“…Both the size and the polydispersion index obtained in our study are comparable with those recorded for other citrus EO-NPs (i.e. Bergamot EO-NPs) 34 . The change of the zeta potential from about zero in the case of unloaded NPs to about −30 mV for the different EO-NP formulations can be considered an indicator of the extent of EO loading in the nanoparticles, as confirmed by spectroscopic analyses that indicate an efficient loading (>90% w/w) for the different EO-NP systems.…”

“…In fact, nanoformulations can solve problems related to EO volatility, poor water solubility, and the tendency to oxidize 34 . In addition, nanoparticles are able to release the active compounds at the site of action gradually 37 , and also minimize the toxic effects on non-target organisms 38,39 .…”

“…Nanoparticles are known to be much more mobile than the bulk substances 48 . This characteristic enhances the penetration of the active ingredients into the insect tissue by direct contact through the insect’s cuticle or by ingestion 32,34,48 .…”

“…The encapsulation of EOs inside nanoparticles could reduce these problems, improving at the same time the efficacy and the induction of systemic activity due to the small size of the particles 32,33 . Specifically, polyethylene glycol (PEG) functionalised nanoparticles (NPs) considerably improve solubility in water and control pesticide release 34,35 .…”

The repeated use of conventional synthetic pesticides in crop protection leads to resistance development by pests along with a negative impact on the environment, particularly non-target arthropods. Plant-derived active compounds, such as essential oils (EOs), play a key role in sustainably controlling pests. The lethal and sublethal activity of citrus peel EOs as emulsions and included in polyethylene glycol (PEG) nanoparticles (EO-NPs) was determined against the invasive tomato pest Tuta absoluta. Their effects on the plants were also assessed. The results showed an overall good insecticidal activity of the compounds tested, with a higher mortality through contact on eggs and larvae by EO emulsions and through ingestion on larvae by EO-NPs. The nanoformulation also significantly reduced the visible toxic effects on the plants. The data collected suggest that these natural compounds, especially when nanoformulated, could be successfully used in integrated pest management programs for T. absoluta.
