ABSTRACT The aim of this work was to evaluate the insecticidal and repellency activity of the essential oil of Cinnamomum camphora var. linaloolifera Y. Fujita (Ho-Sho) and Cinnamomumcamphora (L.) J Presl.var. hosyo (Hon-Sho), against the Sitophilus zeamais in maize grains. The essential oils were obtained by hydrodistillation and analyzed by GC-MS.The insecticidal activity was determined by the toxicity of different concentrations of essential oils during 24 hours of contact with the insects, in the absence of feed substrate. The Bioassays of repellency were conducted with lethal doses (LD50,LD25,and LD12.5) obtained from insecticidal bioassay. In order to compare the treatments the preference index (PI) was employed. The analysis of the essential oils of Cinnamomum camphora leaves indicated 68% of camphor and 9% of linalool for the variation Hon-Sho and 95% of linalool to the variation Ho-Sho. The variation Ho-Sho presented greatest insecticidal activity than the variation Hon-Sho against the Sitophiluszeamais, with LD50 of 0.35 μL/cm2, whereas in the variation Hon-Sho the ratewas 0.48 μL/cm2. However, considering only the concentrations of linalool and camphor of Ho-Sho and Hon-Sho, the lethal doses’ evaluation of these compounds were similar. The values of the preference index ranged from -0.3 to -0.8 for thevariation Ho-Sho and -0.2 to -0.7 for the variation Hon-Sho. The essential oils evaluated in this work showed repellent activity against Sitophiluszeamais in vitro and in trials performed in mini-silos.

AbstractThe chemical composition of the volatile metabolites of Crithmum maritimum harvested from several geographic localities along the Mediterranean coasts was studied by GC and GC-MSD. The major oil constituents were found to be dillapiole, γ-terpinene, sabinene, limo-nene and β-phellandrene. The Western populations were richer in dillapiole, whereas the Southern collections were characterized by increased amounts of thymol methyl ether and y-terpinene. The Italian chemical profiles differentiated by the significant contributions of carvacrol methyl ether and isoterpinolene. The essential oils were also investigated for their insecticidal activity and their repellency against Pheidole pallidula (Nylander) ants and found to possess significant activity.

Main Component

Essential oils of Piper subtomentosum (leaves and inflorescences) and Piper septuplinervium (aerial parts) were analyzed by GC-MS; sixty-three compounds were determined, representing 92.0%, 86.9 %, and 91.8 % of the total relative oil composition of the leaves, inflorescences, and aerial parts, respectively. The most abundant component in the aerial parts and inflorescence oils was α-pinene (27.3%, 21.0%, respectively), and δ-cadinene was the main component of the leaf oil. Insecticidal activity of the essential oils were determined on the Spodoptera frugiperda second instar larvae; the essential oil from the aerial parts of P. septuplinervium was the most active against insect pests (LC50= 9.4 μL/L of air). Statistical analysis by direct Pearson correlation showed that the insecticidal activity of the essential oils was primarily due to camphene and α- and β-pinene. The effect of the oils on the insect life cycle was also evaluated, and in some cases, a delay in growth and inhibition of the oviposition in the females were observed.

(7R)-trans, trans-nepetalactone; a monoterpene iridoid (1) and acetylenic compound named cis-lachnophyllum ester (2) were isolated from the essential oils of Nepeta elliptica and Erigeron annuus, respectively and characterized using a combination of their spectral data  (1D-and 2D-NMR, MS, IR). Compound 1 and 2 were tested for biopesticide activity against mustard aphid, Lipaphis erysimi (Kalt.). Compound 1 exhibited high insecticidal activity towards L. erysimi with LC50 values of 2.18 and 2.73 mg/mL; LT50 values of 15.24 and 17.18 h. Compound 2 also displayed significant insecticidal activity having LC50 values of 0.85 and 4.70 mg/mL; LT50 values of 13.25 and 26.2 h. The activity of compounds 1 and 2 were comparable with synthetic pesticide, monocrotophos used as positive control and thus has potential as natural pesticides for use in economically important crops.
