“…The structure of the delivery system includes the encapsulation of active compounds inside, a nanoparticulate polymeric shell, adsorption onto the nanoparticle surface, attachment onto the nanoparticle core via ligands, and entrapment within the polymeric matrix [77]. The properties of these various types of nanocarrier formulations are known to enhance the efficacy and efficiency of biopesticides against insect pests, i.e., a nanoemulsion loaded with essential oil from various plants products [78][79][80], plant extracts loaded in micelle with a hydrophobic core [58] and liposome with a hydrophilic core [81], as shown in Figure 2. Recently, materials from natural polysaccharides, proteins, alginates, silica, and other types of polymers have been utilized as nanoparticle encapsulants, such as chitosan, zein, gum arabic, and silica nanoparticles [31,78,82].…”

The productivity of vegetable crops is constrained by insect pests. The search for alternative insect pest control is becoming increasingly important and is including the use of plant-derived pesticides. Plant-derived pesticides are reported as effective in controlling various insect pests through natural mechanisms, with biodegradable organic materials, diverse bioactivity, and low toxicity to non-target organisms. An antifeedant approach for insect control in crop management has been comprehensively studied by many researchers, though it has only been restricted to plant-based compounds and to the laboratory level at least. Nano-delivery formulations of biopesticides offer a wide variety of benefits, including increased effectiveness and efficiency (well-dispersion, wettability, and target delivery) with the improved properties of the antifeedant. This review paper evaluates the role of the nano-delivery system in antifeedant obtained from various plant extracts. The evaluation includes the research progress of antifeedant-based nano-delivery systems and the bioactivity performances of different types of nano-carrier formulations against various insect pests. An antifeedant nano-delivery system can increase their bioactivities, such as increasing sublethal bioactivity or reducing toxicity levels in both crude extracts/essential oils (EOs) and pure compounds. However, the plant-based antifeedant requires nanotechnological development to improve the nano-delivery systems regarding properties related to the bioactive functionality and the target site of insect pests. It is highlighted that the formulation of plant extracts creates a forthcoming insight for a field-scale application of this nano-delivery antifeedant due to the possible economic production process.

“…It is also important to focus on an appropriate formulation of the botanical insecticide, since the latter can significantly increase the biological efficacy of an EO, thus reducing the needed application concentration. For example, a nanoformulation of the EO from Mentha spicata L. (Lamiales: Lamiaceae) increased its efficacy against Culex pipiens L. (Diptera: Culicidae) and M. domestica by more than 71 and 52%, respectively [70]. The prospects of green microand nano-emulsions, increasing the EOs efficacy as well as safety, have also been confirmed by other studies [22,83].…”

“…Indeed, according to Pavela [68], EO-based mosquito larvicides achieving LC 50 values < 50 µL L −1 can be considered promising for further development of mosquitocidal products. Further efforts to boost the EO stability and efficacy in the field are still needed [22] to allow its real-world use, with special reference to the encapsulation in nanoemulsions to boost bioactivity and stability in the field [69,70]. Regarding M. domestica, a different toxicity of the R. segetum flower EO was found on male and female flies, calculating LD 50 values of 10.5 and 50.8 µg adult −1 , respectively (LD 90 = 75.2 and 147.5 µg adult −1 , respectively), with not overlapping 95% confidence intervals (Table 2).…”

Chemical Composition and Broad-Spectrum Insecticidal Activity of the Flower Essential Oil from an Ancient Sicilian Food Plant, Ridolfia segetum

Several species of the family Apiaceae are aromatic herbs that produce essential oils usable on an industrial scale for pharmaceutical, cosmetic, and food purposes. In particular, some essential oils, such as green insecticides for example, may replace synthetic insecticides, keeping most of their efficacy and avoiding environmental pollution or human poisoning. In the present study, we explored the insecticidal potential of Ridolfia segetum (L.) Moris essential oil (EO) against three different pests: Culex quinquefasciatus Say, Musca domestica L., and Spodoptera littoralis (Boisduval). For this purpose, the EO was obtained by hydrodistillation of flowers and its composition was achieved by gas chromatography/flame ionization detection (GC/FID) and gas chromatography/mass spectrometry (GC/MS). This EO was rich in α-phellandrene (49.3%), β-phellandrene (9.2%), terpinolene (20.7%), and piperitenone oxide (5.9%). Concerning the mosquitocidal efficacy, the EO showed noteworthy toxicity against C. quinquefasciatus 3rd instar larvae, with a LC50 = 27.1 µL L−1 and LC90 = 42.5 µL L−1. Regarding M. domestica, a different toxicity of the R. segetum EO was found on male and female flies, calculating LD50 values of 10.5 and 50.8 µg adult−1, respectively. The EO was also toxic to S. littoralis 3rd instar larvae, achieving LD50 and LD90 values of 37.9 and 99.6 µg larva−1, respectively. Overall, this flower EO, extracted from a traditional Sicilian food plant, merits further investigation for the development of green insecticide formulations to be used in real world conditions, pending a careful assessment of non-target toxicity on beneficial organisms.

“…In addition, EOs can cause dysregulation of pheromones, hormones, and biochemical and physiological dysfunctions. EOs can also act by inhibiting insect growth and inhibiting food intake (Mohafrash et al 2020).…”

Rosmarinus officinalis essential oil incorporated into nanoparticles as an efficient insecticide against Drosophila suzukii (Diptera: Drosophilidae)

The effective control of an insect pest such as Drosophila suzukii (Diptera: Drosophilidae) has been challenging because its attack on red fruits can cause losses in production of up to 80% worldwide. The objective of this work was to extract and characterise the essential oil from rosemary (Rosmarinus officinalis), produce and characterise nanoparticles incorporated with this essential oil, evaluate the in vivo insecticide activity of free and nanoencapsulated essential oil against D. suzukii, and evaluate the effect of that oil on the enzyme acetylcholinesterase. The nanoparticles produced with the essential oil from rosemary had a particle size and surface charge of 236.6 nm and À11.8 mV, respectively. According to the FTIR data, the essential oil was incorporated into the polymeric matrix of poly(ε-caprolactone). Through in vivo toxicity analysis, the free and nanoencapsulated essential oils were found to possess insecticidal activity, with an LD 50 close to 9.1 g/L. The maximum anticholinesterase activity for the essential oil was 75% at a concentration of 0.10 mg/mL. The incorporation of the essential oil from R. officinalis into biodegradable nanoparticles of poly(ε-caprolactone) potentiated and prolonged its in vivo insecticidal activity against D. suzukii.
