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.

“…Concerning the pesticidal potential of EOs against S. oryzae , many plant species have been tested previously mainly as contact insecticides on filter paper or as fumigants [ 15 , 16 , 17 , 18 , 19 , 20 , 21 ]. For example, Mentha spicata L., Mentha rotundifolia (L.) Huds., and Mentha longifolia (L.) Huds.…”

Essential oil (EO)-based nanoemulsions (NEs) are promising grain protectants in the management of stored-product pests. However, the potential impact of the stored-grain species on the green insecticide effectiveness has been poorly studied. In this study, two concentrations of EO-based NEs from Carlina acaulis L., Mentha longifolia (L.) Huds., and Hazomalania voyronii (Jum.) Capuron were evaluated as insecticides against the major stored-product pest Sitophilus oryzae (L.) on barley, oats, and maize kernels. The C. acaulis EO-based NE applied at 1000 ppm on barley achieved the highest mortality, killing 94.4% of S. oryzae adults after a 7-day exposure, followed by 1000 ppm of H. voyronii EO-based NE (83.3%). The lowest mortality (1.1%) was recorded with 500 ppm of M. longifolia EO-based NE on maize after the same interval. All tested NEs exhibited elevated efficacy when applied on barley, while mortalities were lower on oats and maize. Furthermore, C. acaulis EO-based NE was the most effective when applied on all commodities, followed by H. voyronii and M. longifolia EO-based NEs. Overall, our results highlighted the significant impact of the stored cereal on the insecticidal effectiveness of EO-based NE used for stored-product pest control. Sitophilus oryzae adults on barley can be adequately controlled through the application of C. acaulis and H. voyronii EO-based NEs.

“…In particular, this is useful when volatile compounds are to be administered or when the active compounds can be toxic toward other species. Among possible carriers, polymer-based nanosystems are considered very promising due to their versatility and safety, this latter being especially warranted if natural macromolecules (Niculescu et al, 2021;Yeguerman et al 2022) are used to fabricate the nanocarriers. Therefore, choosing compatible matrices (Colzi et al, 2015) for the preparation of nanosystems, or, possibly, re-using by-products from the plant itself, is a procedure that can help the targeting of bioactive molecules while pursuing the aims of sustainability and circular economy (Clemente at al., 2018;Clemente et al 2019;Savy et al 2022).…”

Sustainability and circular economy are increasingly pushing for the search of natural materials to foster antiparasitic treatments, especially in the case of economically relevant agricultural cultivations, such as grapevine. In this work, we propose to deliver neem oil, a natural biopesticide loaded into novel nanovectors (nanocapsules) which were fabricated with a scalable procedure starting from Kraft lignin and grapeseed tannins. The ensuing formulations were characterized in terms of size and Zeta potential, showing that almost all the nanocapsules had size in the suitable range for delivery purposes (mean diameter 150-300 nm), with low polydispersity and su cient stability to ensure long shelf life. The target microorganisms were three reference fungal pathogens of grapevine (Botrytis cinerea, Phaeoacremonium minimum, Phaeomoniella chlamydospora), responsible for recurrent diseases on this crop: grey mold or berry rot by B. cinerea and diseases of grapevine wood within the Esca complex of diseases. Results showed that grapeseed tannins did not promote inhibitory effects, nor alone nor in combination with Kraft lignin. On the contrary, the e cacy of neem oil against P. minimum was boosted by more than 1-2 orders of magnitude and the parasite growth inhibition was higher with respect to a widely used commercial pesticide, while no additional activity was detected against P. chlamydospora and B. cinerea. HighlightsNeem Oil was loaded into novel nanocapsules formed by tannins and lignin; Nanocapsules had mean diameter of 150-300 nm with low polydispersity.Nanocapsules had a negative surface charge which guarantees good stability;Lignin-based nanocapsules enhance the e cacy of neem oil by more than 1-2 order of magnitude on Phaeoacremonium minimum.
