Chemical Characterization and Application of the Essential Oils from Chenopodium ambrosioides and Philodendron bipinnatifidum in the Control of Diabrotica speciosa (Coleoptera: Chrysomelidae)

Abstract

The compositions of essential oils from Chenopodium ambrosioides L. and Philodendron bipinnatifidum Schott were determined, and their potential effects on the nutrition and mortality of Diabrotica speciosa were studied. The extraction of the oils was performed by hydrodistillation (2 h) using a modified Clevenger apparatus and the oils were subsequently subjected to analysis by gas chromatography/flame ionization detector (CG/FID) and gas chromatography/mass spectrometry (GC-MS). A completely randomized design with five treatments and four replications was adopted. The bean plants were sprayed with solutions of the oils dissolved in aqueous Tween 80 solutions at concentrations of 0 (water + Tween 80), 0.5%, 1.0%, 1.5% and 2.0% and then furnished to the insects with no choice available. Seven days after the application, the percentage of leaves with injury, degree of defoliation, the preference index for consumption and the percent of mortality of insects were evaluated. Neither of the essential oils caused a reduction in foliar injury, but antifeeding activity was observed, causing reduced feeding and increasing the mortality of adult D.

<b>Essential oil from <i>Chenopodium ambrosioides</i> L.: secretory structures, antibacterial and antioxidant activities

“…The principal constituents found were α-terpinene, pcymene and trans-ascaridole. The remaining components identified were found in percentages ≤0.5% (Santiago et al, 2014).…”

Comparative Analysis of the Composition and Active Property Evaluation of Certain Essential Oils to Assess their Potential Applications in Active Food Packaging

“…Bozin et al characterized Lamiaceae species and the antimicrobial and antioxidant activities of the oils of Ocimum basilicum L., Origanum vulgare L., and Thymus vulgaris L. [ 6 ], and the chemical constituents of four populations of Piper aduncum L. from Distrito Federal, Brazil [ 7 ], were identified. Many other essential oils have been characterized, namely, sweet lime ( Citrus limetta Risso) [ 8 ], Chenopodium ambrosioides , Philodendron bipinnatifidum [ 9 ], cinnamon oil, eucalyptus oil, lemongrass oil, peppermint oil, citronella oil, turpentine oil [ 10 ], citronella oil [ 11 ], Tithonia diversifolia (Hemsl.) A.…”

Volatile oils from Philodendron meridionale Buturi & Sakur: chemical composition and in vitro effect against Ctenocephalides felis and leukemia cells

“…Studies on the composition of volatile oils from Philodendron plants are still scarce. Limonene and copaene have been found in some other species of this genus, while caryophyllene has been observed in all of those studied taxa with some different stereochemical orientations and concentrations (Viana, Andrade-Neto & Pouliquen, 2002;Bezerra et al, 2002;Ottobelli et al, 2011;Castellar et al, 2013;Santiago et al, 2014;Bacchus et al, 2015;Joffard et al, 2017). Germacrene has also been investigated by Silva et al (2016) for Philodendron maximum K. Krause, as well as by Joffard et al (2017) for…”

“…Alliance et al (2017) investigated the potential effect of essential oils from the root of Philodendron deflexum Poepp on larvae of Aedes aegypti Linnaeus and Anopheles albirtasis Lynch-Arribálzaga. Santiago et al (2014) described the insecticidal activity of essential oils from the roots of Philodendron bipinnatifidum Schott on Diabrotica speciose. Germar and Silva et al (2016) reported the antibacterial activity of the Philodendron goeldii essential oil G. M Barroso against Corynebacterium glutamicum.…”
