Essential Oil from Pimenta pseudocaryophyllus (Myrtaceae) Leaves and Its Major Compounds Against the Mexican Bean Weevil
Eco-friendly strategies, including botanical insecticides, can contribute to stored products Integrated Pest Management (IPM) programs as alternatives to chemical insecticides. Thus, this study investigated the chemical composition and the fumigant insecticidal activity of the essential oil (EO) from Pimenta pseudocaryophyllus (Myrtaceae) leaves against adults of Mexican bean weevil, Zabrotes subfasciatus (Coleoptera: Chrysomelidae: Bruchinae), an important insect pest of stored beans in tropical conditions. In addition, the contribution of EO’s major compounds and binary mixtures on overall fumigant insecticidal activity against this pest was also assessed. Based in the GC-MS analysis, the phenylpropanoids chavibetol (39.60%) and methyl eugenol (9.10%) and the monoterpenoids 1,8-cineole (13.89%) and terpinolene (8.19%) were identified as major components. After 72 h of exposure, the EO showed promising insecticidal fumigant activity against Z. subfasciatus with a strong interaction effect of sex (LC50: 280.17 and 86.63 µL L−1 of air, respectively for females and males). When tested at their relative concentration in the crude EO, the phenylpropanoids chavibetol, methyl eugenol and the monoterpenoid 1,8-cineole as well as their binary mixtures caused the total mortality of exposed weevils, being equitoxic to a phosphine-based formulation used as a positive control. Thus, the EO from P. pseudocaryophyllus leaves is a promising fumigant insecticide to Z. subfasciatus management and its major compounds chavibetol, methyl eugenol and 1,8-cineole may be used to develop efficient and inexpensive artificial blends to IPM of stored beans.
期刊介绍:
Gesunde Pflanzen publiziert praxisbezogene Beiträge zum Pflanzenschutz in Landwirtschaft, Forstwirtschaft, Gartenbau und öffentlichem Grün und seinen Bezügen zum Umwelt- und Verbraucherschutz sowie zu Rechtsfragen.
Das Themenspektrum reicht von der Bestimmung der Schadorganismen über Maßnahmen und Verfahren zur Minderung des Befallsrisikos bis hin zur Entwicklung und Anwendung nicht-chemischer und chemischer Bekämpfungsstrategien und -verfahren, aber auch zu Fragen der Auswirkungen des Pflanzenschutzes auf die Umwelt, die Sicherung der Ernährung sowie zu allgemeinen Fragen wie Nutzen und Risiken und zur Entwicklung neuer Technologien.
Jedes Heft enthält Originalbeiträge renommierter Wissenschaftler, aktuelle Informationen von Verbänden sowie aus der Industrie, Pressemitteilungen und Personalia.
Damit bietet die Zeitschrift vor allem Behörden und Anwendern im Agrarsektor und Verbraucherschutz fundierte Praxisunterstützung auf wissenschaftlichem Niveau.
