Abstract: The North American subterranean termite Reticulitermes flavipes Kollar (Isoptera: Rhinotermitidae) has a strong social and economic impact worldwide, damaging houses and wooden structures in urban environments, causing considerable losses. Infestation foci in central Chile in recent years have expanded. We evaluated the toxic effect of extracts from new leaves of Schinus molle L. (Anacardiaceae) onto R. flavipes. The extracts were prepared with two solvents, distilled water, and ethanol. The toxic effect of the extracts was evaluated by direct and indirect exposure tests, determining mortality caused by several concentrations, and analyzed with Anovas and Tukey multiple comparison tests, and Probit analysis to obtain the mean lethal concentrations (LC50). The extracts, particularly the ethanol one, had clear toxic effects on the termite, and increased with concentration. The least LC50 obtained on the 7th day after treatment was 0.59% w/v by direct exposure to the ethanolic extract. These results demonstrate the effectiveness of the extracts on R. flavipes, so the leaves from S. molle could be used in biopesticide preparations for integrated management of this pest, previous field evaluation and economic studies.
