“…have been reported to contain high levels of 1,8-cineol, a terpenoid well-documented as an antibacterial agent 24,25 and it is likely that this compound contributes to the activity reported herein. This compound has also been reported to be toxic 26,27 and may account for the toxicity reported in our study.…”

Introduction: Eucalyptus baileyana (Bailey's stringy bark) and Eucalyptus major (Queensland grey gum) have been previously used as antimicrobials against a variety of ailments. This study evaluated the effectiveness of E. baileyana and E. major as inhibitory agents against Shewanella putrefaciens, a bacterium widely associated with fish spoilage. Methodology: E. baileyana and E. major extracts were prepared using the leaves of each plant with methanol or water as the extraction solvent. Growth inhibition and minimal inhibitory concentrations were determined against S. putrefaciens through disc diffusion assays. MIC values were subsequently quantified to evaluate the extracts efficacies as antibacterial agents. Finally, the toxicity of each extract was determined using the Artemia franciscana nauplii bioassay. Results: E. baileyana aqueous and methanolic leaf extracts inhibited the growth of S. putrefaciens in the disc diffusion assay, with MIC values of 1411 and 1221 μg/mL respectively. Similarly, E. major leaf extracts also showed growth inhibition of S. putrefaciens, with MIC values of 1686 μg/mL for the aqueous extract, and 1160 μg/mL for the methanolic extract. However, toxicity studies of the extracts revealed that all extracts were toxic and likely unsuitable for human consumption (LC 50 values 455-1146 μg/mL) as determined by the Artemia franciscana bioassay. Conclusion: While the E. baileyana and E. major leaf extracts were effective in preventing microbial growth, given their relatively high levels of toxicity, they would not be suitable for use as a preservative in the prevention of fish spoilage. However, the antibacterial capacity of the extracts indicates that the extracts may show promise as a surface disinfectant, and this should be investigated further.

Essential oils are biologically and environmentally safe pesticidal compounds yielded from aromatic plants. Spices are important sources of essential oils, and they are widely used in the medicine, food, and various other industries. Among the different spices, Allspice (Pimenta dioica) is underexplored in terms of its biological efficacy and a limited number of studies are available on the chemical composition of Allspice essential oil (AEO); thus, the present study evaluated the larvicidal property, the repellency, and the fumigant toxicity against common pests of stored products of AEO. AEO was found to inhibit the survival of larvae of such vectors as Aedis, Culex, and Armigeres species. Further, AEO was found to exert repellant effects against the pests of such stored products as Sitophilus, Callosobruchus, and Tribolium. Similarly, the fumigant toxicity was found to be high for AEO against these species. The contact toxicity of AEO was high against Sitophilus and Callosobruchus. Apart from that, the essential oil was found to be safe against a non-target organism (guppy fishes) and was found to be non-genotoxic in an Allium cepa model. Overall, the results of the present study indicate that the essential oil from Allspice could be used as an environmentally safe larvicidal and biopesticidal compound.

“…The major constituents of three essential oils are 1,8cineole (52.8 %) for rosemary (El-Massry et al 2008), aliphatic acids, and phenolic compounds for vanilla (Pérez-Silva et al 2006), and carvone (48.60%) for spearmint. These chemicals are all reportedly toxic to insects (Tripathi et al 2003;Tripathi et al 2009;Bullangpoti et al 2018). From the statistical analysis, vanilla oil proved to be most potent, followed by spearmint and rosemary.…”

Abstract. Laojun S, Chaiphongpachara T. 2020. Comparative study of larvicidal activity of commercial essential oils from aromatic rosemary, vanilla, and spearmint against the mosquito Aedes aegypti. Biodiversitas 21: 2383-2389. Dengue fever is a dangerous mosquito-borne viral disease of humans. This disease is caused by dengue virus, a member of the genus Flavivirus of the family Flaviviridae. The Aedes aegypti mosquito is a principal vector for this virus. To control Ae. aegypti populations, there is extensive focus on larval eradication, because breeding sites are often close to human populations, especially man-made containers. The objective of this research was to evaluate the efficacy of commercial essential oils from rosemary (Rosmarinus officinalis), vanilla (Vanilla planifolia), and spearmint (Mentha spicata) with regard to larvicidal activity against Ae. aegypti larvae after 24 and 48-hours of exposure in the laboratory. The results showed highly efficacious larvicidal activity, with median lethal doses (LC50) of 0.23, 0.10, and 0.12 ppm after 24-hour exposure to commercial rosemary, vanilla, and spearmint oil, respectively. The results of this study will be useful for the control of a common dengue vector and may replace the use of pesticides that may have broad environmental impacts.
