The essential oil of an Argentine collection of the annual herb Acanthospermum hispidumDC. (Asteraceae), which contains the sesquiterpenoids β-caryophyllene (35.2%), α-bisabolol (11.4%), and germacrene D (11.1%) as major constituents, displayed molluscicidal effects on an adult population of Biomphalaria peregrinaOrbigny (LD5037.8 μg/mL) and produced alteration of the feeding and oviposition behavior of the polyphagous insect Spodoptera frugiperdaSmith when incorporated in the larval diet at 250 μg/g. In addition, a selective antibacterial activity was observed against pathogenic strains of Staphylococcus aureusand Enterococcus faecalis(MICs 62.5 and 125 μg/mL), but was inactive at 125 μg/mL against three beneficial lactic acid bacteria. Synergistic interactions were further validated by FIC index determination of the combination of the antibiotics oxacillin and gentamicin and the essential oil on the four pathogenic strains evaluated. |
