacardic acid tested in respect of their influence on the oviposition behavior of Aedes fluviatilis (Lutz) at 100, 10 and 1 ppm concentrations. Extracts of Allium stivum, Jatropha curcas, Mikania schenkii, Poinciana regia and Spatodea campanulata had a repulsive effect (α=0.05) on females at 100 ppm, those of Anacardium occidentale, Bidens segetum and Caesalpinia peltophoroides were also repelent at 10 ppm. Extracts of Coriandrum sativum (100, 10 and 1 ppm), Chara Zeylanica (10 ppm), Cupressus sempervirens (10 ppm), Foeniculum vulgare (10 ppm) and Spatodea campanulata (1 ppm) were attractive to the females; 13 (52.0%) of the extracts tested, did not influence the oviposition behavior.

RESUMO

Extratos brutos, etanólicos, hexânicos, liofilizados de diversos vegetais e ácido anacárdico foram testados quanto a sua influência sobre o comportamento de oviposição das fêmeas de Aedes fluviatilis (Lutz), nas concentrações de 100, 10 e 1 ppm. Os estratos de Allium sativum, jatropha curcas. MiKania schenkii, Poinciana regia s Spatodea campanulata mostraram-se repelentes (α = 0,05) para as fêmeas na concentração de 100 ppm e os de Anacardium occidentale, Bidens segetum e Caesalpinia peltophoroides também na de 10 ppm. Os extratos Coriandrum stivum (100, 10 e 1 ppm), chara zeylanica (10 ppm), Cupressus sempervirens (10 ppm), Foeniculum vulgare (10 ppm) e Spatodea campanulata (1 ppm) atrairam a oviposição das fêmeas; 13 (52,0%) dos extratos testados foram indiferentes as fêmeas nas concentrações utilizadas.
