[Effect of several extracts derived from plants on the survival of larvae of Aedes fluviatilis (Lutz) (Diptera: Culicidae) in the laboratory]. / Influência de diversos derivados de vegetais na sobrevida das larvas de Aedes fluviatilis (Lutz) (Diptera: Culicidae) em laboratório.

The larvicidal properties of 34 plant extracts were tested against Aedes fluviatilis (Lutz) (Diptera: Culicidae) larvae, at 100, 10 and 1 ppm concentrations; 26.6% of the extracts enhanced larval mortality (alpha = 0.05) at 100 ppm (Anacardium occidentale, Agave americana, Allium sativum, Coriandrum sativum, Nerium oleander, Spatodea campanulata, Tibouchina scrobiculata and Vernonia salzmanni). Anacardic acid (A. occidentale) was effective at 10 ppm and A. sativum (crude extract) at 1 ppm.
