“…citratus EO, Brügger et al 35 reported a lower percentage of geranial (31.5% compared to 45.41%). This variation can be attributed to seasonal fluctuations, differences in temperature at the farms where these plants were cultivated, geographic location, ontogenetic variables, the growth stage of the plant at the time of harvest (pest management), and extraction method 27 , 32 , and all key components were robustly identified and quantified.…”

“…In contrast, temephos showed a lethal time in the range of 60.2-61.3 h, which is longer than that (ranging from 34.3 to 35.8 h) of the least effective EO formulation, C. aurantium EO + geranial (2:1) 10,000 ppm. Previous works 4,27 have already established the potent toxicity of several combined EOs and EO constituents against mosquitoes at most stages in their life cycle, except at the egg stage. The effectiveness of the formulations that combined EO and EO constituents and targeted mosquitoes at the egg stage of their life cycles was first reported in this study.…”

Plant essential oil (EO) is a natural alternative to synthetic chemical insecticides for mosquito control. EOs from Citrus aurantium L., Cymbopogon citratus (Stapf.), and Cinnamomum verum (J. Presl.) were selected for topical assay of their ovicidal activity against Aedes aegypti (Linnaeus) and Aedes albopictus (Skuse). Their efficacy was compared to that of 1% (w/w) temephos. In addition, their non-toxicity against aquatic mosquito predators, Poecilia latipinna and Poecilia reticulata, was tested. Found by GC–MS analysis, the major constituent of C. verum EO was trans-cinnamaldehyde, of C. aurantium EO was d-limonene, and of C. citratus EO was geranial. Both C. verum EO and trans-cinnamaldehyde at a high concentration (30,000 ppm) exhibited high ovicidal activity against Ae. aegypti and Ae. albopictus eggs after 48 h of incubation with an inhibition rate of 91.0–93.0% for C. verum EO and 96.7–95.2% for trans-cinnamaldehyde. The combination of C. verum EO + geranial exhibited the strongest synergistic inhibition activity (100%) against the two mosquito vectors and was five times more effective than temephos. Moreover, they were not toxic to the non-target fishes. As a safe ovicidal agent for mosquito egg control, the combination of C. verum EO + geranial has excellent potential.

The reduction in agricultural production due to the negative impact of insects and weeds, as well as the health and economic burden associated with vector-borne diseases, has promoted the wide use of chemicals that control these “enemies.” However, the use of these synthetic chemicals has been recognized to elicit negative impacts on the environment as well as the health and wellbeing of man. In this study, we presented an overview of recent updates on the environmental and health impacts of synthetic pesticides against agro-pest and disease vectors while exhaustive reviewing the potentials of natural plant products from Zanthoxylum species (Rutaceae) as sustainable alternatives. This study is expected to spur further research on exploiting these plants and their chemicals as safe and effective pesticide entities to minimize the impact of their chemical and synthetic counterparts on health and the environment.
