Volatile chemical composition of Piper sancti-felicis Trel essential oil and its biocidal action against Tribolium castaneum (Herbst)

Abstract

This research assessed the fumigant activity of the essential oil from Piper sancti-felicis Trel and five of its components on the Tribolium castaneum (Herbst) biological model. Hydrodistillation was used for extraction of the essential oil, with separation and identification of the compounds through gas chromatography coupled to mass spectrometry (GC-MS). The fumigant was evaluated through gas dispersion on the T. castaneum. The majority compounds found in the EO were b-nerolidol (15.4%), 3-carene (14.9%), p-cymene (9.1%), spathulenol (8.2%), a-cubebene (6.2%) and calamenene (5.2%). Piper sancti-felicis displayed fumigant activity with a LC50 = 108.5 μg L-1 air, and other individual monoterpenes tested such as α-terpinolene (LC50 = 110.1 μg L-1 air), p-cymene (LC50 = 120.3 μg L-1 air), 3-carene (LC50 = 130.6 μg L-1 air), (R) -limonene (CL50 = 189.6 μg L-1 air), and a-pinene (LC50 = 213.1 μg L-1 air), were significantly less toxic than methyl pyrimiphos used as a positive control, CL50 = 87.4 μg L-1 air. The essential oil of P. sancti-felicis can be considered as a natural source of biocides

“…Other compounds similar to those in Figure 6, were found as major compounds in Kyllinga pumila Michx (Cyperaceae) EO (Z-caryophyllene, E-caryophyllene and germacrene D with 11.3, 5.6 and 7.1%, respectively) (Jaramillo-Colorado, Martínez-Cáceres, & Duarte-Restrepo, 2016). Spathulenol was also identified in Piper sancti-felicis Trel (Piperaceae) EO (8.2%), with a similar amount to C. concinna (7.33%) (Medrano-Ochoa et al, 2021). Both essential oils presented insecticide/repellent activity against Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), an insect considered a pest in stored cereals and other foods.…”

Insecticidal activity of the essential oil ofPiper corcovadensisleaves and its major compound (1‐butyl‐3,4‐methylenedioxybenzene) against the maize weevil,Sitophilus zeamais

“…Among the alternatives are inert powders, such as diatomaceous earth, and products derived from plants, such as extracts, essential oils and lectins 12–18 . Extracts and essential oils from plants of the Piperaceae family are promising for pest and vector control 19,20 . The genus Piper is one of the most important members of this family, and essential oils from plants of this genus contain insecticidal compounds such as safrole 21 .…”
