| Resumo: |
The development of natural insecticides would help to decrease the negative impact of synthetic insecticides. Fumigant toxicity of essential oil of Tagetes filifolia Lag (Asterales: Asteraceae) and its major compounds were evaluated against Tribolium castaneum Herbst (Coleoptera: Tenebrionidae). The essential oils were analyzed by gas chromatography-mass spectrometry. The essential oil and (E)-anethole were the most toxic at 24 h against adult insects (CL50 = 2.4 y 2.6 µL/mL water, respectively). Changes in the products of lipid peroxidation were evidenced by an increase in malondialdehyde content. Acetylcholinesterase activity in vitro, of T. castaneum adults, was also reported. (E)-anethole and estragole showed similar acetylcholinesterase inhibition (54 and 63%, respectively at 5 mM). The present study constitutes one of the first contributions to understanding the relationship between the insecticidal action of essential oil and oxidative stress.
