“…Similarly, Rizzo et al 46 reported insecticidal potential of essential oils of Thymbra spicata L., Ocimum gratissimum L., Pimpinella anisum L., and Trachyspermum ammi (L.) Sprague rich in monoterpenes thymol, p-cymene, γ-terpinene, ( E )-anethole, and carvacrol against adults of olive fruit fly, Bactrocera oleae (Rossi). Basij et al 53 too documented larvicidal activity of γ-terpinene and other monoterpenes (thymol and p-cymene) from Carum copticum L. against Asiatic rice borer, Chilo suppressalis Walker. Abdelgaleil et al 17 attributed the lethality of monoterpenes to their neurotoxic effects on AChE, GABA, octopamine receptors, voltage-gated sodium channels, and glutamate-gated chloride channels of the target pest.…”

Abstractγ-Terpinene, a monoterpene widely present in essential oils of many medicinal and aromatic plants with numerous biological properties, was evaluated for its insecticidal activity against melon fruit fly, Zeugodacus cucurbitae (Coquillett). Different concentrations (5, 25, 125, 625, and 3125 ppm) of γ-terpinene along with control were fed to larvae of melon fly. The number of pupae formed and adults emerged declined significantly after treatment. Morphologically deformed adults and pupae were also observed. The developmental duration too prolonged in treated larvae. Food assimilated, mean relative growth rate, larval weight gain, and pupal weight also declined. In the larvae treated with LC30 and LC50 concentrations, there was a decline in the titers of phenoloxidase and total hemocyte count, and variations were observed in the differential hemocyte count, suggesting an immunosuppressive effect of γ-terpinene on melon fly. Both concentrations also led to an increase in the apoptotic and necrotic cells as well as decrease in the viable hemocytes in the circulating hemolymph of treated larvae. Comet parameters (tail length, % tail DNA, tail moment, and olive tail moment) of γ-terpinene fed larvae increased significantly. Given the observed effects of γ-terpinene on normal developmental and nutritional physiology, its immunosuppressive properties, and its potential for genome damage, it can be considered for incorporation into integrated pest management strategies for controlling Z. cucurbitae.

“…The effectiveness of insecticidal activity was further enhanced by combining thymol with γterpinene or p-cymene. Among these compounds, thymol appeared as a promising biopesticide for controlling C. suppressalis populations, demonstrating insecticidal properties and compatibility with other components possessing high acetylcholinesterase inhibition capabilities [64].…”

Essential oils (EOs) are highly concentrated and volatile blends of nonpolar substances, are derived from aromatic plant components and comprise terpenes, terpenoids and phenylpropanoids, exhibiting diverse biological and pharmacological properties. The burgeoning pet industry is interested in EOs as a potential solution for common health issues in domestic animals, particularly in addressing antimicrobial resistance. The present study summarizes the composition, properties, benefits, safety considerations, and effects of EOs on pets and animals. The applications of EOs range from antimicrobial effects to antioxidant, anti-inflammatory, and anticancer activities etc. Furthermore, EOs are used extensively in various industries, including beauty care products, detergents, and fragrances. The chemical constituents of EOs, exemplified by eucalyptus EO and rosemary EO, highlight their distinct aromatic profiles and potential benefits. Nevertheless, understanding the chemical makeup of EOs is fundamental in assessing their potential impacts on biological systems. Safety considerations, including potential toxicity, are essential when incorporating EOs into animal care routines. The feed additives incorporating EOs have shown promise in influencing gut microbiota balance, reducing inflammation, and acting as antioxidants. However, cautious application is paramount, considering the potential risks associated with high doses or multiple administrations. Preliminary studies suggest low toxicity levels, but further research is required to evaluate the safety of EOs. Though studies reported the beneficial effects of EOs on pets and animals, further research is needed to validate the findings in real-world conditions. The paper also discussed the regulatory considerations and future perspectives on applying EOs in veterinary medicine.

The aim of this research is to develop a composite antibacterial film for food packaging using low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), polyethylene-graft-maleic anhydride (PE-g-MA), and incorporating chitosan (CS) particles onto which ajwan essential oil (AEO) is adsorbed. The films were characterized using various techniques, including Fourier-transform infrared spectroscopy (FTIR), Gas chromatography/mass spectroscopy (GC-MS), X-ray diffraction (XRD), tensile testing, oxygen transmission rate (OTR), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), and antibacterial assays. FTIR results confirmed the presence of CS and/or AEO in the films. Mechanical testing indicated a decrease in tensile strength and an increase in elongation at break with the addition of AEO, while CS reduced elongation. In the sample containing only 7.5% chitosan (PE-7.5-0), the oxygen permeability was reduced to 910 cm 2 /m 2 ·day·bar due to the presence of CS. However, the inclusion of AEO in the sample (PE-0-10) increased the oxygen permeability to 2200 cm 2 /m 2 ·day·bar, which is higher than that of the control sample (PE-0-0) with an oxygen permeability of 1680 cm 2 /m 2 ·day·bar. The antibacterial activity results demonstrated a synergistic inhibitory effect of CS and AEO. Data from GC-MS and inhibition zone (IZ) tests indicated that while chitosan alone does not exhibit significant antibacterial activity due to its incorporation in the bulk of the film, its combination with AEO enhances antibacterial efficacy. This enhancement occurs as the oil is adsorbed and protected from evaporation during the film formation process. Overall, the findings from this research suggest that the composite film PE-7.5-10, which possesses suitable mechanical properties and significant antibacterial activity, could be an effective candidate for food packaging applications.
