This work analyzed the chemical composition and biological activities of Piper cyrtopodon and Piper krukoffii essentials oils, collected in the Amazon. These oils were obtained by hydrodistillation and the chemical compounds were characterized by gas chromatography/mass spectroscopy (GC-MS), showing limonene and selinene were the majority compounds of Piper cyrtopodon and Piper krukoffii, respectively. The essential oils of both species presented toxicity against Artemia salina and the antimicrobial activity showed greater responses to gram-positive bacteria. The insecticidal activity of essential oils had a mean activity against larvae and mosquitoes of Aedes aegypti, being possible agents for the control of vectors.  aAedes aegypti  aPiper  aÓleo Essencial1 aRAMOS, G.
