“…These results agree with a previous report by El-Mancy et al (2021), who formulated the frankincense oil into a nanoemulsion formulation with a droplet size of 17.9 nm and a PDI of 0.2. Furthermore, consistent with findings reported by other researchers on various oils (Abdel-Rheim, (2019); Shi et al, 2012;Al-Mansoori, 2018;Abdel-Rheim, (2019); Abd El-Naby et al, 2022;Molai et al, 2022).…”

“…They discovered excellent effectiveness in suppressing cotton bollworms. In other work, Abd El-Naby et al (2022) found that castor oil nanoemulsion was the most effective, followed by castor bulk oil under laboratory conditions against the fourth instar larvae of the cotton leaf worm S. littoralis . Another potential application of frankincense nanoemulsion was proposed by Al-Mansoori (2018) frankincense nanoemulsion had the strongest inhibitory effects against Listeria monocytogenes as an antibacterial.…”

“…Also, castor oil nanoemulsion demonstrated the highest efficacy when compared to its bulk or standard emulsion, according to Abdel-Raheem (2019) , who studied the effect of castor oil essential oils (bulk and nano phase) on S. littoralis larvae. Abd El-Naby et al (2022) demonstrated that the prepared castor oil nanoemulsion exhibits insecticidal activity followed by castor bulk oil under laboratory conditions against the fourth instar larvae of the cotton leaf worm S. littoralis .…”

Our research shed light on the perspective of formulation technology regarding its responsibility to provide phyto-insecticides that are worthy of research into potential novel applications. There has been an increase in interest in using nanoemulsion as a new formulation in a variety of sectors during the last several decades. Boswellia sacra essential oil (Fam: Burseraceae) from the resin of frankincense trees has been recently proposed as a promising ingredient in a new generation of botanical insecticides. Frankincense nanoemulsion was formulated in 5% ratios comprising frankincense oil, surfactants, and water. A frankincense nanoemulsion was prepared using a high-energy ultra-sonication process and characterized by dynamic light scattering transmission electron microscopy surface tension, viscosity, and zeta potential value. Gas chromatography/mass spectrometry (GC/MS) was used to identify the chemical profiles of frankincense essential oil. Furthermore, insecticidal effects against second instar larvae of the spiny bollworm, Earias insulana, as well as their latent effects on the larvae were studied. In the present study, the formulation was a good nanoemulsion. The surface tension was 53.69, the viscosity was 4.76 cPs, the zeta potential was-10 mV, and the size distribution was 41.30 nm. The polydispersity index (PDI) of the nanoemulsion was found to be 0.26, and the morphology of the frankincense nanoemulsion was visualized in a spherical shape. The main constituents identified in frankincense oil were α-pinene (15.52%); monolinolenin (12.92%); and geranylgeranyl acetate (9.99%). The results showed significant insecticidal activity against the larval stage and considerably decreased the pupation percentage with increasing the volume of the frankincense nanoemulsion. On the other hand, the latent effects of the frankincense nanoemulsion on E. insulana resulted in a higher prolongation of larval and pupal durations as well as a significant reduction in the weight of larvae and pupae of E. insulana. Additionally, frankincense nanoemulsion dramatically influenced the adult emergence percentage. It also caused a significantly lower hatchability percentage compared to the untreated control. The concentrations used and the types of mating combination have a significant effect on the fecundity of E. insulana. This novel frankincense nanoemulsion formulation could be used in strategies to control the spiny bollworm on cotton plants.
