Abstract

The essential oils of Cedrus atlantica (Endl.) (Pinales: Pinaceae), Mentha x piperita L. (Lamiales: Lamiaceae), and Santalum paniculatum L. (Santalales: Santalaceae), were evaluated for their bioactivity on red flour beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae). The most pharmacologically effective oil for this beetle species was that of M. piperita followed by C. atlantica and S. paniculatum. Mentha piperita provided about 74% repellency (at 1 d) to adults, whereas larval fumigant mortality was nearly 50% at 8 h of exposure. The greatest apparent reduction of egg hatch occurred with S. paniculatum (76%) when compared with M. piperita (25%) after 15 d. However, we believe that all 3 essential oils could be helpful for controlling red flour beetles to some degree. After recording bioactivity for all essential oils tested, each was subjected to gas chromatography-mass spectrometry (GC-MS) analysis to identify its chemical components. Further studies should be conducted to test the bioactivity of the individual chemical components of these oils for T. castaneum.

 

Resumen

Los aceites esenciales de Cedrus atlantica (Endl.) (Pinales: Pinaceae), Mentha x piperita L. (Lamiales: Lamiaceae) y Santalum paniculatum L. (Santalales: Santalaceae) fueron evaluados por su bioactividad sobre el escarabajo rojo de la harina, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae). El aceite más farmacológicamente eficaz para esta especie de escarabajo fue el de M. piperita seguido de C. atlantica y S. paniculatum. Mentha piperita proporcionó aproximadamente 74% de repelencia (a 1 dia) a los adultos, mientras que la mortalidad de larvales expuestas a los fumigantes fue de casi el 50% a las 8 horas de exposición. La mayor reducción de huevos sucedio con S. paniculatum (76%) en comparación con M. piperita (25%) después de 15 días. Sin embargo, creemos que los 3 aceites esenciales podrían ser útiles para controlar los escarabajos rojos de la harina hasta cierto punto. Después de registrar la bioactividad de todos los aceites esenciales analizados, cada uno de ellos fue sometido a un análisis de cromatografía de gases y espectrometría de masas (GC-MS) para identificar sus componentes químicos. Se deben realizar más estudios para probar la bioactividad de los componentes químicos individuales de estos aceites para T. castaneum.
