“…However, our study revealed that the NEs developed in this research displayed enhanced and prolonged insecticidal activity compared to other NEs formulated with EO or synthetic insecticides. Almadiy et al 52 evaluated the residual activity of NEs formulated with Deverra tortuosa DC (Apiales, Apiaceae) EO and Tween 80 in treated grains at LC 95 values against Callosobruchus maculatus Fabricius (Coleoptera, Chrysomelidae), and these NEs showed a lethal time 50 (of 29.4 ± 2.4 days). Faustino et al 53 evaluated the toxicological effect of NEs of Protium heptaphyllum Marchand (Sapindales, Burseraceae) and Tween 80 against Aedes aegypti Meigen (Diptera, Culicidae), and at 20 μg/mL, these nanosystems caused mortality for 96 h. Moreover, NEs formulated with Cinnamomum zeylanicum J.Presl (Lauraceae) or Myrtus communis L. (Myrtales, Myrtaceae) EO (0.5% w/w) and Tween 80 and Span 20 showed larvicidal activity for 8 days against Anopheles stephensi Liston (Diptera, Culicidae).…”

BackgroundThe development of novel and ecofriendly tools plays an important role in insect pest management. Nanoemulsions (NEs) based on essential oils (EOs) offer a safer alternative for human health and the environment. This study aimed to elaborate and evaluate the toxicological effects of NEs containing peppermint or palmarosa EOs combined with β‐cypermethrin (β‐CP) using ultrasound technique.ResultsThe optimized ratio of active ingredients to surfactant was 1:2. The NEs containing peppermint EO combined with β‐CP (NEs peppermint/β‐CP) were polydisperse with two peaks at 12.77 nm (33.4% intensity) and 299.1 nm (66.6% intensity). However, the NEs containing palmarosa EO combined with β‐CP (NEs palmarosa/β‐CP) were monodisperse with a size of 104.5 nm. Both NEs were transparent and stable for 2 months. The insecticidal effect of NEs was evaluated against Tribolium castaneum and Sitophilus oryzae adults, as well as Culex pipiens pipiens larvae. On all these insects, NEs peppermint/β‐CP enhanced pyrethroid bioactivity from 4.22‐ to 16‐folds while NEs palmarosa/β‐CP, from 3.90‐ to 10.6‐folds. Moreover, both NEs maintained high insecticidal activities against all insects for 2 months, although a slight increase of the particle size was detected.ConclusionThe NEs elaborated in this work can be considered as highly promising formulations for the development of new insecticides. © 2023 Society of Chemical Industry.

“…Almadiy (2021) [76] reported a superior bioactivity of a nanoemulsion of Achillea biebersteinii on the red flour beetle when compared with the free essential oil and its main monoterpenes; likewise, Suresh et al (2020) found that the sea fennel in nanoemulsion was close to twice as bioactive than its free form [77]. In the same way, various essential oil nanoemulsions have demonstrated to be more effective against agriculture and stored food pests than the free essential oil, this is appreciated in a lower concentration requirement to neutralized 50% (LC 50 ) of arthropod population in toxicity assays [78][79][80].…”

Pest control is a main concern in agriculture. Indiscriminate application of synthetic pesticides has caused negative impacts leading to the rapid development of resistance in arthropod pests. Plant secondary metabolites have been proposed as a safer alternative to conventional pesticides. Monoterpenoids have reported bioactivities against important pests; however, due to their high volatility, low water solubility and chemical instability, the application of these compounds has been limited. Nanosystems represent a potential vehicle for the broad application of monoterpenoids. In this study, an 1,8-cineole nanoemulsion was prepared by the low energy method of phase inversion, characterization of droplet size distribution and polydispersity index (PDI) was carried out by dynamic light scattering and stability was evaluated by centrifugation and Turbiscan analysis. Fumigant bioactivity was evaluated against Tetranychus urticae, Rhopalosiphum maidis and Bemisia tabaci. A nanoemulsion with oil:surfactant:water ratio of 0.5:1:8.5 had a droplet size of 14.7 nm and PDI of 0.178. Formulation was stable after centrifugation and the Turbiscan analysis showed no particle migration and a delta backscattering of ±1%. Nanoemulsion exhibited around 50% more bioactivity as a fumigant on arthropods when compared to free monoterpenoid. These results suggest that nanoformulations can provide volatile compounds of protection against volatilization, improving their bioactivity.

“…Studies by various researchers have also reported that monoterpenes have antiseptic, anti-cancer, antibacterial, and antifungal properties ( Scariot et al., 2021 ; Silva et al., 2021 ). Various monoterpene types are used in foods as a flavoring and fragrant additive ( Li et al., 2021 ; Wackett, 2021 ; Ignea et al., 2022 ), and in agriculture and animal husbandry due to their insecticidal and pesticide effects ( Alam et al., 2022 ; Almadiy et al., 2022 ; Song et al., 2022 ).…”

Plants are the sources of many bioactive secondary metabolites which are present in plant organs including leaves, stems, roots, and flowers. Although they provide advantages to the plants in many cases, they are not necessary for metabolisms related to growth, development, and reproduction. They are specific to plant species and are precursor substances, which can be modified for generations of various compounds in different plant species. Secondary metabolites are used in many industries, including dye, food processing and cosmetic industries, and in agricultural control as well as being used as pharmaceutical raw materials by humans. For this reason, the demand is high; therefore, they are needed to be obtained in large volumes and the large productions can be achieved using biotechnological methods in addition to production, being done with classical methods. For this, plant biotechnology can be put in action through using different methods. The most important of these methods include tissue culture and gene transfer. The genetically modified plants are agriculturally more productive and are commercially more effective and are valuable tools for industrial and medical purposes as well as being the sources of many secondary metabolites of therapeutic importance. With plant tissue culture applications, which are also the first step in obtaining transgenic plants with having desirable characteristics, it is possible to produce specific secondary metabolites in large-scale through using whole plants or using specific tissues of these plants in laboratory conditions. Currently, many studies are going on this subject, and some of them receiving attention are found to be taken place in plant biotechnology and having promising applications. In this work, particularly benefits of secondary metabolites, and their productions through tissue culture-based biotechnological applications are discussed using literature with presence of current studies.
