Larvicidal activities against Aedes aegypti have been determined in the ethanolic extracts obtained from 51 Brazilian medicinal plants. Eleven of the 84 extracts studied showed significant (LC 50 < 100 μg mL −1) activities against larvae, with extracts from Annona crassiflora (root bark, LC 50 = 0.71 μg mL −1; root wood, LC 50 = 8.94 μg mL −1) and Annona glabra (seed, LC 50 = 0.06 μg mL −1) showing the highest activities. The results obtained should be of value in the search for new natural larvicidal compounds.
