Abstract

The biological activity of plant extracts derived from Lippia alba, Mentha x piperita, Ocimum basilicum, Quassia amara y Schinus molle, against the red flour beetle Tribolium castaneum Herbst (Coleoptera: Tenebrionidae) was investigated in the laboratory using a simple method to determine insect repellency and toxicity. Botanicals were highly repellent to the beetles with overall effectivity in the range of 77-96 %. Extracts applied on wheat grains were slightly toxic to the insects and caused 20-40 % mortality after 7 days exposure.
