| Toxicological efifects of four extracts proceeding from the stem cortex of the amazonic plant Paullinia clavigera D.R. Simpson (Sapindaceae) by decoction, ethanolic, chlorophormic and hexanic on three arthropods: Rhynchophoruspalmarían (Linnaeus, 1758) (Curculionidae), Eupalamides cyparissias (Fabricius, 1777) (Castniidae) and Artemia franciscana (Kellog, 1906) (Artemiidae) in Ucayali, Peru were studied. The four extracts at the highest concentration tested were: decoction at a proportion 1:10 (w/v), ethanolic, chlorophormic and hexanic at 100 mg·L-1. Toxic effects were evaluated at 12,24,48 and 72 hours on larvae of III in star of R. palmarum and larvae of II instar of E. cyparissias; and at 24 and 48 hours on nauplii of A. franciscana.
