    Insecticidal activity of essential oils onAedes aegypti larvae
    (Wiley, 1998) Jean‐Marie Chantraine; Dominique Laurent; Carolt Ballivian; Gloria Saavedra; Rubén Ibañez; L. Antonio Vilaseca
    The insecticidal activity of essential oils from 52 Bolivian plant species has been evaluated on Aedes aegypti larvae. The active components of essential oils showing an interesting larvicidal effect have been studied. The monoterpenes E-anethol and E-nerolidol were found to be the active principles of the most toxic essential oils. The lethal concentrations (LC50 and LC95) of some essential oils, E-anethol, E-nerolidol and a reference insecticide (Temephos) are given. © 1998 John Wiley & Sons, Ltd.

    Insecticidal activity of essential oils onTriatoma infestans
    (Wiley, 1997) Dominique Laurent; L. Antonio Vilaseca; Jean‐Marie Chantraine; Carolt Ballivan; Gloria Saavedra; Rubén Ibañez
    Sixty-three essential oils isolated from Bolivian plants were tested on Triatoma infestans for ovicidal and larvicidal properties. Three types of test were used: topical application on insects, nymphs on impregnated paper and eggs on impregnated paper. Twenty oils showed an interesting activity on nymphs and eggs when the impregnated paper tests were used. These tests proved to be the most sensitive and were therefore chosen for studying the action of a dozen terpenes present in those active essential oils. © 1997 John Wiley & Sons, Ltd.

    Repellent activity of essential oils on Triatoma infestans
    (Thieme Medical Publishers (Germany), 2008) L. Antonio Vilaseca; Dominique Laurent; Carolt Ballivian; J-M Chantraine; Rubén Ibañez
    Chagas disease is a parasitic disease caused by Trypanosoma cruzi, transmitted to humans by some Triatominae species, affecting an estimated in 28 million people in Latin America [1]. Triatoma infestans is the most widespread vector in South America, extending from the Peruvian highlands to the northeast Brazilian regions, including the plains of Argentina [2].
