Online Conference
The second international Conference in Material Science and Engineering. Organized by Laser Physics and Nanotechnology Unit, Benha University, Egypt. On 5-6 December 2020
Keywords: plant-based nanoparticles, acaricides, tick control, controlled release; environmental response.
Ticks (Acari: Ixodidae) are obligate blood-sucking ectoparasites that induce irritation and damage to the skin and transmit numerous pathogens to humans and animals as tick-borne encephalitis, Powassan, Borreliosis, Lyme, Tularemia, Ehrlichiosis, Anaplasmosis, Babesiosis, and Theilerioses. Tick control is achieved mainly through the application of chemical acaricides and repellents inducing environmental contamination, food residues, development of resistant strains. Consequently, eco-friendly pesticides would play a vital role in controlling tick-borne diseases. Many plants, mostly from the Lamiaceae family, showed acaricidal and repellent effects. Botanical acaricides could be used in organic farming and against resistant tick strains, but there are many constraints toward their commercialization as their degradation, stabilization, and standardization. Hopefully, Green metal nanoparticles, like silver, titanium dioxide, zinc oxide, nickel, and copper, mediated by plant-based compounds, are cheaper and single-step process and does not require toxic chemical compounds. Nanoformulations also protect the active compounds from environmental degradation and enable rapid penetration into ticks. Moreover, establishing intelligent and controlled pesticide release technologies using nanomaterials could increase pesticide-loading, improve the dispersibility and stability of active ingredients, and promote target ability. From the “one-health" perspective, such intelligent formulations could represent novel eco-friendly solutions after revealing their ecotoxicological profiles for the safety of the human, animal, and non-target organisms.
