%X The composition of essential oils from two muna, Bolivian medicinal plants, derived form #Minthostachys andina$ and #Hedomea mandonianum$, were analyzed by gas chromatography/mass spectrometry. Major differences were observed in their chemical composition. Pulegone was the major component of #H. mandonianum$ oil (44.6 %) and #M. andina$ oil (22.5 %) ; menthone and isomenthone were around 33 % of these oils. Differences were also observed in their insecticidal activity against the Chagas' disease vector, #Rhodnius neglectus$ or #Triatoma infestans$ bugs exposed on impregnated oil filter papers. While #M. andina$ oil showed 30 % -50 % of mortality in both triatomine species after a period of 1 week, #H. mandonianum$ oil did not show any insecticidal activity. Nevertheless, both species had insecticidal activity (33.3 % and 50 %) when oils were topically applied. The significance of these results is discussed in relation to the variability of the chemical composition and their potential use in Chagas' disease vector control. (Résumé d'auteur)
