“…Similar to the above, larvicidal properties of the nanoemulsion increased significantly with decreasing droplet size ( 18 ). Previous studies had shown good results of new nanoformulations as larvicides ( 11 ), although all prepared nanoformulations had no similar effects. It is possible that different effects can be observed among different plant natural products and their formulations.…”

“…The formulated nanoemulsion showed 32% better larvicidal effect as compared to the essential oil, the residual effect of the formulation was 3 days.

“…The use of natural products is an interesting approach in this regards. Today, there are loads of studies and recommendations on plant extracts and essential oils as larvicides, insecticides and repellents ( 10 , 11 ). Extracts and essential oils (EOs) are biocompatible and have minimum toxic effects on non-target organisms.…”

Background: Extensive use of chemical larvicides to control larvae, has led to resistance in vectors. More efforts have been conducted the use of natural products such as plant essential oils and their new formulations against disease vectors. Nanoformulation techniques are expected to reduce volatility and increase larvicidal efficacy of essential oils. In this study for the ﬁrst time, a larvicide nanoemulsion from the essential oil of Acroptilon repens was developed and evaluated against Anopheles stephensi larvae under laboratory conditions. Methods: Fresh samples of A. repens plant were collected from Urmia, West Azarbaijan Prov- ince, Iran. A clevenger type apparatus was used for extracting oil. Components of A. repens essential oil (AEO) were identiﬁed by gas chromatography–mass spectrometry (GC–MS). All larvicidal bioassay tests were performed according to the method recommended by the World Health Organization under laboratory condition. Particle size and the morphologies of all pre- pared nanoformulations determined by DLS and TEM analysis. Results: A total of 111 compounds were identiﬁed in plant. The LC50 and LC90 values of AEO calculated as 7 ppm and 35 ppm respectively. AEO was able to kill 100% of the larvae in 4 days. Conclusion: The nanoemulsion of AEO showed a weak effect on the larvar mortality. It may therefore be suggested that this kind of nanoemulsion is not appropriate for the formulation as a larvicide. It is important to screen native plant natural products, search for new materials and prepare new formulations to develop alternative interventions with a long-lasting impact.

“…The small size of the particles allows them to be delivered directly to biological targets and protects the encapsulated compounds from degradation and volatilization by increasing their half-lives with a controlled release rate ( Rahman et al, 2019 ). Cinnamomum zeylanicum oil nanoemulsion showed potential larvicidal effect against Anopheles vector ( Firooziyan et al, 2021 ). Bio-fabricated sardine fish scale silver nanoparticles effectively killed the Anopheles larvae ( Murugan et al, 2021 ).…”

There is an ongoing interest to identify alternative pesticidal agents to avoid the chronic problems associated with synthetic pesticides. Essential oils have shown promise as botanical pest control agents. In the present study, the essential oils of four members of the Lamiaceae (Callicarpa candicans, C. erioclona, C. macrophylla, and Karomia fragrans; Vietnamese names: Nàng nàng, Tu châu lông mem, Tu châu lá to and Cà diện, respectively), obtained from wild populations in Vietnam, have been obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry. The essential oils were formulated into microemulsions and the essential oils and their microemulsions were screened for mosquito larvicidal activity against Aedes aegypti, Aedes albopictus, Culex quinquefasciatus, and for molluscicidal activity against Pomacea canaliculata. Atractylone and (E)-caryophyllene dominated the volatiles of C. candicans (CCEO) and C. erioclona (CEEO), while the major component in C. macrophylla (CMEO) and K. fragrans (KFEO) was (E)-caryophyllene. The essential oils and microemulsions of both C. candicans and C. erioclona exhibited excellent larvicidal activity against all three mosquito species (Ae. aegypti, Ae. albopictus, and Cx. quinquefasciatus) with LC 50 values < 10 μg/mL. Additionally, the larvicidal activity of the microemulsions were significantly improved compared with their free essential oils, especially for C. candicans and C. erioclona. All four essential oils and their microemulsions showed excellent molluscicidal activity with LC 50 < 10 μg/mL. In most cases, the essential oils and microemulsions showed greater pesticidal activity against target organisms than the non-target freshwater fish, Oreochromis niloticus. The in silico studies on physicochemical and ADMET properties of the major components in the studied essential oils were also investigated and most of the compounds possessed a favorable ADMET profile. Computational modeling studies of the studied compounds demonstrated a favorable binding interaction with the mosquito odorantbinding protein target and support atractylone, β-selinene, and caryophyllene oxide as potential inhibitors. Based on the observed pesticidal activities of the essential oils and their microemulsions, the Callicarpa species Supporting information for this article is available on the WWW under
